Warming over-estimated by 30-50%

Warming during past century overestimated by 30-50%

We might anticipate temperatures to accelerate downwards shortly


5 Mar 09 - A recent paper by meteorologist Joseph D’Aleo, Executive Director of Icecap, shows that warming during the past century may have been overestimated by 30-50%.

The problem is that several global data bases (GISS, GHCN, CRU) include station dropout, missing data, siting issues, and insufficient or even no adjustment for urbanization. This makes them unusable or even unreliable for trend analysis.

Using USHCN data from the United States - which at least is stable and has much less missing data - D’Aleo shows that temperature trends are cyclical in nature and correlate far better with solar and multidecadal ocean cycles.

D’Aleo’s shows that short term fluctuations are driven by factors such as ENSO and volcanic eruptions, while longer term cycles are mainly driven by cycles in the sun and oceans (although changes in the last half century have been increasingly blamed on humans).

A more active sun is a brighter slightly hotter sun, and when the sun is hotter the earth is a little hotter. This small effect is magnified by other more indirect solar influences. When the sun is more active although its brightness (mainly visible light) only increases by 0.1%, the ultraviolet radiation increases by 6-8% and the even shorter wavelengths by a factor of two or more. These UV rays create and destroy ozone in the high atmosphere, both of which are exothermic effects and produce heat.

Work by Labitzke and Shindell at NASA GISS have shown this to be important. Shindell showed how this factor may have been responsible for the little ice age.

When the sun is more active there are more flares and eruptive activity which cause rapid increases in the solar winds, which in turn causes ionization storms in the earth’s atmosphere with resultant heating.

Also importantly, an active sun causes the earth’s magnetic shield to diffuse more cosmic rays from reaching into our atmosphere. Since these rays have a low water cloud formation enhancing effect (recently confirmed in the laboratory), an active sun usually means less low clouds and thus warmer temperatures. In all these cases, a more active sun brings warming.

Ocean Multidecadal Cycles

The Pacific and Atlantic undergo multidecadal cycles the order of 50 to 70 years. In the Pacific this cycle is called the Pacific Decadal Oscillation. A warm Pacific (positive PDO Index) from 1922 to 1947 and again 1977 to 1997 was accompanied by more El Ninos, while a cool Pacific was accompanied by more La Ninas (in both cases a frequency difference of close to a factor of 2).

Scafetta and West (2007) have suggested that the total solar effect may be responsible for at least 50% of the warming since 1900.

Since El Ninos have been shown to lead to global warming and La Ninas global cooling, this should have an affect on annual mean temperature trends in North America.

Clearly, US annual temperatures over the last century have correlated far better with cycles in the oceans and sun than carbon dioxide. The correlation with carbon dioxide seems to have vanished or even reversed in the last decade.

Given the recent cooling of the Pacific and Atlantic and rapid decline in solar activity, we might anticipate given these correlations, temperatures to accelerate downwards shortly.

Did you catch that? We might anticipate temperatures to accelerate
downwards shortly.

Greenhouse theory disproved a century ago

Greenhouse Theory Disproved a Century Ago

The claim that carbon dioxide (CO2) can increase air temperatures by "trapping" infrared radiation (IR) ignores the fact that in 1909 physicist R.W. Wood disproved the popular 19th Century thesis that greenhouses stayed warm by trapping IR. Unfortunately, many people who claim to be scientists are unaware of Wood's experiment which was originally published in the Philosophical magazine , 1909, vol 17, p319-320.

Wood was an expert on IR. His accomplishments included inventing both IR and UV (ultraviolet) photography. Wood constructed two identical small greenhouses. The description implies the type of structure a gardener would refer to as a "coldframe" rather than a building a person could walk into. He lined the interior with black cardboard which would absorb radiation and convert it to heat which would heat the air through conduction. The cardboard would also produce radiation. He covered one greenhouse with a sheet of transparent rock salt and the other with a sheet of glass. The glass would block IR and the rock salt would allow it to pass. During the first run of the experiment the rock salt greenhouse heated faster due to IR from the sun entering it but not the glass greenhouse. He then set up another pane of glass to filter the IR from the sun before the light reached the greenhouses. The result from this run was that the greenhouses both heated to about 50 C with less than a degree difference between the two. Wood didn't indicate which was warmer or whether there was any difference in the thermal conductivity between the glass sheet and the rock salt. A slight difference in the amount of heat transfered through the sheets by conduction could explain such a minor difference in temperature.

