From the official website of NASA, for all of the denialists “skeptics” out there:
Ninety-seven percent of climate scientists agree that climate-warming trends over the past century are very likely due to human activities,and most of the leading scientific organizations worldwide have issued public statements endorsing this position. The following is a partial list of these organizations, along with links to their published statements and a selection of related resources.
Statement on climate change from 18 scientific associations
“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.” (2009)
American Association for the Advancement of Science
“The scientific evidence is clear: global climate change caused by human activities is occurring now, and it is a growing threat to society.” (2006)
American Chemical Society
“Comprehensive scientific assessments of our current and potential future climates clearly indicate that climate change is real, largely attributable to emissions from human activities, and potentially a very serious problem.” (2004)
American Geophysical Union
“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.” (Adopted 2003, revised and reaffirmed 2007)
American Medical Association
“Our AMA … supports the findings of the Intergovernmental Panel on Climate Change’s fourth assessment report and concurs with the scientific consensus that the Earth is undergoing adverse global climate change and that anthropogenic contributions are significant.” (2013)
American Meteorological Society
“It is clear from extensive scientific evidence that the dominant cause of the rapid change in climate of the past half century is human-induced increases in the amount of atmospheric greenhouse gases, including carbon dioxide (CO2), chlorofluorocarbons, methane, and nitrous oxide.” (2012)
American Physical Society
“The evidence is incontrovertible: Global warming is occurring. If no mitigating actions are taken, significant disruptions in the Earth’s physical and ecological systems, social systems, security and human health are likely to occur. We must reduce emissions of greenhouse gases beginning now.” (2007)
The Geological Society of America
“The Geological Society of America (GSA) concurs with assessments by the National Academies of Science (2005), the National Research Council (2006), and the Intergovernmental Panel on Climate Change (IPCC, 2007) that global climate has warmed and that human activities (mainly greenhouse‐gas emissions) account for most of the warming since the middle 1900s.” (2006; revised 2010)
Then again, to the conspiracy theorist, NASA is just part of this conspiracy to fake climate change for some reason. After all, according to the conspiracy theorist, they also faked the moon landing for some reason. (I dunno, maybe their evil plan is to convince people to buy LED lightbulbs and hybrid cars without needing them.)
