The Tyndall Centre for Climate Change Research notes that there are no signs of a decrease in global CO2 emissions. Tyndall Centre: Global carbon emissions in 2022 remain at record levels – with no sign of the decrease that is urgently needed to limit warming to 1.5°C, according to the Global Carbon Project science team.…
Our environment involves many different systems, and some of them are close to changing in drastic ways, for human time scales irreversible. Exceeding 1.5°C global warming could trigger multiple climate tipping points Science (Study): Climate tipping points are conditions beyond which changes in a part of the climate system become self-perpetuating. These changes may lead…
VOX notes that Pakistan has more than 7,000 glaciers, and that changes in climatic conditions melting them, fueling floodwaters. A series of extreme floods has utterly devastated the South Asian nation, which is home to some 225 million people, washing away roads and buildings, destroying farms, and stranding hundreds of thousands. Over the weekend, which brought…
Ars Technica: New technique shows old temperatures were much hotter than thought. Results imply Earth may be more sensitive to carbon dioxide than previously known. In a paper recently published in Science, Professor Nele Meckler of the University of Bergen and colleagues argue that the climate between around 35 and 60 million years ago may have been…
New research on Antarctica, including the first map of iceberg calving, doubles the previous estimates of loss from ice shelves and details how the continent is changing. NASA: The greatest uncertainty in forecasting global sea level rise is how Antarctica’s ice loss will accelerate as the climate warms. Two studies published Aug. 10 and led…
NASA: The huge amount of water vapor hurled into the atmosphere, as detected by NASA’s Microwave Limb Sounder, could end up temporarily warming Earth’s surface. When the Hunga Tonga-Hunga Ha’apai volcano erupted on Jan. 15, it sent a tsunami racing around the world and set off a sonic boom that circled the globe twice. The…
Nature (February 2022): “Methane levels are growing dangerously fast,” says Euan Nisbet, an Earth scientist at Royal Holloway, University of London, in Egham, UK. The emissions, which seem to have accelerated in the past few years, are a major threat to the world’s goal of limiting global warming to 1.5–2 °C over pre-industrial temperatures, he…
(CNN)A tsunami has hit Tonga’s largest island, Tongatapu, and reportedly sent waves flooding into the capital after an underwater volcano in the South Pacific exploded in a violent eruption on Saturday, sending a cloud of ash and gas steam into the air.Satellite imagery shows a massive ash cloud and shockwaves spreading from the eruption. The…
Recent published research shows the danger of massive, potentially irreversible, global sea-level rise within the next couple of centuries should temperatures overshoot 2°C. Perhaps most sobering, this loss may become rapid and permanent, with no halt in ice loss even should CO2 concentrations return t pre-industrial levels; and rates approaching 5 cm/year by 2150, and…