The two sheets probably didn't conduct heat at the same rate. The experiment conclusively demonstrates that greenhouses heat up and stay warm by confining heated air rather than by trapping IR. If trapping IR in an enclosed space doesn't cause higher air temperature than CO2 in the atmosphere cannot cause higher air temperatures.

The heated air in the greenhouses couldn't rise higher than the sheets that covered the tops of the greenhouses. Heated air outside is free to rise allowing colder air to fall to the ground. Atmospheric CO2 is even less likely to function as a barrier to IR or reflect it back to reheat the ground or water than the sheet of glass in Wood's greenhouse. The blackened cardboard in Wood's greenhouses was a very good radiator of IR as is typical of black substances. The water that covers 70% of earth's surface is a very poor radiator and produces only limited amounts of IR as is typical of transparent substances. Water releases heat through evaporation rather than radiation.

The glass sheet provided a solid barrier to IR. Atmospheric CO2 is widely dispersed comprising less than 400 parts per million in the atmosphere. Trapping IR with CO2 would be like trying to confine mice with a chain link fence. Glass reflects a wider spectrum of IR than interacts with CO2. The glass sheets reflected IR back toward the floor of the greenhouse. CO2 doesn't reflect IR.

At the time of Wood's experiment, it was believed that CO2 and other gas molecules became hotter after absorbing IR. Four years later Niels Bohr reported his discovery that the absorption of specific wavelengths of light didn't cause gas atoms/molecules to become hotter. Instead, the absorption of specific wavelengths of light caused the electrons in an atom/molecule to move to a higher energy state. After absorption of light of a specific wavelength an atom couldn't absorb additional radiation of that wavelength without first emitting light of that wavelength. (Philosophical Magazine Series 6, Volume 26 July 1913, p. 1-25)

Unlike the glass which reflects IR back where it comes from, CO2 molecules emit IR up and sideways as well as down. In the time interval between absorbing and reemitting radiation, CO2 molecules allow IR to pass them by. Glass continuously reflects IR. Those who claim that CO2 molecules in the atmosphere can cause heating by trapping IR have yet to provide any empirical scientific evidence to prove such a physical process exists. The experiment by R.W. Wood demonstrates that even a highly reflective covering cannot cause heating by trapping IR in a confined space. There is no way CO2, which at best only affects a small portion of the IR produced by earth's surface, can heat the atmosphere by trapping IR. Contrary to the lie repeated in news stories about climate, science doesn't say that CO2 is causing higher temperatures by trapping IR. Empirical science indicates that no such process exists in this physical universe.

More Than 650 Scientists Dissent Over Warming Claims
231-Page Report Now Available
By Marc Morano, 12/11/2008 7:52:15 AM

INTRODUCTION:

Over 650 dissenting scientists from around the globe challenged man-made global warming claims made by the United Nations Intergovernemntal Panel on Climate Change (IPCC) and former Vice President Al Gore.

This new 231-page U.S. Senate Minority Report report -- updated from 2007’s groundbreaking report of over 400 scientists who voiced skepticism about the so-called global warming “consensus” -- features the skeptical voices of over 650 prominent international scientists, including many current and former UN IPCC scientists, who have now turned against the UN IPCC.

See the full report here: http://epw.senate.gov/public/index.cfm?Fus...5b-2a1411df5804

This updated report includes an additional 250 (and growing) scientists and climate researchers since the initial release in December 2007. The over 650 dissenting scientists are more than 12 times the number of UN scientists (52) who authored the media-hyped IPCC 2007

Summary for Policymakers.

