NASA’s Earth Observatory site has a newly updated Global Warming Fact Sheet and Global Warming Q & A.
The Fact Sheet covers the following topics:
- Introduction
- What is Global Warming?
- Evidence for Global Warming
- Building a Climate Model
- Predicting Future Warming
- Potential Effects of Global Warming
The Q & A takes on these questions:
- What does NASA have to do with global warming?
- If Earth has warmed and cooled throughout history, what makes scientists think that humans are causing global warming now?
- Has the Sun been more active in recent years, and could it be responsible for some global warming?
- Haven’t satellites actually observed cooling temperatures in the lower atmosphere?
- Are the ozone hole and global warming related?
- Are the unusual or extreme weather events in my area caused by global warming?
- Are there natural processes that will amplify or limit global warming?
- What if global warming isn’t as severe as predicted?
- Why is global warming a problem?
- If we stabilized greenhouse gas emissions at today’s rates, would global warming stop?
- If we immediately stopped emitting greenhouses gases, would global warming stop?
- What can we do about global warming?
- Where can I learn more about global warming?
