1. Top Ten Things to Know About Global Warming

2. Number Ten There is a scientific consensus that human activities are very likely to affect global climate

3. Number Nine There is some chance that, due to the uncertainties of complex models and the assumptions used to drive them, the consensus is wrong.

4. Number Eight Ignoring the potential implications of climate change is taking a big risk with a valuable asset. –The Intergovernmental Panel on Climate Change (IPCC) recommends that we avoid “dangerous human interference” with global climate systems.

5. Number Seven In order to avoid dangerous interference, IPCC estimates that we need to hold global emissions about steady.

6. Number Six Since the developing world would still like to develop, the developed world must make substantial emissions reductions. –IPCC says 70-80 percent of current levels must be reduced by 2040- 2050.

7. Important Data

8. More Important Data

9. Number Five The Kyoto Protocol will result in only modest emission reductions –The US has not yet ratified this treaty

10. Number Four We have 30-40 years to transform industrialized society –Reducing emissions by 70-80 percent is a substantial challenge

11. US Greenhouse Emissions

12. US CO2 Emissions

13. US Fossil Fuel CO2 Emissions

14. Number Three We already have technologies that can help us on the way –Efficiency –Renewable Energy –Coal-gasification with carbon sequestration

15. Number Two The behavioral challenges are much more daunting than the technological ones.

16. Number One Climate change isn’t likely to affect our generation. We need to make changes for subsequent generations.