The chorus of skeptical scientific voices grow louder in 2008 as a steady stream of peer-reviewed studies, analyses, real world data and inconvenient developments challenged the UN and former Vice President Al Gore's claims that the "science is settled" and there is a "consensus." On a range of issues, 2008 proved to be challenging for the promoters of man-made climate fears. Promoters of anthropogenic warming fears endured the following: Global temperatures failing to warm; Peer-reviwed studies predicting a continued lack of warming; a failed attempt to revive the discredited “Hockey Stick”; inconvenient developments and studies regarding CO2; the Sun; Clouds; Antarctica; the Arctic; Greenland; Mount Kilimanjaro; Hurricanes; Extreme Storms; Floods; Ocean Acidification; Polar Bears; lack of atmosphieric dust; the failure of oceans to warm and rise as predicted.

In addition, the following developments further secured 2008 as the year the “consensus” collapsed. Russian scientists “rejected the very idea that carbon dioxide may be responsible for global warming”. An American Physical Society editor conceded that a “considerable presence” of scientific skeptics exist. An International team of scientists countered the UN IPCC, declaring: “Nature, Not Human Activity, Rules the Climate”. India Issued a report challenging global warming fears. International Scientists demanded the UN IPCC “be called to account and cease its deceptive practices,” and a canvass of more than 51,000 Canadian scientists revealed 68% disagree that global warming science is “settled.”

This new report issued by the Senate Environment and Public Works Committee's office of the GOP Ranking Member is the latest evidence of the growing groundswell of scientific opposition challenging significant aspects of the claims of the UN IPCC and Al Gore. Scientific meetings are now being dominated by a growing number of skeptical scientists.

The prestigious International Geological Congress, dubbed the geologists' equivalent of the Olympic Games, was held in Norway in August 2008 and prominently featured the voices of scientists skeptical of man-made global warming fears. [See Full report Here: & see: Skeptical scientists overwhelm conference: '2/3 of presenters and question-askers were hostile to, even dismissive of, the UN IPCC' ]

Even the mainstream media has begun to take notice of the expanding number of scientists serving as “consensus busters.” A November 25, 2008 article in Politico noted that a “growing accumulation” of science is challenging warming fears, and added that the “science behind global warming may still be too shaky to warrant cap-and-trade legislation.” Canada’s Financial Post noted on October 20, 2008, that “the number of climate change skeptics is growing rapidly.” New York Times environmental reporter Andrew Revkin noted on March 6, 2008, "As we all know, climate science is not a numbers game (there are heaps of signed statements by folks with advanced degrees on all sides of this issue)," Revkin wrote. In 2007, Washington Post Staff Writer Juliet Eilperin conceded the obvious, writing that climate skeptics "appear to be expanding rather than shrinking."

Skeptical scientists are gaining recogniction despite what many say is a bias against them in parts of the scientific community and are facing significant funding disadvantages. Dr. William M. Briggs, a climate statistician who serves on the American Meteorological Society's Probability and Statistics Committee, explained that his colleagues described “absolute horror stories of what happened to them when they tried getting papers published that explored non-‘consensus’ views.” Briggs, in a March 4, 2008, report, described the behavior as “really outrageous and unethical behavior on the parts of some editors. I was shocked.” [Note: An August 2007 report detailed how proponents of man-made global warming fears enjoy a monumental funding advantage over skeptical scientists. LINK and a July 2007 Senate report detailing how skeptical scientists have faced threats and intimidation.

Highlights of the Updated 2008 Senate Minority Report featuring over 650 international scientists dissenting from man-made climate fears:

“I am a skeptic…Global warming has become a new religion.” - Nobel Prize Winner for Physics, Ivar Giaever.

“Since I am no longer affiliated with any organization nor receiving any funding, I can speak quite frankly….As a scientist I remain skeptical. “The main basis of the claim that man’s release of greenhouse gases is the cause of the warming is based almost entirely upon climate models. We all know the frailty of models concerning the air-surface system” - Atmospheric Scientist Dr. Joanne Simpson, the first woman in the world to receive a PhD in meteorology, and formerly of NASA, who has authored more than 190 studies and has been called “among the most preeminent scientists of the last 100 years.”

