Big Global Warming Debate at The Villages (FL) Science Tech Club


The title of the debate was "Two Views on Human-Caused Global Warming". Fellow Villager Don Fogg took the AFFIRMATIVE and I (Ira Glickstein) took the NEGATIVE in a friendly but spirited debate with considerable participation by the overflow audience. Our mutual friend, Steve Hendrickson, was kind enough to video the entire event. The photos  in this Blog posting are frame grabs from his excellent video.

Our combined PowerPoint chart set is available from The Villages Science Technology Club at: https://drive.google.com/file/d/1YPiXPuaHLcXeP3p2D_d5AfNekEXMIwVg/view  

We agreed on five QUITE SPECIFIC debate ISSUES, as listed at the bottom of the following photo:


For the most part, this was a science-based debate because Don and I agree on most of the basic science. Our level of agreement was stated in the following stipulations:

Both parties agree, for purposes of this debate, that:
1.The Atmospheric “Greenhouse” Effect is true science. Atmospheric gases, mostly Water Vapor and CO2, are responsible for the Earth surface being about 33⁰C warmer due to this effect. All else being equal, a rise in CO2 will cause mean temperatures to rise. 
2.CO2 levels in the Atmosphere have been rising at an unprecedented rate over the past century, from less than 300ppmv to over 400ppmv. At least half of that rise is due to human activities, primarily burning of fossil fuels.
3.The Intergovernmental Panel on Climate Change (IPCC) has issued five “Assessment Reports” from 1990 to 2013, with projections for future warming based on over 100 Climate Models.
4.NASA-Goddard Institute for Space Studies (GISS) is the main US-government funded Climate agency, tracking, reporting, and adjusting historical US and world-wide terrestrial thermometer data (1880-present), and contributing to the IPCC.

5.The US government also funds satellite systems that measure lower atmospheric temperatures, available since 1979. University of Alabama at Huntsville (UAH) and Remote Sensing Systems (RSS) are the major US-government funded groups for satellite-based world-wide temperature tracking.

IRA'S MAIN DEBATE POINTS

1) While the Earth Surface has definitely warmed since 1880, and some portion of  that warming is due to human activities (mainly burning unprecedented quantities of fossil fuels and land use changes) the AMOUNT of warming has been inflated by around 0.5⁰C and the DEGREE of human-causation has been exaggerated.

2) The Official Climate Models, based on the IPCC and NASA-GISS Climate Theory, run HOT. They thus give an over-stated sense of danger and therefore urgency, which is not supported by the rather modest warming.

3) As Richard Feynman famously said
"It doesn’t matter how beautiful your theory is, it doesn’t matter how smart you are. If it doesn’t agree with experiment, it’s wrong."

The Official Climate Theory is wrong in that Climate Models based on that Theory run HOT compared to the observational data. Thus, the climate "experiment" results do not agree with the  theory. The Official Climate Team should correct their theory. Instead, they  have inflated their observational data!

I believe the major problem with the Climate Models is how they treat CLOUDS. Daytime clouds have a net NEGATIVE impact on warming, while nighttime clouds have a POSITIVE impact. The Climate Models assume, incorrectly IMHO, that the overall net effect of increasing clouds (daytime and nighttime) is POSITIVE, while, based on actual data, it is NEGATIVE. In addition, the Climate Models do not properly account for thunderstorms, which remove heat from the surface and move it into the Atmosphere where it can more easily be radiated out to space.

There are over 100 Official IPCC Climate Models that date from the early 1990's. These Climate Models have been updated with each Assessment Report issued. Taking their 2007 report, called "AR4", the average of all their Climate Model PREDICTIONS (which they call "projections") have tended to be WARMER, by a factor of two or three than the best worldwide temperature measurements.

[Added 13 Feb 2018] For example, when the AR4 Predictions are aligned with the Berkeley Earth Surface Air Temperature (as in the photo below), the predictions for the years following 2007 go up sharply by about 0.2⁰C, but actual measurements show an increase of less than 0.1⁰C.



As Yogi Berra famously said: "It's tough to make predictions, especially about the FUTURE."

Climate Model predictions about the PAST are called "retro-dictions" and one would expect any good Climate Model would retro-dict the PAST quite well, because the scientists constructing the models have actual data from the PAST in hand. Never-the-less, as  the photo shows, the average retro-dictions run hot by about 0.2⁰C for the period 1880 through 1940. [End of added material]


ADJUSTMENTS TO US TEMPERATURE DATA

As the following slide indicates, US terrestrial temperature data, based on thousands of observations of surface-based thermometers by dedicated Americans since 1880, has been adjusted by American scientists at NASA-GISS at least seven times between 1999 and the present.

The slide focuses on two specific very warm years, 1998 and 1934. However, the adjustments affected virtually all temperature data from the 1920's through the 1990's. US Temperatures for the years prior to the 1970's were cooled, and for the years following the 1970's were warmed.

As NASA-GISS reported in 1999, the US, in 1934, was over half a degree C (0.541⁰C) WARMER than 1998. This was, shall we say "inconvenient" since their objective was to alert the American public to what they thought was a future of catastrophic human-caused warming.

The data points on the chart are based on a surprisingly candid 14 Aug 2007 email from NASA-GISS Research Scientist Makiko Sato, PhD, to her boss James Hansen, PhD. (The email was released in 2010 due to a Freedom of Information Act (FOIA) action by Judicial Watch.) 

Sato's FOIA email details the results of seven adjustments (YOUR TAX DOLLARS AT WORK :^(.

