I no longer worry. I'm extremely pessimistic about the impending climate change. I believe Sabine isn't pessimistic enough about what to anticipate. Consider the tundra methane emissions and the explosive release of methane-hydrates from the oceans, along with water vapor, a potent greenhouse gas. The disaster looming over all ecosystems (a mass extinction event) that will happen in decades and the doom-phase could last for 200,000 years. The chances of humanity surviving are incredibly slim, IMO. We can't colonize Greenland or Antarctica due to the lack of fertile soil, and it would take thousands of years to develop it. Without saying so, we don't have this amount of time.

There won't be an extinction event. We already know that warm periods in Earth's history are the most friendly for all kinds of life. And we know that cold periods kill species and reduce biodiversity. In the most catastrophic case Earth will end up as a tropical paradise, resembling the Eocene period [0].

This is naive. It's not the absolute temperature that's the problem, it's the rate of change. Temperature is going to change faster than most species can adapt, and that's why the food chain could collapse in the worst case.

>>naaski+8e2
That's true, but I think it's quite debatable what would actually happen. Most species wouldn't need to adapt, but just migrate. There are a lot of species which already thrive in warm / tropical climates, and those species would increase in numbers.

This all will absolutely disrupt agriculture and food chains. Also humans are political creatures which cannot easily migrate. These migrations usually end up with things, called wars.
