For what its worth, IS92-A is a bit above RCP6.0, which is in the range of outcomes consistent with current policies. We are far from bending down the curve though, which is whats needed to get to below-2C.pic.twitter.com/ON6mFJuTl4
First read this as a (good) joke. Which geopolitical success exactly? Are y'all following the news & geopolitics at all?
It seems like energy markets have dominated these changes rather than top down controls/policies?
Do you think that this would have happened in the absence of people highlighting the risks associated with climate change?
As an *emissions* pathway 8.5 has become highly unlikely, we are told. But as a *concentration* pathway (it's in the name, RCP) does our optimism not depend on feedbacks about which there is far more uncertainty?
Yes. However, if the emission projections are reasonable, then the feedbacks required to get to 8.5W/m^2 are probably now on the higher end of what is possible. However, could still turn RCP6 into RCP7, for example.
Hi Mark. My understanding is 2 or 3 degrees at 2100 is very dangerous because it is unlikely to stablise at this point, and could lead to uncontrolled temperature increase. Is this wrong? @medialens @GreenRupertRead
In all of Earth history we have no evidence of runaway global warming. We have evidence of sharp rapid rises in global temperatures but never runaway. So we have to balance the real scary science with the apocalyptic views of some activist - who try to scary children!
Which policies? You mean emission trading scheme?
Does make some rich
