Re: doom and gloom, I'm less worried about the immediate effects of climate change than I am about the knock-on effects. By which I mean wide scale war. For example, large areas in India (and other hot, humid places) may see lethal wet bulb temperatures during heatwaves within a few decades. I'm not looking forward to seeing how things play out when nuclear powers like India and Pakistan have to deal with hundreds of millions of their citizens needing to relocate.
