RealClimate is a blog run by 11 of the world's top climate scientists. The posts are typically updated twice per week, and invariably cover the latest breaking research, political happenings, and attacks by global warming skeptics. There is no better way to stay informed on climate change than to become a regular reader of RealClimate. Start with their index of topics, which has wealth of infomation on all the important aspects of climate change. Many of the links below were taken from a RealClimate post.

The UN Intergovenmental Panel on Climate Change (IPCC) publishes an huge climate summary every six years that is the most authoritative and widely quoted study on climate. For those with a basic familiarity with climate change, be sure to read the 2007Summary for Policy Markers. For those not familiar with climate change, read the Frequently Asked Questions section of the IPCC 4th report, issued in 2007 in (pdf) form. It covers:

• What Factors Determine Earth's Climate?
• What is the Relationship between Climate Change and Weather?
• What is the Greenhouse Effect?
• How do Human Activities Contribute to Climate Change and How do They Compare with Natural Influences?
• How are Temperatures on Earth Changing?
• How is Precipitation Changing?
• Has there been a Change in Extreme Events like Heat Waves, Droughts, Floods and Hurricanes?
• Is the Amount of Snow and Ice on the Earth Decreasing?
• Is Sea Level Rising?
• What Caused the Ice Ages and Other Important Climate Changes Before the Industrial Era?
• Is the Current Climate Change Unusual Compared to Earlier Changes in Earth's History?
• Are the Increases in Atmospheric Carbon Dioxide and Other Greenhouse Gases During the Industrial Era Caused by Human Activities?
• How Reliable Are the Models Used to Make Projections of Future Climate Change?
• Can Individual Extreme Events be Explained by Greenhouse Warming?
• Can the Warming of the 20th Century be Explained by Natural Variability?
• Are Extreme Events, Like Heat Waves, Droughts or Floods, Expected to Change as the Earth's Climate Changes?
• How Likely are Major or Abrupt Climate Changes, such as Loss of Ice Sheets or Changes in Global Ocean Circulation?
• If Emissions of Greenhouse Gases are Reduced, How Quickly do Their Concentrations in the Atmosphere Decrease?
• Do Projected Changes in Climate Vary from Region to Region?
