What is the most reliable source of scientific information on global warming?
We recommend the reports from the Intergovernmental Panel on Climate Change (IPCC). The IPCC was established in 1988 to examine the most current scientific information on global warming and climate change. The IPCC does not carry out research. Rather, the IPCC reviews all of the published and peer-reviewed scientific information produced in recent years to assess what we know about the global climate, why and how it is changing, what it means for people and the environment, and what can be done about it. Over 1,250 authors and 2,500 scientific expert reviewers from more than 130 countries contributed to the IPCC’s most recent report, Climate Change 2007: The Fourth Assessment Report. Because the IPCC strives to achieve consensus among a very large group of authors, it tends to be conservative in its conclusions. Nonetheless, it serves a critical role as a consolidator of information from the whole spectrum of climate change science.
