This is what the American Geophysical Union has to say concerning global warming;

AGU Revises Statement on Global Warming | Desert News

Following is the text of the revised statement, entitled “Human Impacts on Climate.”

The Earth’s climate is now clearly out of balance and is warming. Many components of the climate system – including the temperatures of the atmosphere, land and ocean, the extent of sea ice and mountain glaciers, the sea level, the distribution of precipitation, and the length of seasons – are now changing at rates and in patterns that are not natural and are best explained by the increased atmospheric abundances of greenhouse gases and aerosols generated by human activity during the 20th century. Global average surface temperatures increased on average by about 0.6 degrees Celsius over the period 1956-2006. As of 2006, eleven of the previous twelve years were warmer than any others since 1850.


The observed rapid retreat of Arctic sea ice is expected to continue and lead to the disappearance of summertime ice within this century. Evidence from most oceans and all continents except Antarctica shows warming attributable to human activities. Recent changes in many physical and biological systems are linked with this regional climate change. A sustained research effort, involving many AGU members and summarized in the 2007 assessments of the Intergovernmental Panel on Climate Change, continues to improve our scientific understanding of the climate.

During recent millennia of relatively stable climate, civilization became established and populations have grown rapidly. In the next 50 years, even the lower limit of impending climate change – an additional global mean warming of 1 degree Celsius above the last decade – is far beyond the range of climate variability experienced during the past thousand years and poses global problems in planning for and adapting to it. Warming greater than 2 degrees Celsius above 19th century levels is projected to be disruptive, reducing global agricultural productivity, causing widespread loss of biodiversity, and – if sustained over centuries – melting much of the Greenland ice sheet with ensuing rise in sea level of several meters. If this 2 degrees Celsius warming is to be avoided, then our net annual emissions of carbon dioxide must be reduced by more than 50 percent within this century. With such projections, there are many sources of scientific uncertainty, but none are known that could make the impact of climate change inconsequential. Given the uncertainty in climate projections, there can be surprises that may cause more dramatic disruptions than anticipated from the most probable model projections.

Now, would any care to present a statement from a scientific society that say that AGW is not a fact? How about a National Academy of Science? Even from Outer Slobovia? A major University?

Come on people, surely you can do that? I can fill the page with those that state that AGW is a fact, and a clear and present danger. Can you present even one of these organizations that says otherwise? Or are you just shilling for the political arms of the present energy companies.

Meaningless news program. I am not an AGW proponent and I can see that. Come up with more...

According to the data produced from various scientists from various institutions, we are not warm beyond any reasonable person's ideas.

In truth, their work indicates that we are below average for the temperatures experienced in this intergalcial measuring the proxies that you are fond of pointing to.

When you call attention to receeding glaciers and to temperature bands moving northward, you are measuring what the chart in the link below measures. Those proxies are showing today that we are about in the middle of a range of temperature enjoyed for 10,000 years.
