1. Global Warming Is Real By: Dalton Lightner, Stephanie Burke, Joseph Cave

2. Global warming is the increase in the average temperature in the Earth’s near surface air and ocean since the mid-20th century

3. Studies of polar bears have reviled that not only have their numbers declined by nearly one quarter, in just 20 years to around 25,000 but so has their physique.

4. There was a case made that man’s actions in burning fossil fuels are projected to increase the concentration of carbon dioxide in the atmosphere to the highest levels in history.

5. The strongest evidence that global warming has been triggered by human activity has emerged from a major study of rising temperatures in the worlds oceans.

6. Global sea level rose about 17 centimeters (6.7 inches) in the last century. The rate in the last decade, however, is nearly double that of the last century

7. Both the extent and thickness of Arctic sea ice has declined rapidly over the last several decades

8. The number of record high temperature events in the United States has been increasing, while the number of record low temperature events has been decreasing, since 1950. The U.S. has also witnessed increasing numbers of intense rainfall events.

9. The carbon dioxide content of the Earth’s oceans has been increasing since 1750, and is currently increasing about 2 billion tons per year. This has increased ocean acidity by about 30 percent

10. Glaciers are starting to melt and the sea level is starting to rise.

11. The earth is getting warmer. Both the air at the surface of the Earth and the Earth’s surface itself and it is warming much faster than any natural variation.

12. 10 of the warmest years occurring in the past 12 years.
