If you do not want to read the following links and discussions, please go back!


Please take a step back, and stay cool for a moment. Shut your ears off from the deafening cries and shouts of the global warming advocates, and sharpen your mind. Try to answer the questions outlined in the papers given hereafter, and be open for good reasoning: these pages might make you think again, and wonder, if the mobiles of all these climate catastrophers are pure .... 

Working for clean air and an unpolluted atmosphere is a laudable aim, but forgetting to compare the magnitude of man-made pollutants to the natural sources, or having an absolute faith in measurement data of often dubious origine, is unscientific at least, and foolish certainly. The climate  is "the changing state of the atmosphere", so do not expect a steady state situation. Do not forget either that the sun is the engine which drives everything, and that the output of that engine is in constant change!

A comment on A caustic comment by Jim Peden, at (search page for Peden). "There is great evil in the Global Warming Hoax. Jim Hansen and Al Gore are not inherently evil persons, but what they have done to spread worldwide panic and a hysterical rush to find a cure for what I and my 32,000 science brethren consider a nonexistent disease, is potentially the greatest calamity in the history of mankind which will lead to starvation for millions, if not billions of people on our planet."

The apocalypse is the scientist’s fundamentalism Lord Robert Skidelsky: "Scientists are notoriously loath to jettison conclusions reached by approved scientific methods, however faulty. But their intolerance of dissent is hugely magnified when they see themselves as captains in a salvationist army dedicated to purging the world of evil habits."
Air pollution by ozone through Europe in Summer 2007 At last, a ray of hope: "Ozone levels during the summer of 2007 were among the lowest in the past decade" says this EEA report. But:  "... the directive's long-term objective to protect human health (maximum c(O3) of 120 μg/m3 over 8 hours) was extensively exceeded in the EU and other European countries. " Not a surprise here: set your maxima impossibly low, and you will be sure to surpass them every year (and have a good argument for more research money!). See meteoLCD  trends!

Others: here
Summary of 2007 Atlantic Tropical Cyclone Activity by Klotzbach & Gray. "Although global surface temperatures have increased over the last century and over the last 30 years, there is no reliable data available to indicate increased hurricane frequency or intensity in any of the globe’s seven tropical cyclone basins besides the Atlantic"
Shortwave Forcing of Earth's Climate A new (2007) important paper by Goode & Pallé on modern and historical variations in the Sun’s irradiance and the Earth’s reflectance: " the Earth’s large scale reflectance... is a much more variable climate parameter than previously thought" " The decrease in the Earth’s reflectance from 1984 to 2000 ... translates into a Bond albedo decrease of 0.02 (out of the nominal value of about 0.30) or an additional global shortwave forcing of 6.8W/m2... IPCC, 2001 argues for a 2.4W/m2 increase in CO2 longwave forcing since 1850".

Christie/Spencer record of satellite data "The Christy/Spencer record begins in January 1979 and is updated monthly. According to a just-published paper (Christy et al, 2003), the global temperature trend in the lower atmosphere from earth’s surface to about 25,000 feet is 0.06ºC (±0.05ºC per decade) from January 1979 through April 2002. This trend has enormous implications because it invalidates the projections of virtually every climate model in existence!"

The Gobal Warming pages of this "general purpose skeptic" site.

Center for the Study of Carbon Dioxide and Global Change: very scientific, many reports, mailing-list
Torturing Climate Statistics A well written paper by John Daly, downloaded from his web-site (Dec.2001)
 Disaster, Failure or Success? "I interpret the IPCC, as far as its advisory capacity is concerned, as a mixed group of self-selected believers and officially selected experts, most of them paid directly by governments, who do not, indeed cannot, give entirely honest advice". An excellent paper by an IPCC insider!
Controverses scientifiques sur l’effet de serre A well written paper from Pierre Lutgen (Luxembourg), with a large list of references (in french)

This certainly is the best start for a sceptical voyage to the political motives and scientific methods of the global change industry. (+John Daly from Tasmania)
John Daly passed away the 29th Jan. 2004. We will deeply miss his clear logic and courage in pursuing scientific honesty versus ideology and Zeitgeist.
