Should the world continue on its present pathway — making gestures toward moderate reductions in emissions but not meaningfully reducing global carbon levels (a scenario close to what the United Nations refers to as SSP2-4.5) — the planet will likely surpass the Paris Agreement’s goal of limiting average warming to 1.5 degrees Celsius and instead warm approximately 2.7 degrees. That pathway, which accounts for population growth in hot places, could lead to 2 billion people falling outside of the climate niche within just the next eight years, and 3.7 billion doing so by 2090. But the study’s authors, who have argued in other papers that the most extreme warming scenarios are well within the realm of possibility, warn that the worst cases should also be considered. With 3.6 degrees of warming and a pessimistic climate scenario that includes ongoing fossil fuel use, resistance to international migration and much more rapid population growth (a scenario referred to by the U.N. as SSP3-7), the shifting climate niche could pose what the authors call “an existential risk,” directly affecting half the projected total population, or, in this case, as many as 6.5 billion people.
The data suggests the world is fast approaching a tipping point, after which even small increases in average global temperature will begin to have dramatic effects. The world has already warmed by about 1.2 degree Celsius, pushing 9% of the earth’s population out of the climate niche. At 1.3 degrees, the study estimates that the pace would pick up considerably, and for every tenth of a degree of additional warming, according to Lenton, 140 million more people will be pushed outside of the niche. “There’s a real nonlinearity lurking in there that we hadn’t seen before,” he said.
Quindi il prossimo idiota che trovate per strada o dice in TV che sono tutte esagerazioni e che a lui piacciono le brum-brum a scoppietti... siete autorizzati a prenderlo a schiaffi, perché con il suo atteggiamento e la sua ignoranza sta mettendo in pericolo la vostra vita.
