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].

Two things can be true at the same time:

1. significantly increased amount of 'life' on earth (as in: total kg of biomass, number of living specimens, total area with some amount of green stuff on it) due to warmer climate.

2. significantly reduced number of extant species on earth due to (geologically) fast changes in climate.
