I know this post is specifically about global warming, but I thought I'd talk about climate change and conservation in general. We are at the point of no return for climate change in my opinion. I just don't see a global will to enact the kind of change which would be required to reverse this. Tiger populations have decreased from an estimated 100,000 at the start of the 20th centry to around 3000. Lion populations have decreased 30-50% in the last few decades alone. ([1] and [2]). I fear that we will see these, and many more iconic species go extinct in our lifetime. I'm sure this has been discussed before, but the ice-melt could precipitate a "Day after Tomorrow" kind of event, with the warm currents changing course [3].
