And then they say:There's good news! And there's also bad news.
The good news is that the "worst-case" scenario of 6C degrees rise of global temperature was an exaggerated risk in the first place and due to improvements in the relevant risk factors, this worst case ending is now unlikely to occur.
The bad news is that we're still on course for 3-4C degrees of global temperature rise, and that recent research shows the earth is even more sensitive to CO2 than previously realized, so that 3C degree is not a picnic in the park scenario. It will be quite bad enough, tyvm. And 4C degree would also not be any fun at all.
So, the takeaway is that in 2020, a grim future is seen as good news.
Climate change: Worst emissions scenario 'exceedingly unlikely'
Referred to as "business as usual", the worst-case scenario for CO2 emissions this century is no longer plausible, say researchers.www.bbc.com
“There is also the question of climate feedbacks. Although emissions from human activities might level off over this century, warming could see more permafrost melt which will push more methane and CO2 into the air, putting upward pressure on temperatures.”
They don’t mention ocean acidification and warming.
It’s great renewables are cheaper (and I hope we switch over completely) but the current powers that be, are still supporting fossil fuel industries.
I feel quite nervous.
