I love irony.
The United States National Academy of Sciences (along with several other national science academies),per global warming:
There is now strong evidence that significant global warming is occurring. The evidence comes from direct measurements of rising surface air temperatures and subsurface ocean temperatures and from phenomena such as increases in average global sea levels, retreating glaciers, and changes to many physical and biological systems. It is likely that most of the warming in recent decades can be attributed to human activities. This warming has already led to changes in the Earth's climate... Increasing greenhouse gases are causing temperatures to rise... The scientific understanding of climate change is now sufficiently clear to justify nations taking prompt action.
