After assessing and reviewing countless reports from scientists all over the world, the IPCC notes that “scientific evidence for warming of the climate system is unequivocal.” Their evidence?

In a brief summary: Ice sheets have shrunk and glaciers are retreating. Ocean temperatures and sea levels have risen. The acidity of ocean water has increased dramatically over the last century due to elevated carbon dioxide levels in the atmosphere. Precipitation patterns have changed. Global temperatures have risen.

A guide compiled by ThinkProgress includes summaries of the most significant reports on climate science. They include reports by the IPCC. Some of the most meaningful data presented by the reports are the following: levels of carbon dioxide in the world are the highest they have been in 15 million years; the oceans are acidifying ten times faster today than 55 million years ago when a mass extinction of marine species occurred; and temperatures on land have risen to the highest they have ever been on record.
