Global warming is occurring. However, global warming is also occurring on Mars, and sunspot activity is at or near a very long-term high. One question we should be asking is what percentage of global warming is due to increased human activity, and what percentage of global warming is due to increased sun activity.

It's amazing what a well-run campaign to muddy the waters can do. Anyone who thinks there is not consensus among 99% of scientists (the ones not on the take, or with a political agenda) is failing as a human being.

Edited to add: anyone who thought there was not consensus within the scientific community about global warming (I'm counting a few of you just in this thread) needs to find an honest source of news.
