What exactly is your understanding of climate change and the science indicating and supporting such?
I'm far, far from an expert (or even mildly educated). I am a chemical engineer, so at least I understand some of the words.
I'm pretty close to Thayer School of Engineering at Dartmouth (an overseer), and I respect many people there. I don't know of one Thayer person who denies Global Warming. In fact, it's pretty much assumed, worrisome, and deserving substantial effort. It's one of our three strategic priorities at the school. (They have data and knowledge. I don't.)
While certainly I would not stake my life on Wikipedia, the GW articles there are quite convincing. One of the most interesting facts is that whereas GW largely is acknowledged in most countries, the American public has become surprisingly skeptical (a little over half the population no longer views it as a serious concern). This is a bit dismaying, since apparently scientists by-and-large have a completely different view:
Wikipedia: "The scientific consensus is that global warming is occurring and is mostly the result of human activity. This finding is recognized by the national science academies of all the major industrialized countries and is not rejected by any scientific body of national or international standing."
I'm sure there are quotable scientists who take the opposite view; although I worry that they may not represent the majority. (I hope that Rush Limbaugh knows what he is talking about, because he is influential.) And again, I do not swear by Wikipedia, although it's usually pretty good in my experience.
One sound-bite that really resonates with me is the story of the Norwest Passage. It's a compelling anecdote:
Wikipedia: "Sought by explorers for centuries as a possible trade route, it was first navigated by Roald Amundsen in 1903–1906. Until 2009, the Arctic pack ice prevented regular marine shipping throughout most of the year, but climate change has reduced the pack ice, and this Arctic shrinkage made the waterways more navigable."
The opening of the Northwest Passage (stuff of fables, literally) is pretty scary.
Finally, my friends who live in Alaska (and/or have visited Alaska) are totally convinced about GW, without exception. Admittedly, it's hearsay, but these are by no means dyed-in-the-wool, liberal, tree-hugging idiots. In fact, most of them are ardent republicans!
Sorry, none of this is hard data, but it's the best I've got...
Again, my position is to act as though Global Warming
might be true.
Thank you very much for asking!