Sato started in 2000 and 2001, where by two mighty analysis efforts she got 1934 to COOL by about a quarter degree C, and 1998 to WARM by a similar amount. However, even after  this effort, 1934 was still a bit WARMER than 1998.

The data sat undisturbed in her desk for four years, until 2005, when a third analysis kept 1934 about as COOL as it had been according to her year 2001 effort. However (HORRORS!!!) 1998 COOLED back down about a quarter degree C, back to the original values reported in 1999. So according to her 2005 analysis, the US in 1934 had been about a quarter degree C WARMER than 1998.

Sato's boss, James Hansen, was a key technical advisor to Al Gore for his "Inconvenient Truth" lecture tour and movie, scheduled for release in 2007. So, if  the Earth was supposed to be in a HUMAN-CAUSED CATASTROPHIC WARMING trend, it was "inconvenient" for the warmest US year in the last half of the 20th century to be COOLER than the warmest year in the first half. 

So, Sato did three more analyses in January 2007 (the fourth since 1998), March (2007 the fifth since 1998), and August 2007 (the sixth since 1998). She got 1934 and 1998 very close to the same temperatures. Indeed, although the January and August analyses had 1998 a bit COOLER, the March analysis, after heroic effort by Sato, got 1998 a teeny-tiny bit WARMER than 1934.

However, despite this triple re-analysis attack Sato's FOIA email ends with 1934 still a bit WARMER than 1934, but only by a teeny-tiny 0.003⁰C.

Never-the-less, in the years following Sato's 2007 email, NASA-GISS continued to plough your taxpayer dollars into re-analysis of the 1934 and 1998 data. I looked up the latest US data on their website, and 1998 is finally over a tenth degree C (0.114⁰C) WARMER than poor old 1934.

ON THE NASA-GISS WEBSITE THEY ADMIT "These adjustments caused an increase of about 0.5⁰C in the US mean for the period 1900 to 1990." See:   https://data.giss.nasa.gov/gistemp/faq/#q215
(NOTE: By my accounting, the actual increase is over 0.6⁰C, but "close enough for government work"!)

NASA-GISS also notes the adjusted data is only "1.6% of the Earth's surface". The implication being these adjustments have minimal impact on world-wide data.  See: https://data.giss.nasa.gov/gistemp/graphs_v3/

HOWEVER, IF AMERICAN SCIENTISTS CANNOT ANALYZE AMERICAN DATA TO WITHIN HALF A DEGREE C, WHY WOULD ANYONE BELIEVE WORLD-WIDE DATA (SOME OF IT FROM THIRD-WORLD COUNTRIES) AND ASSOCIATED ANALYSIS IS ANY BETTER?

I spot a definite WARMING TREND, do you? If we look at this data in future years, I fully expect 1998 to take its "rightful" place at least 0.5⁰C WARMER than bad old 1934. OUR TAX DOLLARS AT WORK.


The Official rationale for the repeated adjustments (at least seven by my count) is that, over the many years since 1880, US thermometer readers tended to read their thermometers at different times of day.We all know that early morning and late evening tends to be cooler than midday (sometimes by 10⁰C !) Also, when the thermometer sites are relocated, say from the local newspaper office to a new airport, the new site may be a bit warmer or cooler. So, those changes, quite obviously, have to be taken into account to make sure errors are not introduced.

Are we to believe that James Hansen (head of NASA-GISS starting in 1981) and his respected research scientists did not know about these Time of Observation and Site Relocation effects until 2000? Hansen had worked on Climate Science for over 19 years before he and his staff realized adjustments were necessary?

Does anyone believe that, when they finally figured out they had to make these adjustments, it  took them seven analyses, over a decade or more, to get the "RIGHT" answer?

I tend to believe that many government-funded research projects are done less than competently. However, I simply do not believe Hansen and Sato were that incompetent.

No, I think they saw it as their "duty" to warn us about an impending climate catastrophe (and thus keep taxpayer money coming in), so they beat the old US data mercilessly, until they got the "RIGHT" results. (The 1934 data was old enough to qualify for Social Security :^).

If these were the inflation-adjusted profit reports of a corporation trying to spin a tale of continually-increasing profits, and the data published in 1999 showed 1998 was $ 0.5 Billion LESS profitable than 1934, and seven subsequent published reports showed variously changing reports ending with a virtual tie, would anyone believe it? Any competent observer would suspect "the books have been cooked!"

A Global Warming Skeptic Guide for the Perplexed

How should responsible Global Warming Skeptics respond to opinions from intelligent members of the general public who have been perplexed by the Warmists and Alarmists?

NOTE: AN UPDATED VERSION OF THIS HAS BEEN PUBLISHED AT THE WORLD'S MOST POPULAR CLIMATE WEBSITE, SEE

http://wattsupwiththat.com/2014/09/10/a-guide-for-those-perplexed-about-global-warming/ 

PLEASE CLICK THE LINK TO SEE IT. PLEASE FEEL FREE TO JOIN THE CONVERSATION.

IN THE FIRST 12 HOURS, IT WAS VIEWED BY OVER 3,500 PEOPLE, 168 OF WHO TOOK THE TIME TO POST COMMENTS. AT 24 HOURS IT WAS UP TO OVER 10,000 PAGE VIEWS AND 237 COMMENTS. I EXPECT IT TO CONTINUE TO BE POPULAR, GAIN THOUSANDS MORE PAGE VIEWS AND BE RE-POSTED BY OTHERS. 

