I think most folks would agree with that. However, there is considerable room for debate about:
- the speed of the warming since much of the historical data has been doctored or was unreliable
- the hubris of progressive elites in thinking that we can somehow change or control the climate by spending billions and billions of dollars of other people's money...a TOTALLY unproven theory
Many of Al Gore's claims in Inconvenient Truth have already fallen flat on their face.
My guess is that everyone is for responsible environmental management. Where opinions collide is when there are expensive over-the-top solutions being proposed when it is completely unclear if they will work or to what degree they will work.
It may be far, far cheaper to have mankind simply react to climate change as it actually occurs. If sea levels do indeed rise and a few islands are no longer habitable....move. That is a lot cheaper than trying to build sea walls which will likely fail anyway. Ocean levels have risen and fallen over eons already, and they will continue to do so no matter what mankind does.
To me, the biggest cause of climate change is over-population. And NO ONE is willing to take on that topic.
