How telling that the EPA link provided is based on information from 2000. The information in this article is a good layman's reference point for the climate change discussion.

This is an excellent compendium of frequently-asked questions about Global Warming, from the authoritative Union of Concerned Scientists. They provide clear, informative answers, with well-researched links to supporting evidence.

The authoritative presentation of frequently asked questions and short answers is a trifle dry, but straight-forward. The need for information based on facts and data and good scientific analysis is very much in need when massive climate changes may be under way and corporate interests may have an interest in spreading disinformation.

The organization as a Q&A is helpful, but this can be read linearly and it tells the story well. A good amount of evidence, but some points are left a little bare. Contains links to it's sources. These have the needed evidence but you have to search for it. Overall I think this is a good format for opinion journalism. It does not present opposing views such as historical climate change analysis.

This is a good distillation of thousands of people's life work in many scientific disciplines. While it is less journalism in the classic sense than a simplification of a complex scientific report, the information is borad and fair to the best of the scientific community's knowledge. It also does the job of journalism by addressing simply and eloquently a seemingly vast ignorance of this problem.

This is a nice quick read for someone who wants to get the quick and dirty facts about the climate crisis.