We should reply in a strictly fact-based way, using official sources, and being careful not to speculate or over-complicate the matter. Here is my shot at it.

At a recent meeting of a local discussion group a well-spoken retired teacher presented a list of important issues that, in his opinion, have received less coverage by the media than they deserve. "Climate Change" was on his list.

He said it was unfortunate that the main proponent of human-caused "Global Warning" was a prominent Democrat (former VP Al Gore), because that led to the issue becoming politicized, with his fellow Democrats on one side and Republicans on the other. He speculated that had a leading Republican promoted the same issue, the reaction would probably be the reverse.

He then raised several points, citing the NASA Goddard Institute for Space Studies (GISS), the UN Intergovernmental Panel on Climate Change (IPCC), and other expert sources. He said that Global Warming is really happening, with a rise of over 0.7⁰C, and we humans are the main cause due to our massive use of fossil fuels that generate atmospheric CO2, a greenhouse gas that warms the Earth.

During the discussion period I agreed that global warming is real, that atmospheric CO2 undoubtedly causes warming, and that some of the increased CO2 is certainly due to human actions. However, I pointed out that, although atmospheric CO2 levels continue to rise, and at an accelerating rate, global temperatures have not statistically increased for at least 15 years. Therefore, while CO2 levels have definitely caused some of the warming, and rising CO2 is mostly caused by human activities, CO2 cannot be the main cause.

The presenter assured me that he respected my opinions, but, while he was not a scientist, he was relying on scientists and scientific organizations that had studied the issue. He then read a few quotes, including one that said human actions were likely to lead to a "tipping point" where the ice caps melt and there is runaway warming on a catastrophic scale.

I have prepared the following strictly fact-based response, using sources the presenter himself mentioned and being careful not to speculate or over-complicate the matter.

1- It is undoubtedly true that average surface temperatures have increased significantly since 1880. Human activities are responsible for some portion of that warming. [The image below is the latest GISS Global Temperature Index anomaly. The black squares indicate the mean temperature anomaly for each 12-month calendar year. The thick red line indicates the mean temperature anomaly smoothed over 60 months (five years). This graphic shows a net increase of about 0.8⁰C (about 1.5⁰F) since 1880. While I think "data adjustments" have increased the apparent warming by a few tenths of a degree, I accept that warming since 1880 is at least 0.5⁰C (about 1⁰F)]

2- Atmospheric CO2 levels have risen steadily, and the rate of increase has doubled since reliable CO2 data from Mauna Loa became available around 1959. [The image below is the latest NOAA ESRL Atmospheric CO2 showing an increase of about 1 ppm/year in the 1960's and about 2 ppm/year in the 2000's. The current level is approaching 400 ppm. The pre-industrial level is estimated to have been about 280 ppm.]

3- When compared to actual polar satellite temperature observations, the IPCC climate models have predicted too much warming, particularly after 1998. [The image below is the latest RSS Global temperature anomaly since about 1979 when good global temperature data from polar orbiting satellites became available. Note how, from 1999 to the present, the actual observations of temperature (thick black line) consistently fall below the yellow band (IPCC climate model prediction range with supposed 95% probability).]

[NOAA Caption "Fig. 1.  Global (80S to 80N) Mean TLT Anomaly plotted as a function of time.  The thick black line is the observed time series from RSS V3.3 MSU/AMSU Temperatures.  The yellow band is the 5% to 95% range of output from CMIP-5 climate simulations.  The mean value of each time series average from 1979-1984 is set to zero so the changes over time can be more easily seen. Again, after 1998, the observations are likely to be below the simulated values, indicating that the simulation as a whole are predicting too much warming."] (my bold)
Please note that, according to the actual RSS polar satellite temperature observations (thick black line), there has been absolutely no net warming after 1998. Indeed, 2013 is about 0.6⁰C (more than 1⁰F) cooler than the middle of the predicted range, and even 0.3⁰C (more than 0.5⁰F) cooler than the lower edge of the predicted range. Also note that the thick black line falls well below the yellow band, which indicates that the statistical 95% confidence level claimed for the IPCC climate models is not valid. Over the most recent 15-year period, actual satellite temperature observations have consistently been cooler than the central prediction of the IPCC climate models, by from 0.2⁰C to 0.8⁰C (about 0.4⁰F to 1.5⁰F).   

4- According to the NASA GISS Global Temperature Index, when smoothed over a calendar year, there has been no net warming for 15 years. Even when smoothed over a longer period of five years, there has been no net warming for seven years. [The image below is a close-up of the upper right corner of the first image in this posting.]

[The black squares represent the temperature anomaly for each given calendar year (12 month average). Note that 1998 is warmer than 2013, indicating no net warming for 15 years. The thick red line represents the 5-year running mean (smoothed over 5 years which is 60 months). Note that 2003 is at the same temperature as 2010, indicating no net warming for at least seven years.]


CONCLUSIONS

All of the above facts and data is directly from official, government-sponsored climate research organizations, and I have provide web links so anyone can check them his- or herself. If any reader thinks I have distorted or misrepresented any of the above material I will appreciate it if he or she posts a comment to this blog detailing any objections. (If you cannot figure out how to post a blog comment, please send your material to me in an email to ira@techie.com and I will be happy to post it for you.)

