Scientific Consensus on Global Warming

I also want to repeat this from last year. Around October of 2009, a coalition of 18 major scientific organizations (these are really big ones...some of the biggest in the country) issued this statement (PDF) to the Senate:

Dear Senator:

As you consider climate change legislation, we, as leaders of scientific organizations, write to state the consensus scientific view.

Observations throughout the world make it clear that climate change is occurring, and rigorous scientific research demonstrates that the greenhouse gases emitted by human activities are the primary driver.

These conclusions are based on multiple independent lines of evidence, and contrary assertions are inconsistent with an objective assessment of the vast body of peer-reviewed science. Moreover, there is strong evidence that ongoing climate change will have broad impacts on society, including the global economy and on the environment. For the United States, climate change impacts include sea level rise for coastal states, greater threats of extreme weather events, and increased risk of regional water scarcity, urban heat waves, western wildfires, and the disturbance of biological systems throughout the country. The severity of climate change impacts is expected to increase substantially in the coming decades. [See Footnote #1 below]

If we are to avoid the most severe impacts of climate change, emissions of greenhouse gases must be dramatically reduced. In addition, adaptation will be necessary to address those impacts that are already unavoidable. Adaptation efforts include improved infrastructure design, more sustainable management of water and other natural resources, modified agricultural practices, and improved emergency responses to storms, floods, fires and heat waves.

We in the scientific community offer our assistance to inform your deliberations as you seek to address the impacts of climate change.


1 The conclusions in this paragraph reflect the scientific consensus represented by, for example, the Intergovernmental Panel on Climate Change and U.S. Global Change Research Program. Many scientific societies have endorsed these findings in their own statements, including the American Association for the Advancement of Science, American Chemical Society, American Geophysical Union, American Meteorological Society, and American Statistical Association.

The following societies signed this statement:

* American Association for the Advancement of Science
* American Chemical Society
* American Geophysical Union
* American Institute of Biological Sciences
* American Meteorological Society
* American Society of Agronomy
* American Society of Plant Biologists
* American Statistical Association
* Association of Ecosystem Research Centers
* Botanical Society of America
* Crop Science Society of America
* Ecological Society of America
* Natural Science Collections
* Alliance Organization of Biological Field Stations
* Society for Industrial and Applied Mathematics
* Society of Systematic Biologists
* Soil Science Society of America
* University Corporation for Atmospheric Research

The scientific consensus regarding global warming is overwhelming. It is time for the denial lobby to shut up. I recommend all my readers forward the above statement to their Congress critters. And let me add another list, taken from Daily Kos, showing the overwhelming scientific agreement on global warming. The following groups say the danger of human-caused climate change is a ... FACT:
