Global warming typifies an environmental problem that transcends borders. This portal from the United Nations Environment Programme is a good starting point for scientists, policy-makers, and neophytes looking for information on climate change. Readers can browse a slew of reports from the U.N. and other organizations that tally the evidence that carbon dioxide (CO2) and other humanmade gases are contributing to global warming and probe its possible consequences on health, forests, and biodiversity. If you're baffled by climate change lingo, check out the glossary in six languages.

Researchers hankering for data on global change can troll this compendium from Oak Ridge National Laboratory in Tennessee. Scores of key data sets range from monthly CO2 emissions from fossil fuel use around the world to temperature records for the last 2000 years based on Antarctic ice cores. You can also peruse the famous CO2 measurements from Mauna Loa, Hawaii, where soaring levels since 1958 first brought the greenhouse gas buildup to scientists' attention.