Unlike the above, the following conclusions involve some speculation on my part.

a- Politicization of the issue. I agree that "Climate Change" and "Global Warming" have been way over-politicized. Had the main proponent been a Republican, positions might have been reversed. However, I cannot imagine any Republican President or VP or other Republican office-older of similar national prominence falling for the idea that we humans are responsible for the majority of the warming we have experienced, or that the warming process is likely to lead to global catastrophe. And, even if he or she went along with the initial dire predictions, any reasonable and responsible politician (of either party) would understand that the absolute disconnect between actual temperature observations and predictions of IPCC climate models invalidates the idea of human-caused catastrophic climate change, and reverse their positions.

b- Activists in the catastrophic climate change industry purposely misrepresent the views of responsible Skeptics by making a number of false claims:

  • FALSE CLAIM - Skeptics do not believe the basic science of the Atmospheric "greenhouse" effect. RESPONSE - We do accept that water vapor, CO2, and other 'greenhouse" gases are responsible for the Earth being around 33⁰C (60⁰F) warmer than it would be if there were no "greenhouse"gases in the Atmosphere. However, based on the failure of the IPCC climate models to comport with actual temperature observations for at least 15 years, we question the IPCC position that doubling of CO2 will warm the Earth surface by 1.5⁰C to 4.5⁰C (3⁰F to 8⁰F). For example, I believe the true value (called "climate sensitivity") is only a half or a third of what the IPCC claims.
  • FALSE CLAIM - Skeptics do not believe the Earth surface has warmed significantly since 1880. RESPONSE -  We do accept that average global surface temperatures have increased by at least 0.5⁰C (1⁰F) since pre-industrial times. Many of us think that the thermometer record is somewhat unreliable. It is a matter of official record that, in recent decades, old temperature data prior to the 1970's have been adjusted down by as much as 0.3⁰C (0.5⁰F) and date after the 1980's adjusted up, which has increased claimed net warming by a few tenths of a degree. NASA GISS and other official record-keepers say these "data adjustments" are valid, but many of us think they are self-serving. However, we could be wrong, and the net warming since 1880 might be as much as 0.8⁰C (1.5⁰F). 
  • FALSE CLAIM - Skeptics do not believe that human activities have any part in causing the warming. RESPONSE - We do accept that unprecedented burning of coal, oil, and natural gas, and some changes in land use, are responsible for a significant fraction of the actual warming. However, based on comparison of actual temperature observations with IPCC climate models, I am convinced that the majority of warming is due to natural causes and processes not under human control or influence.

Looking forward to your comments.

Global Warming in Perspective

GLOBAL WARMING IS REAL, BUT NOT A BIG DEAL


1) Some of the net Global Warming since 1880 is undoubtedly due to human actions. The Atmospheric "Greenhouse" Effect is real and water vapor (H2O) and carbon dioxide (CO2) are "greenhouse" gases.
2) The actual temperature rise and human responsibility for it have been exaggerated.  By their repeated and substantial "adjustments" to the US temperature record, the Official US Climate Team (NASA GISS) has admitted that it is unreliable.
3) Official Climate Theory is flawed because it is "handcuffed" to CO2 levels. None of the official Climate Models predicted the current 17-year "pause" in warming. CO2 levels continue to rise rapidly, but the predicted warming has not occurred. 

 I posted some of this material on 7 April at Watts Up With That, the world's most viewed climate website. In the first two days, it received almost five thousand page views and almost a hundred comments. Some commenters found my first chart confusing. The image above is a simplified version. I also presented some of this material to the "Civil Discourse Club" at the Colony Recreation Center in The Villages, FL on 7 April, and again at the Savannah Recreation Center on 14 April, with over 100 people at each venue. My PowerPoint Show is available for download: here

Going from left to right on the above graphic:

Atmospheric “Greenhouse” Effect, responsible for about 59°F (33°C) warming. This is the Natural Process that makes life on Earth as we know it possible. The mean temperature on the surface of the Earth is about 59°F (33°C) warmer due to Atmospheric absorption of long-wave radiation by "greenhouse" gases, and the subsequent "back-radiation" of some of this heat energy towards the Earth surface. (See my WUWT Visualizing series [Physical Analogy, Atmospheric Windows, Emission Spectra, and Molecules/Photons Light and Heat])

Ice Age Warming and Cooling, are Natural Cycles that have occurred about every 100,000 years according to the ice core records from the past 400,000 years. Since these cycles occurred well before humans appeared on Earth, they must be entirely natural. The climate is always changing, with up and down temperature jigs and jags at all time scales. The major Ice Age Cycles change temperatures over a range of about 13°F (7°C ).

Mean Global Warming Since 1880, According to the Official NASA GISS and IPCC Accounting, is 1.4°F (0.8°C). According to the IPCC, the majority of this Global Warming is due to human activities (mainly unprecedented burning of fossil fuels and land use that has reduced the albedo of the Earth). I have interpreted "majority" to mean about 70% and have therefore allocated 1°F (0.6°C) to Human-Causation and the remaining 0.4°F (0.2°C) to Natural Cycles.

Please notice that the Human-Caused warming is a minor uptick in temperature compared to the variations due to the Natural Cycles of Ice Age warming and cooling and the major Natural Process warming due to the Atmospheric "Greenhouse" Effect!

Even that small amount of warming is most likely exaggerated and NASA GISS and the IPCC have the proportion of human-caused and natural backwards. Actual warming is most likely about 1.0°F (0.6°C), with about 0.8°F (0.5°C) due to Natural Cycles, and the remaining 0.2°F (0.1°C) due to Human-Causation. 


