"Stern admits report “badly underestimated” climate change risks"
Latest climate science showed global emissions of planet-heating gases were rising faster and upsetting the climate more than previously thought, Stern said in a Reuters interview on Wednesday.
I guess he has been reading this blog. Everyone should read his report (here). It found that avoiding catastrophic climate change might cost countries 1% of gross domestic product (spent largely on clean energy technologies that have many other benefits such as reductions in urban smog), but failing to act could cost up to 20% of GDP. What else is Stern now saying?
He said that the latest climate science showed that not only were emissions rising faster than thought, the ability of the earth to absorb carbon dioxide in so-called carbon sinks was deteriorating faster than expected.
“Emissions are growing much faster than we’d thought, the absorptive capacity of the planet is less than we’d thought, the risks of greenhouse gases are potentially bigger than more cautious estimates, and the speed of climate change seems to be faster,” he said.
Stern added that to minimise the risks of dangerous climate change, the original target for global emissions would have to be doubled to a 50 per cent cut by 2050. He said that such a target would require the US to cut its emissions by up to 90 per cent by then.
The time to act is, like, so yesterday.
