By Yangyang Xu, Veerabhadran Ramanathan and David G. Victor in Nature: “the latest IPCC special report underplays another alarming fact: global warming is accelerating [italics mine] Three trends — rising emissions, declining air pollution and natural climate cycles — will combine over the next 20 years to make climate change faster and more furious than anticipated. In our view, there’s a good chance that we could breach the 1.5 °C level by 2030, not by 2040 as projected in the special report (see ‘Accelerated warming’). The climate-modelling community has not grappled enough with the rapid changes that policymakers care most about, preferring to focus on longer-term trends and equilibria.”
