Flere intenst dårlige nyheter: Ny studie fra en gruppe med respekterte klimaforskere som spør om to graders oppvarming er "trygt". https://www.theguardian.com/environ...events-could-push-earth-into-a-hothouse-state
Deres forsiktige svar er at det er en veldig god sjanse for at to grader ikke er trygt - at det vil sette i gang selvgående mekanismer som får oss til fire graders oppvarming (noe som ville være apokalyptisk, såvidt jeg kan forstå). Slik jeg skrev litt lenger opp: Dette dreier seg ikke om å "tenke på miljø". Det dreier seg om vår fuckings overlevelse.
"Their new paper asks whether the planet’s temperature can stabilise at 2C or whether it will gravitate towards a more extreme state. The authors attempt to assess whether warming can be halted or whether it will tip towards a “hothouse” world that is 4C warmer than pre-industrial times and far less supportive of human life.
Katherine Richardson from the University of Copenhagen, one of the authors, said the paper showed that climate action was not just a case of turning the knob on emissions, but of understanding how various factors interact at a global level.
“We note that the Earth has never in its history had a quasi-stable state that is around 2C warmer than the preindustrial and suggest that there is substantial risk that the system, itself, will ‘want’ to continue warming because of all of these other processes – even if we stop emissions,” she said. “This implies not only reducing emissions but much more."