Move from New York to Florida, My wife and I experienced considerable warming when we retired from full-time employment and moved from Upstate New York to Central Florida. The average temperature in Florida is about 20°F (11°C ) warmer than that in New York. While not exactly "Global" Warming, this warming was certainly due to our Human-Caused decision to move south, and, of course, we enjoy the resulting moderately higher temperatures :^). Our voluntary move caused many times more degrees of warming than the global warming since 1880!
Yearly and Daily Warming and Cooling:  Natural Cycles of the YEARLY 43°F (24°C ) temperature range in Central Florida (July mean minus January mean), and Natural Cycles of the DAILY 19°F (11°C ) temperature range we experience here. Please notice that these ranges are much larger than the Natural Cycles of the Ice Ages, and they recur on a daily or yearly basis in the temperate zones of the Earth. Again, these daily and yearly temperature cycles cause many times more degrees of warming and cooling than all the global warming since 1880!


THE OFFICIAL TEMPERATURE RECORD IS UNRELIABLE


The blink chart below illustrates how US thermometer data from the early 1900's to 1998 has been "adjusted" by NASA GISS to COOL DOWN data prior to the 1970's and WARM UP data after the 1970's. Please note that 1998, the warmest year of the 1990's, is now shown as warmer than 1934, the warmest year of the 1930's. When the same chart was originally published in 1999 by the same US-government-supported institute, the relationship was reversed. The net change in this relationship is 1.154°F (0.641°C). Both charts were downloaded in March 2014 from http://www.giss.nasa.gov/ 


We know that the US thermometer record is so unreliable that it has had to be "adjusted" several times by the official US Climate "Team" at GISS, see The Past is Not What it Used to Be, and Skeptic Strategy. and Climate Change Controversy.

Unless we believe that the world temperature record is more reliable than the US record, it is likely the world record has also been similarly "adjusted". Therefore, I have discounted the GISS estimate of Global Warming by about 30%, so actual warming is about 1.0°F (0.6°C). I believe the IPCC has over-estimated Climate Sensitivity by a factor of two or three, so I have allocated the majority of the warming 0.8°F (0.5°C) to Natural Cycles, and the remaining 0.2°F (0.1°C) to Human-Causation.

PLEASE NOTE: I do not claim that the "adjustments" are wrong, only that the underlying temperature data is unreliable. If that data was reliable, there would be no need for the repeated re-analysis and "adjustments" that have been done by the official Climate Team.

OFFICIAL CLIMATE MODELS HAVE FAILED

We have had good satellite records of Global Temperatures since 1979, so we no longer need to rely on the unreliable terrestrial temperature record. As shown in the chart below, the satellite record (blue arrows) shows moderate warming from 1979 to about 1996, and then a "pause" in warming that continues to this day. The wiggly lines on the chart show the theoretical Climate Models, with the heavy red line (and the red arrow) indicating the average of all the models. All of the official Climate Models have failed because the underlying Climate Theory is flawed.


Climate Sensitivity is the Mean Temperature Rise expected if CO2 levels double. So far, from 1979 to the present, CO2 has increased from about 330 ppmv to nearly 400 ppmv, a 40% rise. If that rate of CO2 rise continues, as it almost certainly will given the rapid industrialization of China, India, and other countries, the 1979 CO2 level will double by 2060.
 

The IPCC claims Climate Sensitivity is in the range of 2.7°F (1.5°C) to 8.1°F (4.5°C), and their Climate Models reflect that range. As the chart above indicates, when their Climate Models are run from 1979 to 2013, the expected temperature rise is about 1.6°F (0.9°C) . However, the actual temperature rise since 1979 is only about 0.3°F (0.17°C) , a fraction of what was predicted!

Based on the evidence of this chart, that the IPCC has over-estimated Climate Sensitivity by at least a factor of two to three.  I believe actual Climate Sensitivity is closer to the range of 1.0°F (0.6°C) to 2.0°F (1.1°C).



THE SCIENTIFIC METHOD vs THE OFFICIAL CLIMATE THEORY
As Richard Feynman famously said,

It doesn't matter how beautiful your theory is. It doesn't matter how smart you are. If it doesn't agree with experiment it is wrong!
The Official Climate Theory is based on a gross over-estimate of CO2 Climate Sensitivity. Reliable satellite-based temperature DATA since 1979 proves that the Official Climate Theory is WRONG by a factor of at least two or three.

According to the Scientific Method, if your theory doesn't agree with the observational DATA, you need to change your THEORY.

The Official Climate Team seems to have changed the DATA!

Climate Change (aka Global Warming)

This posting is based on a talk to the Technology, Engineering, Science Plus Club, The Villages, FL, 26 May 2011. This group is a well-educated audience familiar with science and technology, but not necessarily fully cognizant regarding the current controversy.

Powerpoint charts available for download here

Skeptic Strategy for Talking About Global Warming

This Powerpoint chart set may be used as the basis for a skeptic-oriented talk or debate about Climate Change (aka Global Warming). Talking points are provided in the Notes section of each chart to help understand the main points made.

My “credentials” for preparing this slide set include:

  • Guest Contributor to the most popular climate website in the world, http://wattsupwiththat.com/author/iraglickstein/

  • Associate Professor of System Engineering at University of Maryland

  • System Engineer (Advanced Avionics and Visionics, Route Planning, Decision Aiding, Five Patents ... at IBM, Lockheed-Martin)

  • PhD in System Science (Binghamton University, 1996); MS in System Science (Binghamton); Bachelors in Electrical Engineering (CCNY)


If you saw the highly-rated 2006 movie An “Inconvenient” Truth you probably remember the scene depicted in the photo above.

