And then we’re completely doomed, unlike all the other tipping points. This one matters, you guys!
(9News) 6.6.16 is almost the devil’s number, but it might be much more than that if a leading scientist’s prediction on climate change is correct.
CSIRO fellow Dr Paul Fraser has earmarked June 6 (“plus or minus a week”) as the day when carbon dioxide concentration in the atmosphere will hit the point of no return, 400 parts per million (ppm).
The atmospheric measuring station at Cape Grim in Tasmania has recorded the current C02 levels in the atmosphere at 399.9ppm.
Dr Fraser said the difference between 399 and 400ppm was trivial, but when it does hit 400ppm mark it would be a “psychological tipping point”. (snip)
When 400ppm becomes the norm in country air, the cities will feel the pain a whole lot more.
