@Ryuko_Izayoi @ShakerMaker123 @ScottyGoesAgain No. Global av temp should have declined in the last 5,000 years. But it has not. We may well have shifted the Earth from icehouse to hothouse, ie ended the ice age. Too early to be sure. If temp increases anot

@MartinJBern @_ClimateCraze What I said was if we go past 2, feedbacks kick in and eventually take us to 8. This would take thousands of years. Your graph shows the general long term trend, it doesn't show little ups and downs over a few thousand years. ht
@petite_michelle The scenario that is keeping some climate scientists awake at night is "Hothouse Earth". There are 'tipping points' of our Earth's climate system that, if we go past them, there is NO RETURN to how it was. PNAS paper here: https://t.co/zUr

@jwipson80 @MrJackLowe That is very long term scenario. There is already 50% more CO2 than is natural for an interglacial. Last time there was this much was 11 million years before the ice age started, not counting a bit of ice on Antarctica. https://t.co/

@HSmith24993512 @latimeralder CO2 might stop it. It depends how fast the earth can absorb it, how much more we emit, how much feedbacks kick in. Once we go past 2° we are most likely on this route: https://t.co/es3tKvMNk3 https://t.co/e1VpxP6KX1

@lastsaskliner @ChrisMartzWX 1.9° warming is pretty bad. But I've no doubt it will happen. I think it will go higher than that. Think is, above 2° feedbacks are more likely, amplifying warming, no way back, heading to eventual 8° in theory. https://t.co/es
