Summarized here you will find, verbatim, the 18 consensus conclusions of two recent “state of knowledge” scientific reports on global warming and climate change.
Global Climate Change Impacts in the United States (2009) -Full Report . Presenting the latest scientific consensus report on U.S. climate change impacts, this report by the U.S. Global Change Research Program presents inter-agency findings by a long list of experts enlisted by the U.S. Government. (Cited here as “US Impacts, 2009”)
Copenhagen Diagnosis Updating . . . the Latest Global Climate Science (2009) – Full Report . Written for policy-makers, stakeholders, the media and the broader public, this report aims to synthesize the most policy-relevant climate science. It relies on the 100s of papers published since the editorial cut-off for the Nobel-Prizing-Winning “Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4) (2007).” All quotes below from this report are from the “Executive Summary,” pg. 7.

18 Key Conclusions
(Click underlined titles to view, or scroll down to read any or all)
1. Primarily human caused, global warming stands proven.
2. Recent global temperatures demonstrate the role of humans in creating global warming.
3. Greenhouse gas emissions surge.
4. As with many other countries, the United States experiences present climate changes -- and projects that they will grow.
5. Acceleration of melting ice-sheets, glaciers and ice-caps.
6. Rapid Arctic sea-ice decline
7. Current sea-level rise underestimated.
8. Sea-level predictions revised.
9. Widespread climate-related impacts occur now -- and will likely increase.
10. Water sources stressed by climate change.
11. Crop and livestock production challenged by climate change.
12. Human health risks increase.
13. Many social and environmental stresses made worse by climate change.
14. Coastal areas face increasing risk from the rise of sea-levels and storm surges.
15. Climate-related events will cross thresholds leading to large changes in both climate and ecosystems.
16. Delaying action could trigger “tipping points” and risk irreversible damage.
17. The turning point must come soon.
18. Future climate change and its impacts depend on choices made today.
Global annual average temperature, measured over both land and oceans.
Red bars indicate temperatures above, and blue bars indicate temperatures below, the average temperature for the period 1901-2000.
The black line shows atmospheric carbon dioxide (CO2) concentration in parts per million (ppm).
