Average global temperature in November was 1.62C above preindustrial levels, bringing average for the year to 1.60C. Data for November from the EU’s Copernicus Climate Change Service (C3S) found the average global surface temperature for the month was 1.62C above the level before the mass burning of fossil fuels drove up global heating. With data for 11 months of 2024 now available, scientists said the average for the year is expected to be 1.60C, exceeding the record set in 2023 of 1.48C.

De jeunes militants pour le climat parlent de l’état de la politique dans le monde. Cette année, des élections ont lieu dans le monde entier, couvrant près de la moitié de la population mondiale. Il est également probable que cette année soit, une fois de plus, la plus chaude jamais enregistrée, alors que la crise climatique s’intensifie. Le Guardian a demandé à de jeunes militants pour le climat du monde entier ce qu’ils attendaient des élections et si la politique est efficace dans la lutte contre le réchauffement climatique.

This year elections are taking place across the globe, covering almost half of the world’s population. It is also likely to be, yet again, the hottest year recorded as the climate crisis intensifies. The Guardian asked young climate activists around the world what they want from the elections and whether politics is working in the fight to halt global heating.

Total is 20% higher than thought and may have implications for collapse of globally important north Atlantic ocean currents The Greenland ice cap is losing an average of 30m tonnes of ice an hour due to the climate crisis, a study has revealed, which is 20% more than was previously thought. Some scientists are concerned that this additional source of freshwater pouring into the north Atlantic might mean a collapse of the ocean currents called the Atlantic meridional overturning circulation (Amoc) is closer to being triggered, with severe consequences for humanity.

Saudi Arabia is driving a huge global investment plan to create demand for its oil and gas in developing countries, an undercover investigation has revealed. Critics said the plan was designed to get countries “hooked on its harmful products”. Little was known about the oil demand sustainability programme (ODSP) but the investigation obtained detailed information on plans to drive up the use of fossil fuel-powered cars, buses and planes in Africa and elsewhere, as rich countries increasingly switch to clean energy.

World Meteorological Organization sees ‘no end in sight to the rising trend’, largely driven by fossil fuel burning

Michael Mann, de l’université de Pennsylvanie aux États-Unis, fait partie des climatologues les plus en vue depuis qu’il a publié, en 1999, le célèbre graphique en forme de crosse de hockey, qui montre comment les températures mondiales ont grimpé en flèche au cours du siècle dernier. Pour comprendre la situation difficile dans laquelle nous nous trouvons aujourd’hui, Michael Mann a remonté l’histoire du climat de la Terre afin d’avoir une vision plus claire de notre avenir potentiel. « Nous disposons d’une période de 4 milliards d’années dont nous pouvons tirer des enseignements », a-t-il déclaré dans une interview au Guardian.
