3. In order to estimate temperatures of the past, scientists analyze proxy indicators such as tree rings, ice cores, and ocean sediment.

4. A F where to get cheap michael kors bags rench mathematician, Jean Baptiste Joseph Fourier, was the first to recognize a gradual warming of Earth in 182 where to get cheap michael kors bags 4.

5. Fourier developed a theory, later coined the greenhouse effect by Nobel laureate Svante Arrhenius, arguing that Earths atmosphere traps heat from the sun and reflects it back to Earth. Arrhenius added in the late 1800s that changes in carbon dioxide leve where to get cheap michael kors bags ls contributed to the effect.

6. The average temperature of Earths surface has increased by approximately 1.4 degrees Fahrenheit in the past 100 years.

7. Scientists predict that the temperature will rise between 2 degrees Fahrenheit and 11 degrees Fahrenheit by 2100.

8. The eight warmest years recorded have all been after 1998. The warmest year to date was 2005.

9. Climate change could cause a rise in sea levels, extreme weather conditions, and the incidence of tropical diseases such as malaria, experts say.

10. Most scientists believe that the proliferation of greenhouse gases caused by human activity is responsible for recent climate change. Others disagree, claiming that natural processes such as increases in the suns output or volcanic eruptions are most to blame. On a planet whose climate has varied immmeasurably over its history, from a virtual block of ice to a steam bath and everywhere in between, it seems to detract from the certainty with which Gore and colleagues predict a dire future based on their tiny scraps of data.

Its still a bit amazing to me how politicized this issue is. On the left you hear from pundits like Rachel Maddow and Bill Maher, for whom global warming is a fact, and all human caused. No doubt about it, and youre an idiot if you dont believe it. I swear, I think its the agnostics religion. Then on the right, you have Linbaugh, Beck, and others who poopoo the entire notion, and hold up their esteemed experts to prove their side. Kind of makes a guy wondering who all the experts really are, whats in it for them Al Gore, and what the truth is. where to get cheap michael kors bags