Former VP Al Gore shows the ice core record of carbon dioxide (CO2 – in red) and temperature (in blue) over the past 600,000 years and he points out the obvious correlation between the two curves. When one goes up, so does the other. When one goes down, so does the other.

He then mounts a platform and is lifted high on the stage, showing how high CO2 levels are getting. He is then raised even higher to indicate where CO2 levels will be 30 years hence at the rate we are going if nothing is done about them.

The implication is that, if CO2 reaches that level, temperatures, which are clearly well-correlated, will rise as well. OMG ! At those high temperatures, the Arctic and Antarctic ice caps will melt, exposing the bare Earth beneath, reducing the albedo of the Surface and causing still more short-wave Solar energy to be absorbed. That could lead to still more warming and a “tipping point” catastrophe of major proportions. As the ice melts, low-lying islands and coastal areas will be submerged, killing and displacing billions of people.

Clearly, something needs to be done on a worldwide basis to stop further burning of fossil fuels and land use activities that reduce the albedo.

The message was so powerful that it earned Al Gore and his movie an Oscar and a Nobel prize in 2007. It came to be known as Catastrophic Anthropomorphic Global Warming (CAGW).

But wait, there is more to the story! If we examine the ice core data carefully, we discover that the temperatures rise about 800 years or more before the CO2 goes up. Temperature also falls 800 or more years before CO2 goes down. This lag of temperature behind CO2 is true for the entire 600,000 year ice core record. OOPS, is this another “inconvenient” truth?

Yes, there is correlation and possibly causation. But, in which direction?

HMMM .. If A “causes “ B, then A has to happen before B. Right? If, as Gore implies, CO2 “causes” temperatures to rise, then one would expect CO2 to rise before temperatures. Right?

Thus, all the ice core data proves is that temperature “causes” CO2 –or– that something else causes both temperature and CO2.

Those who believe that higher CO2 will cause temperatures to rise, due to the Atmospheric “greenhouse effect” point to the unprecedented levels of burning of fossil fuels and the undoubted rise of CO2. But, if it is unprecedented, and due to human activities, what does the ice core record have to tell us about the current situation? Humans could have had absolutely no role in the Global Warming and Global Cooling cycles of the ice ages. So, why did Gore bring it up?

Climate Change (AKA Global Warming)

I've been blogging as a Guest Contributor over at Watts Up With That? the world's most viewed climate blog. Here are some graphics I created that may be of interest.

This one is from The PAST is Not What It Used to Be where I discuss the Data Bias that I think has exaggerated Global Warming since 1880 by about 0.3ºC.
The blink graphic switches between two different sets of US Annual Mean Temperature data covering the same years published by NASA GISS (Goddard Institute for Space Studies). My annotations remain fixed to show the changes.

Notice how the 1999 version has the years before 1960 warmer, by about 0.1ºC as compared to the same data published this year! Note also how the 2011 version has the data for 1980 and afterwards warmer, by up to 0.2ºC as compared to the same years on the 1999 version! Why would data that has been in hand for decades have to be adjusted in this "see-saw" way, if not to exaggerate the amount of warming in recent years? (That is Dr. James Hansen, head of NASA GISS, juggling the Earth and his impact on our economy.)


The second graphic is from Do We Care if 2010 is the Warmist Year In History?. It reproduces a NASA GISS email from Dr. Makiko Sato to Hansen, released in an FOIA request, in which she recounts the seven versions of US Annual Mean Temperature published for 1934 and 1998.
I've annotated that email with a graph showing how 1934 was warmer than 1998 by more than 0.5ºC when the first version was published in 1999. When the exact same raw data was reanalyzed and republished in 2001, 1934 temperatures (which were by then old enough to collect Social Security :^) were somehow reduced by almost 0.2ºC and 1998 data got boosted by nearly 0.1ºC, to reduce 1934's lead.

The graphic shows how 1934 continued to get cooler and 1998 got warmer (though 1998 had a surprising setback in the 2006 version :^) until, in the last analysis, they were in a virtual tie. Note that all this data is from an official NASA GISS email.

Sadly, after the date of the email, further reanalysis was done to make 1934 about an eighth of a degree cooler than 1998. Sad loss for the old guy. This clearly demonstrates the NASA GISS desire to make the more recent year warmer to prove Global Warming. It was embarassing to have the older data beat the more recent in the race to be warmer. Kind of like losing a footrace to your grandfather! So they did a Photoshop on the photo finish image to correct their earlier error.

Question: If the final version (1934 cooler than 1998) is correct, then the initial seven versions must all be in error?

Sunspots - Prediction of New "Dalton Minimum"

Global COOLING Anyone?

Nearly TWO YEARS ago (January 2009 and December 2009 [nearly FIVE years ago now]) I predicted that the now current Sunspot Cycle #24 would peak at 80. I am now revising that down to a peak of only 60, based on a great posting by David Archibald at Watts Up With That, the most widely read and respected climate website in the world.

We may be in for a new Dalton Minimum similar to the period from 1790 to 1830 when temperatures were unusually low. Indeed, we may come to welcome the cushion of warmth, perhaps 0.1 to 0.2ºC, that may be due to recent human activities. (The IPCC Climate "Team" claims 0.6 to 0.8ºC rise mostly due to human-caused Global Warming, but that is most likely an over-estimate.)

As the graphic shows, at the time I made the 80 prediction, NASA was predicting a peak of 104, having revised it downwards a couple of times from their original, wildly high estimate of a 156 peak. The most recent NASA projection is 90.