Warming fears are the “worst scientific scandal in the history…When people come to know what the truth is, they will feel deceived by science and scientists.” - UN IPCC Japanese Scientist Dr. Kiminori Itoh, an award-winning PhD environmental physical chemist.

“The IPCC has actually become a closed circuit; it doesn’t listen to others. It doesn’t have open minds… I am really amazed that the Nobel Peace Prize has been given on scientifically incorrect conclusions by people who are not geologists,” - Indian geologist Dr. Arun D. Ahluwalia at Punjab University and a board member of the UN-supported International Year of the Planet.

“So far, real measurements give no ground for concern about a catastrophic future warming.” - Scientist Dr. Jarl R. Ahlbeck, a chemical engineer at Abo Akademi University in Finland, author of 200 scientific publications and former Greenpeace member.

“Anyone who claims that the debate is over and the conclusions are firm has a fundamentally unscientific approach to one of the most momentous issues of our time.” - Solar physicist Dr. Pal Brekke, senior advisor to the Norwegian Space Centre in Oslo. Brekke has published more than 40 peer-reviewed scientific articles on the sun and solar interaction with the Earth.

“The models and forecasts of the UN IPCC "are incorrect because they only are based on mathematical models and presented results at scenarios that do not include, for example, solar activity.” - Victor Manuel Velasco Herrera, a researcher at the Institute of Geophysics of the National Autonomous University of Mexico

“It is a blatant lie put forth in the media that makes it seem there is only a fringe of scientists who don’t buy into anthropogenic global warming.” - U.S Government Atmospheric Scientist Stanley B. Goldenberg of the Hurricane Research Division of NOAA.

“Even doubling or tripling the amount of carbon dioxide will virtually have little impact, as water vapour and water condensed on particles as clouds dominate the worldwide scene and always will.” – Geoffrey G. Duffy, a professor in the Department of Chemical and Materials Engineering of the University of Auckland, NZ

“After reading [UN IPCC chairman] Pachauri's asinine comment [comparing skeptics to] Flat Earthers, it's hard to remain quiet.” - Climate statistician Dr. William M. Briggs, who specializes in the statistics of forecast evaluation, serves on the American Meteorological Society's Probability and Statistics Committee and is an Associate Editor of Monthly Weather Review.

“The Kyoto theorists have put the cart before the horse. It is global warming that triggers higher levels of carbon dioxide in the atmosphere, not the other way round…A large number of critical documents submitted at the 1995 U.N. conference in Madrid vanished without a trace. As a result, the discussion was one-sided and heavily biased, and the U.N. declared global warming to be a scientific fact,” Andrei Kapitsa, a Russian geographer and Antarctic ice core researcher.

“Nature's regulatory instrument is water vapor: more carbon dioxide leads to less moisture in the air, keeping the overall GHG content in accord with the necessary balance conditions.” – Prominent Hungarian Physicist and environmental researcher Dr. Miklós Zágoni reversed his view of man-made warming and is now a skeptic. Zágoni was once Hungary’s most outspoken supporter of the Kyoto Protocol.

“For how many years must the planet cool before we begin to understand that the planet is not warming? For how many years must cooling go on?" - Geologist Dr. David Gee the chairman of the science committee of the 2008 International Geological Congress who has authored 130 plus peer reviewed papers, and is currently at Uppsala University in Sweden.

“Gore prompted me to start delving into the science again and I quickly found myself solidly in the skeptic camp…Climate models can at best be useful for explaining climate changes after the fact.” - Meteorologist Hajo Smit of Holland, who reversed his belief in man-made warming to become a skeptic, is a former member of the Dutch UN IPCC committee.

“The quantity of CO2 we produce is insignificant in terms of the natural circulation between air, water and soil... I am doing a detailed assessment of the UN IPCC reports and the Summaries for Policy Makers, identifying the way in which the Summaries have distorted the science.” - South Afican Nuclear Physicist and Chemical Engineer Dr. Philip Lloyd, a UN IPCC co-coordinating lead author who has authored over 150 refereed publications.

