Global warming milestone about to be passed and there’s no going back

Within the next couple of weeks, a remote part of north-western Tasmania is likely to grab headlines around the world as a major climate change marker is passed.
The aptly named Cape Grim monitoring site jointly run by CSIRO and the Bureau of Meteorology will witness the first baseline reading of 400 parts per million (ppm) of carbon dioxide in the atmosphere, researchers predict.

“Once it’s over [400 ppm], it won’t go back,” said Paul Fraser, dubbed by CSIRO as the Air Man of Cape Grim, and now a retired CSIRO fellow. “It could be within 10 days.”

That second one is terrifying. $0.02 on us breaking the +1.5 °C mark this summer.

I have only one word: FUCK.