Description of the Graphic

[Click graphic for larger version] The base for the graphic is from Archibald's posting (Figure 9). The BROWN curve plots actual data from Solar Cycles #3, #4, #5, and #6 (late 1700's through early 1800's). The GREEN curve plots the corresponding actual data for Solar Cycles #22, #23, and the first part of #24, (1990 through December 2010)

I have added the annotations in RED and GRAY, indicating NASA's incredible string of highly incorrect predictions from 2006 to most recent (red hoops) and my original January 2009 prediction and my revised prediction (gray hoops).

Historical Correlation of the Dalton and Maunder Minima with Sunspot Activity

The very cold temperatures from 1790 through 1830 are usually explained as being due to increased volcanic activity, including the Mount Tambora eruption of 1815 that caused the Year Without a Summer, 1816. However, low solar activity, with peak Sunspot counts of only 45 for Sunspot Cycles #5 and #6, is most likely the major cause. Even lower Sunspot counts (below 10) occurred during the earlier Maunder Minimum (1650 to 1700). These periods of Global Cooling were marked by crop failures that are inimicable to human life.

Explanation of the Effect of Sunspot Counts on Climate

The NY Times interviewed Henrik Svensmark last year about his theory of Sunspots and Climate:

One possibility proposed a decade ago by Henrik Svensmark and other scientists at the Danish National Space Center in Copenhagen looks to high-energy interstellar particles known as cosmic rays. When cosmic rays slam into the atmosphere, they break apart air molecules into ions and electrons, which causes water and sulfuric acid in the air to stick together in tiny droplets. These droplets are seeds that can grow into clouds, and clouds reflect sunlight, potentially lowering temperatures.

The Sun, the Danish scientists say, influences how many cosmic rays impinge on the atmosphere and thus the number of clouds. When the Sun is frenetic, the solar wind of charged particles it spews out increases. That expands the cocoon of magnetic fields around the solar system, deflecting some of the cosmic rays.

But, according to the hypothesis, when the sunspots and solar winds die down, the magnetic cocoon contracts, more cosmic rays reach Earth, more clouds form, less sunlight reaches the ground, and temperatures cool.

“I think it’s an important effect,” Dr. Svensmark said, although he agrees that carbon dioxide is a greenhouse gas that has certainly contributed to recent warming.

Dr. Svensmark and his colleagues found a correlation between the rate of incoming cosmic rays and the coverage of low-level clouds between 1984 and 2002. They have also found that cosmic ray levels, reflected in concentrations of various isotopes, correlate well with climate extending back thousands of years.
Conclusion

Before we destroy industrial economies with extreme measures to reduce carbon emissions, it will be a good idea to consider how that might not only not be effective in reducing human-caused Global Warming, but how a bit of carbon-warming could be welcome during the coming period of Global Cooling. By the way, I am still in favor of an across-the-board Carbon Tax because the steady rise in CO2 levels is unprecedented and that is the most intelligent way to utilize our market-based economic system to speed the development of renewable energy sources. However, that effort has a multi-decade time horizon and is no emergency.

Should NASA be trying to scare us over the temperature rise?


[From Rick] A couple of weeks ago, our local news pumped a NASA GISS (Goddard Institute for Space Studies - Hansen's group) news release regarding 'Yet Another Temperature Record.'

My first thought was - HEY - why is this newsworthy? If the temperature has been gradually warming since the last ice age, then EVERY year is likely to set new temperature records. It reminded me of the newscaster that said on election night last year "70% of the votes have been counted and that number is expected to go higher!" I wondered how often they went lower!

But then I thought some about the appearance of the graph as NASA formatted it. What I decided to do was make a little video about that which is here:



[Click on arrow to play video] It will take 2 minutes of your remaining life to watch this and I can't guarantee it will be worth it, but it IS a different point of view.

In putting this together, I noted that the temperature records for Central England (available through Hadley Center but the website I used is either down at the moment (or taken offline as a result of Climategate). The Wikipedia entry is here.

So what I was wondering was - if CO2 didn't begin it's sharp rise until the mid 20th century, can that be picked out of the temperature record.
In NASA's chart - MAYBE - you will see that there is a recent trend that MIGHT fall outside the uncertainty in NASA's graph. However, if you also look at the Central England chart, it might not be so obvious. Especially since similar long term rises in the record have occasionally exceeded the slope of recent rises. Even back to pre-industrial times - well before any significant CO2 rise!

Perhaps you will disagree.


Another note - I have not done ANY 'corrections' to the NASA mean temperatures. There have been numerous suggestions of either inappropriate, inadequate or unnecessary corrections to the temperature record (esp. urban heat island and siting corrections). Depending on your take, these might well remove the remaining datapoints that fall outside the error bars in the plots. If this were done, I think that ANY CO2 footprint would be very hard to justify, EPA and IPCC notwithstanding!


What do I believe? Results of experiments where a hypothesis may be isolated and tested, preferably, but those are difficult to come by in climate science. I rarely believe models unless they are validated (even though creating and validating models was a significant part of my career) - it's just too easy to create 'results' without accurately documenting the assumptions and starting conditions required to simulate the models.


I imagine that CO2 does have an impact on the climate - and I doubt it will be measured anytime soon. Until then I think that political action (e.g. cap and trade) falls somewhere between
Unwise and Folly!

I'd appreciate hearing if you find the video to clarify your understanding or to trigger any new insights for you.

Seeking inputs on UHI corrections.

[From Rick] This post seeks inputs on the status of Urban Heat Island (UHI) correction in temperature reconstructions. The information I have is a bit dated and sounds as though it might be one-sided. [Figure above is from Steve McIntyre. It is found in both of the Climate Audit links below.]

