3-4 Degrees Celsius: Looking Grim

Humans could escape in scenarios where only 10 to 20 percent of
species go extinct. We would likely be reduced in number but
plausibly still do OK at a 30 percent extinction rate.
But as the evidence points toward “up to 50 percent” extinction rate,
we should expect very serious trouble for ourselves.

There has been broad, strong consensus in the climate science
community that we’d better avoid a warming of 2C (2 Celsius) above
today.

of optimism to hold on to. If by Copenhagen it hasn’t been addressed
then it will look very bleak indeed.”
