Sultan Ahmed Al Jaber, the president of the COP28 climate summit due to be held in the United Arab Emirates (UAE) in December, has said “the phasedown of fossil fuels is inevitable”, Reuters reports. Carbon Brief has also published a detailed guest post from the authors of this study, too. While more than 90% of the global economy is covered by net-zero plans, the only countries seen as having “high confidence” of meeting them are developed ones, including the UK, the EU and New Zealand, the article continues.
Relatedly, another new study, released to coincide with the Bonn climate talks, finds that around 90% of nations’ net-zero plans are unlikely to be achieved, which could result in Earth warming by 2.4C, reports the Times. The analysis, which has been published to coincide with UN climate negotiations in Bonn, Germany this week is a “timely wake-up call”, notes the Irish Times. Carbon Brief published a detailed guest post from two of the study’s authors yesterday. From 2013 to 2022, average annual emissions hit an all-time high of 54bn tonnes of CO2 or equivalent – about 1,700 tonnes every second – leading to an unprecedented rate of more than 0.2C of human-induced warming per decade, reports NDTV. However, due to three further years of high emissions and new scientific understanding on how particles of air pollution affect the climate, this has been halved, reports the Washington Post. The UN Intergovernmental Panel on Climate Change (IPCC) estimated that, from early 2020, only 500bn more tonnes of CO2 could be burnt to keep warming within 1.5C.
Only 250bn tonnes of CO2 can now be emitted to avoid the accumulation that would raise temperatures by 1.5C, according to a new study, it continues.
Greenhouse gas emissions have reached an all-time high, as the world rapidly runs out of “carbon budget” threatening “unprecedented” levels of global heating, reports the Guardian.