In any case, here's what my limited data collection has in it:

I mentioned to Ira having seen something on the difference between NOAA's and NASA's (GISS) use which I found at Climate Audit: NOAA versus NASA-1/20/09. McIntyre also refers to a post a few days earlier with a bit more data: Climate Audit: NOAA versus NASA-1/16/09


The figure above suggests that the NOAA temperature dataset from about 1930-1940 to be 0.1°C colder than the GISS dataset - and by 2000, 0.2°C warmer than the GISS. If I'm interpreting this correctly, the NOAA chart would suggest more warming than GISS of about 0.3°C (0.5°F) over the last 70 years. This 0.3°C difference MIGHT be the effect of GISS attempting to correct for UHI more extensively than NOAA.

US Version of Climategate Coming?

Will NASA GISS (Goddard Institute for Space Studies) join the UK Climatic Research Unit (CRU) in the Climategate mess? Could be!

The UK CRU version of Climategate centered around whether the 1990's were warmer than any time in the past 1000 years. The US GISS version could be about whether 1998 was warmer than 1934!

It seems the temperature readings were adjusted six times after analysis in July 1999 indicated that the temperature anomaly for 1934 was nearly 60% higher than for 1998. See the above graphic for how GISS adjusted 1934 down and 1998 up until 1998 was warmer than 1934 (the January 2007 analysis) or at least virtually indistinguishable (the March and August 2007 analyses).

Sunspots Coming 'Round the Mountain When They Come?

The best experts at NASA have been predicting the imminent ramp-up of Sunspot cycle #24 since 2006. Well, here it is almost 2010, over three years later, and there has been a bit of an upsurge in Sunspot activity. At long last, it appears a Sunspot ramp-up may be coming 'round the mountain* pretty soon - but they won't be drivin' six white horses when they come!

The base figure above is from NASA/NOAA and shows their latest prediction (May 2009) which is the lowest and latest of the four red hoops. You can see that the actual Sunspot observations (black jig-jags with blue smoothing) do not quite match up with NASA's latest prediction. They also fall far short of the previous predictions which I have annotated into the figure as the three higher red hoops. [Click on image for larger version.]

The Sunspots are Coming! The Sunspots are Coming?

This colorful image is not an aboriginal prayer rug, but plenty of folks at NASA are "praying" it is evidence long-delayed Solar Cycle #24 has started or is about to start. As I reported last month in An "Inconvenient" Minimum and back in January in Where Have All the Sunspots Gone?, NASA previously predicted SC#24 would start late 2006 or early 2007. It is at least two years late.

No one can tell if the old cycle has ended until the new cycle has built up some steam over about a six month period. Well, the above Sunspot Prayer Rug may provide new evidence they may be able to declare SC#24 actually started last December or January.

DESCRIPTION OF FIGURE

The vertical axis is latitudes on the Sun, with the Sun's equator at the middle. The horizontal axis is years, from mid-1994 to the present. The red-yellow bands represent solar jet streams, thousands of miles below the surface of the Sun.

The vertical blue line at the left indicates when SC#22 ended and SC#23 started. Note that the start of a solar cycle is marked by a jet stream that initiates at about 45º North and South latitudes and spreads up and down as the years go by. SC#23 began in 1997 when the jet stream from SC#22 got down to what they call the "critical latitude" of 22º. NASA is excited that the jet stream from SC#23 is now down to about that critical latitude! That, they say, could (finally) mark the start of (long-awaited) SC#24.

DISCUSSION

Well, they could be correct - or not. The black contours on the Sunspot Prayer Rug represent sunspot activity. Note that the black contours representing SC#22 end in 1997. Nearly simultaneously, new black contours representing SC#23 sunspots begin in the mid-latitudes.

A possible problem with the NASA interpretation is that the SC#23 sunspots end in mid-2008, but the SC#24 sunspots have not cranked up yet, a year later. This is very different from the transition between SC#22 and SC#24 when the new cycle started in earnest immediately after the old cycle ended. Why is this transition so different from the previous one? Could the year-long sunspot pause indicate a more fundamental change in the Sun's internal, natural cycle behavior? Perhaps the idea that a new cycle will begin when the jet stream gets to 22º latitude does not apply in the current and very different situation?

HOW YOU CAN HELP NASA

A few weeks ago, I added a new feature to this Blog where you can watch the day-to-day development of the next sunspot cycle. Have a look in the right-hand column, just below the Dilbert comic for a NASA-supplied image of the Sun. That image will change daily and allow you to help NASA look for sunspots.

WHY DO YOU CARE ABOUT SUNSPOTS?

As described in a previous posting on this Blog, there is an historical connection between periods of low sunspot activity and cooling trends. If the start of SC#24 is further delayed, it is likely it will peak later and at a lower level than originally expected. If we are lucky enough to get a series of weak sunspot cycles, that may provide decades of cooling that may counteract the estimated 0.5ºC actual warming our Earth has experienced over the past 150 years.

Although CO2 levels continue to increase at a rapid pace, it appears the Global Warming trend has abated, or perhaps reversed a bit, over the past ten years. A bit of Global Cooling will give us breathing room to correct our excessive release of previously-sequestered carbon (coal, oil, gas) into the atmosphere. Right now, the politicos are hell-bent on imposing the Cap & Trade Scam that will further destroy our economy and not reduce Global Warming very much. Let's hope they will reject that approach and work on something more conservative that will actually work, such as the Revenue-Neutral Carbon Tax .
