→The modern warm period: A reporter for the ''Chicago Tribune'' called the IPCC "the top body of climate change scientists in the world".
A [[United Nations]] panel ([[IPCC]]) asserts that most of the warming since around 1850 is human-caused. Liberals call this panel "authoritative". Conservatives question its objectivity, and a handful of scientists have resigned from the panel in protest over unauthorized changes in scientific reports.

In February, 2007, the politicized [[IPCC|Intergovernmental Panel on Climate Change]], a body of scientists<ref>http://www.chicagotribune.com/news/nationworld/chi-0704280477apr29,1,4275902.story?coll=chi-newsnationworld-hed</ref> established by the [[United Nations]], but whose members were appointed by their governments, released their fourth assessment report on climate change. That report concluded that most of recent global warming was "very likely" caused by human activity<ref>http://news.bbc.co.uk/2/hi/science/nature/6321351.stm</ref>. It says that increases in atmospheric concentrations of [[greenhouse gas]]es cause warming. Several members of this panel later complained their contributions were misrepresented in the final report.
