I imagine their parents are quite proud of them.

Nobody is asking you to take Castro's word on climate change. Picking out someone you don't like and thinking that discredits something he believes in along with millions of others makes no sense. The fact that Trump is a climate change denier would not be enough to discredit climate change denial.

It's not a religion. It's based on data, not faith. Global warming and climate change are terms that have co-existed pretty much from the beginning. They describe two related but different things - global warming causes climate change. The name wasn't changed by some mysterious "them" to account for variations in weather. In fact, the only known instance of anyone urging the use of the term climate change instead of global warming is Republican strategist Frank Luntz during the Bush presidency. In a memo designed to help candidates to justify the party position at the time, he wrote that climate change was a less frightening term than global warming and so that should be the term they used.

Here endeth the lesson. Darn - I just undermined my contention that it's not a religion. smile
