Published in March, the IPPCâs AR6 Synthesis Report on Climate Change updates its predictions of the effects of temperature rises. It starkly concludes that those temperature rises will have a bigger impact at lower temperatures than previously predicted. Charlotte Edmond, writing for the World Economic Forum, picks out five charts from the report to illustrate the point: the range of likely temperature rises; global map of change in temperature, … [Read more...]
New AI model predicts 1.5C temperature rise is likely in 2030s even if emissions decline
A new artificial intelligence model is predicting that 2C warming is likely to occur and sooner than expected, even if current low-emissions strategies are successful, explains Josie Garthwaite at Stanford University. The Stanford-developed AI uses âneural networkâ learning from vast quantities of past data, predicting that the 1.5C threshold is likely to be crossed in the next 10 to 15 years. Thatâs regardless of how much greenhouse gas … [Read more...]
Interpreting the Paris Agreement: the 1.5C and 2C targets are not two different options
Carl-Friedrich Schleussner and Gaurav Ganti at Humboldt University of Berlin, writing for Carbon Brief, want to clear up confusion over the 1.5C and 2C pathways. Their concern is that some people are interpreting the Paris Agreementâs wording as two separate targets, one simply better than the other. But they should not be seen as two different options. The objective of âwell below 2Câ must be seen by modellers and policy-makers as a clear … [Read more...]
Paris Agreement âGlobal Stocktakeâ should focus on individual nations too
Itâs time for national governments to focus on the short-term domestic actions needed to meet their 1.5°C goals, argue Anna PĂ©rez CatalĂ , Henri Waisman, Marta Torres Gunfaus and Ariadna Anisimov at IDDRI. Analyses of emissions gaps at a collective and global level wonât be enough, the current purpose of the Global Stocktake (GST) of the Paris Agreement. The first GST runs from 2021 to 2023 and the process will be repeated every 5 years. The … [Read more...]
