[Do browse and observe. While some of the work here may
be perfectly valid scientifically, not all is trustworthy,
because it is all overlighted by a dogmatic belief in Anthropogenic
Global Warming, "proved" by selection and omission
of evidence. The courtesy towards skeptics and doubters can
often be seen to fall short; and one does not even see here
the huge number of perfectly reasonable scientific posts that
have been censored, for no other reason than that they seriously
challenge the AGW dogma - GWT]

Warming FAQ (Tom Rees)
Those with some knowledge:
The IPCC AR4 Frequently Asked Questions (here)
is an excellent start. That 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
- How Reliable Are the Models Used to Make Projections
of Future Climate Change?
- Can Individual Extreme Events be Explained by Greenhouse
- Can the Warming of the 20th Century be Explained by Natural
- 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?
