Acknowledging that progress had been too slow, leaders agreed to “revisit and strengthen” their national climate targets if possible over the coming year — rather than waiting every five years, as envisioned under the 2015 Paris climate accord.Global greenhouse gas emissions The push came as part of the effort to hold average global warming to no more than 1.5 degrees Celsius, or 2.7 degrees Fahrenheit, compared with preindustrial levels — a key threshold past which scientists have said disastrous impacts become far more likely.“Few governments have really done anything to substantially move the dial.” According to the independent Climate Action Tracker, as of Thursday only 21 countries have submitted updated national climate commitments as leaders are set to gather at the summit, which starts Nov. 6 in Egypt — and not even all those newer plans contain more ambitious goals.In an annual report published last week, the organization found that despite lofty vows from world leaders, existing climate pledges put the Earth on track to warm by a troubling 2.4 degrees Celsius (4.3 degrees Fahrenheit) by the end of the century.“We must close the emissions gap before climate catastrophe closes in on us all.” Given all that is at stake, and all the suffering that scientists say lies ahead without rapid and far-reaching changes, it seems logical that governments around the planet would act with more urgency and cooperation despite the competing demands of other crises, Höhne said."
