Since many of the environmental issues of the day are likely to be affected by climate change, this site offers selected resources to help you inform yourself about Earth's current condition. The resources listed below are offered by Dr. Ellen Mosley-Thompson, a climatologist at Ohio State, when she gives presentations to the public.
She wrote: "The following information is provided for those who wish to learn more about this issue [climate change]. These materials are organized from the most basic information to more complex issues. Included are a number of the international and national assessments that represent the general scientific consensus on specific topics. It is important to remember that scientists are naturally skeptical and constantly test and retest their hypotheses as more observations are obtained and as knowledge advances. Climate science, like all the sciences, builds on current knowledge to generate deeper and broader understanding."
Ellen also explains some terms that are frequently used, as a helpful starting point:
"Below are some websites where you can explore the fundamentals of the role of greenhouse gases in maintaining Earth's energy balance, and the role of additional greenhouse gases that result in an enhanced warming." The latter is greater than the natural greenhouse effect (GHE) and is "...called the enhanced greenhouse effect, which is often cited as a mechanism contributing to 'global warming'. Global warming is a catch-all term that really means the globally-averaged surface temperature (GAST) of Earth has warmed. The best estimate is that the GAST has increased about 0.75 degrees C. since 1900."
