There’s a 50:50 chance the planet will pass the 1.5C warming threshold in the next 5 years – CNN

The report says that surpassing the limit is likely to be temporary — temperatures could come back down again — but science shows that even a temporary overshoot could bring “This study shows — with a high level of scientific skill — that we are getting measurably closer to temporarily reaching the lower target of the The plummeting water levels at the lake are the result of a climate-change fueled megadrought in the American West. A study published by Nature Climate Change found the period from 2000 to 2021 was the driest in 1,200 years in the area.”For as long as we continue to emit greenhouse gases, temperatures will continue to rise,” Taalas said. “And alongside that, our oceans will continue to become warmer and more acidic, sea ice and glaciers will continue to melt, sea level will continue to rise and our weather will become more extreme. Arctic warming is disproportionately high and what happens in the Arctic affects all of us.”Ice sheet and glacier melt in the Arctic will lead to accelerated sea level rise, which could be both irreversible for centuries and disastrous for the planet as the risks of extreme flooding increase.The report highlights how fast humans are warming the planet, said Andrew King, a lecturer in Climate Science at the University of Melbourne.”Our greenhouse gas emissions are still at near-record highs and until we get emissions down to net-zero, we’re going to continue to see global warming,” he said. Net zero refers to a state where the world reduces its greenhouse gas emissions as much as possible, and offsets any that are hard to avoid, whether through the use of technology or tree-planting to capture carbon dioxide from the atmosphere. King added: “If we fail to take that action we will have much worse heatwaves and bushfire conditions as well as coral reefs that have been decimated beyond recognition.” …
