Greenhouse gases, oceans, snow and ice, society and ecosystem are covered. Some of the key findings include...
- Greenhouse gas emissions from human activities are increasing. Between 1990 and 2008, there has been about a 14 percent increase in emissions in the United States.
- Average temperatures are rising. Seven of the top 10 warmest years on record for the continental United States have occurred since 1990.
- Tropical cyclone intensity has increased in recent decades. Six of the 10 most active hurricane seasons have occurred since the mid-1990s.
- Sea levels are rising. From 1993 to 2008, sea level rose twice as fast as the long-term trend.
- Glaciers are melting. Loss of glacier volume appears to have accelerated over the last decade.
- The frequency of heat waves has risen steadily since the 1960s. The percentage of the U.S. population impacted by heat waves has also increased.
The nicest thing about the report in my opinion is that it's not stuffed with text only. Colorful images and graphs make up a large bulk of the report and topics are broken up sufficiently, both of which makes for easy reading as compared to some reports.