“Many [scientists] are now searching for a way to back out quietly (from promoting warming fears), without having their professional careers ruined.” - Atmospheric physicist James A. Peden, formerly of the Space Research and Coordination Center in Pittsburgh. “All those urging action to curb global warming need to take off the blinkers and give some thought to what we should do if we are facing global cooling instead” - Geophysicist Dr. Phil Chapman, an astronautical engineer and former NASA astronaut, served as staff physicist at MIT (Massachusetts Institute of Technology)

“Creating an ideology pegged to carbon dioxide is a dangerous nonsense…The present alarm on climate change is an instrument of social control, a pretext for major businesses and political battle. It became an ideology, which is concerning.” - Environmental Scientist Professor Delgado Domingos of Portugal, the founder of the Numerical Weather Forecast group, has more than 150 published articles.

“CO2 emissions make absolutely no difference one way or another….Every scientist knows this, but it doesn’t pay to say so…Global warming, as a political vehicle, keeps Europeans in the driver’s seat and developing nations walking barefoot.” - Dr. Takeda Kunihiko, vice-chancellor of the Institute of Science and Technology Research at Chubu University in Japan.

“The [global warming] scaremongering has its justification in the fact that it is something that generates funds.” - Award-winning Paleontologist Dr. Eduardo Tonni, of the Committee for Scientific Research in Buenos Aires and head of the Paleontology Department at the University of La Plata.

“Whatever the weather, it's not being caused by global warming. If anything, the climate may be starting into a cooling period.” Atmospheric scientist Dr. Art V. Douglas, former Chair of the Atmospheric Sciences Department at Creighton University in Omaha, Nebraska, and is the author of numerous papers for peer-reviewed publications.

“But there is no falsifiable scientific basis whatever to assert this warming is caused by human-produced greenhouse gasses because current physical theory is too grossly inadequate to establish any cause at all.” - Chemist Dr. Patrick Frank, who has authored more than 50 peer-reviewed articles.

“The ‘global warming scare’ is being used as a political tool to increase government control over American lives, incomes and decision making. It has no place in the Society's activities.” - Award-Winning NASA Astronaut/Geologist and Moonwalker Jack Schmitt who flew on the Apollo 17 mission and formerly of the Norwegian Geological Survey and for the U.S. Geological Survey.

“Earth has cooled since 1998 in defiance of the predictions by the UN-IPCC….The global temperature for 2007 was the coldest in a decade and the coldest of the millennium…which is why ‘global warming’ is now called ‘climate change.’” - Climatologist Dr. Richard Keen of the Department of Atmospheric and Oceanic Sciences at the University of Colorado.

“I have yet to see credible proof of carbon dioxide driving climate change, yet alone man-made CO2 driving it. The atmospheric hot-spot is missing and the ice core data refute this. When will we collectively awake from this deceptive delusion?” - Dr. G LeBlanc Smith, a retired Principal Research Scientist with Australia’s CSIRO.

Cows to combat global warming!

Scientists are examining cow farts and burps in a novel bid to combat global warming.

Experts said the slow digestive system of cows makes them a key producer of methane, a potent greenhouse gas that gets far less public attention than carbon dioxide.

In a bid to understand the impact of the wind produced by cows on global warming, scientists collected gas from their stomachs in plastic tanks attached to their backs.

The Argentine researchers discovered methane from cows accounts for more than 30 per cent of the country's total greenhouse emissions.

As one of the world's biggest beef producers, Argentina has more than 55 million cows grazing in its famed Pampas grasslands.

Guillermo Berra, a researcher at the National Institute of Agricultural Technology, said every cow produces between 8000 to 1,000 litres of emissions every day.

Methane, which is also released from landfills, coal mines and leaking gas pipes, is 23 times more effective at trapping heat in the atmosphere than carbon dioxide.

Scientists are now carrying out trials of new diets designed to improve cows's digestion and hopefully reduce global warming. Silvia Valtorta, of the National Council of Scientific and Technical Investigations, said that by feeding cows clover and alfalfa instead of grain "you can reduce methane emissions by 25 percent".
