thousand year run

The Australian of the Year, the scientist Tim Flannery, said the highest temperature forecasts could spell disaster for many species.

“[It] lays out a sort of middle-of-the road trajectory, which is alarming enough, I can tell you, for this century,” Professor Flannery said. “Three degrees will be a disaster for all life on Earth. We will lose somewhere between two out of every 10 and six out of every 10 species living on the planet at that level of warming.”

“It will set in train a series of climate consequences that will run for a thousand years.”
