Intempéries

Climate scientists have told the Guardian they expect catastrophic levels of global heating. Here’s what that would mean for the planet

Europe is no exception when it comes to the consequences of climate change. It is the fastest warming continent, with temperatures rising at around twice the global average rate.

Heatwaves, wildfires and floods are just the ‘tip of the iceberg’, leading climate scientists say

Antarctica’s sea ice levels are plummeting as extreme weather events happen faster than scientists predicted

After hottest day ever, researchers say global heating may mean future of crop failures on land and ‘silent dying’ in the oceans

It’s not that our models can’t simulate small-scale weather – they’re basically the same models we use for weather forecasting – it’s just very computationally expensive to have them zoom in and run in “weather mode” to get a highly detailed simulation.

Abstract. The summer of 2022 was memorable and record-breaking, ranking as the second hottest summer in France since 1900, with a seasonal surface air temperature average of 22.7 ∘C. In particular, France experienced multiple record-breaking heatwaves during the meteorological summer. As the main heat reservoir of the Earth system, the oceans are at the forefront of events of this magnitude which enhance oceanic disturbances such as marine heatwaves (MHWs). In this study, we investigate the sea surface temperature (SST) of French maritime basins using remotely sensed measurements to track the response of surface waters to the atmospheric heatwaves and determine the intensity of such feedback. Beyond the direct relationship between SSTs and surface air temperatures, we explore the leading atmospheric parameters affecting the upper-layer ocean heat budget. Despite some gaps in data availability, the SSTs measured during the meteorological summer of 2022 were record-breaking, the mean SST was between 1.3 and 2.6

Chief meteorologist says extreme temperatures ‘entirely consistent’ with human-induced climate crisis

In March, the north and south poles had record temperatures. In May in Delhi, it hit 49C. Last week in Madrid, 40C. Experts say the worst effects of the climate emergency cannot be avoided if emissions continue to rise

the new study has uncovered five other events around the world which were even more severe but were never reported. “The recent heatwave in Canada and the United States shocked the world. Yet we show there have been some even greater extremes in the last few decades. Using climate models, we also find extreme heat events are likely to increase in magnitude over the coming century – at the same rate as the local average temperature,”
