Oil cartel warns ‘pressure may reach a tipping point’ and that ‘politically motivated campaigns put our prosperity’ at risk

Exclusive: UAE’s Sultan Al Jaber says phase-out of coal, oil and gas would take world ‘back into caves’

World Meteorological Organization says 2023 will be hottest year on record, leaving ‘trail of devastation and despair’

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.

The renowned US scientist’s new book examines 4bn years of climate history to conclude we are in a ‘fragile moment’ but there is still time to act

First complete ‘scientific health check’ shows most global systems beyond stable range in which modern civilisation emerged

Extreme weather is ‘smacking us in the face’ with worse to come, but a ‘tiny window’ of hope remains, say leading climate scientists

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

A collapse would bring catastrophic climate impacts but scientists disagree over the new analysis

Le pic de plutonium dans les sédiments des lacs canadiens marque l’aube d’une nouvelle ère où l’humanité domine la planète. Les scientifiques ont choisi le site qui représentera le début de l’ère de l’Anthropocène sur Terre. Il marquera la fin de 11 700 ans d’un environnement planétaire stable dans lequel l’ensemble de la civilisation humaine s’est développée et le début d’une nouvelle ère, dominée par les activités humaines. Le site est un lac d’effondrement situé au Canada. Il abrite des sédiments annuels présentant des pics clairs dus à l’impact colossal de l’humanité sur la planète à partir de 1950, du plutonium provenant des essais de la bombe à hydrogène aux particules issues de la combustion des combustibles fossiles qui ont arrosé le globe.

Plutonium spike in Canadian lake sediments marks dawn of new epoch in which humanity dominates planet

World Bank says subsidies costing as much as $23m a minute must be repurposed to fight climate crisis...

Ice-free summers inevitable even with sharp emissions cuts and likely to result in more extreme heatwaves and floods

World is on track for 2.7C and ‘phenomenal’ human suffering, scientists warn. Up to 1 billion people could choose to migrate to cooler places, the scientists said, although those areas remaining within the climate niche would still experience more frequent heatwaves and droughts. However, urgent action to lower carbon emissions and keep global temperature rise to 1.5C would cut the number of people pushed outside the climate niche by 80%, to 400 million.

Pools and well-watered gardens at least as damaging as climate emergency or population growth

Those with higher levels of PFAS in their blood had 40% lower chance of conceiving within a year of trying

Since 1992, the IPCC has highlighted rising greenhouse gases, marking their ‘widespread and unprecedented’ impacts by 2014

An unprecedented rise in plastic pollution has been uncovered by scientists, who have calculated that more than 170tn plastic particles are afloat in the oceans. They have called for a reduction in the production of plastics, warning that “cleanup is futile” if they continue to be pumped into the environment at the current rate.

Vast releases of gas, along with future ‘methane bombs’, represent huge threat – but curbing emissions would rapidly reduce global heating

Popularity of sport utility vehicles driving higher oil demand and climate crisis, say experts

The steady destruction of wildlife can suddenly tip over into total ecosystem collapse, scientists studying the greatest mass extinction in Earth’s history have found. Many scientists think the huge current losses of biodiversity are the start of a new mass extinction. But the new research shows total ecosystem collapse is “inevitable”, if the losses are not reversed, the scientists said.

The world is at risk of descending into a climate “doom loop”, a thinktank report has warned. It said simply coping with the escalating impacts of the climate crisis could draw resources and focus away from the efforts to slash carbon emissions, making the situation even worse.

An increase in the pace at which sea levels are rising threatens “a mass exodus of entire populations on a biblical scale”, the UN secretary general has warned. The climate crisis is causing sea levels to rise faster than for 3,000 years, bringing a “torrent of trouble” to almost a billion people, from London to Los Angeles and Bangkok to Buenos Aires, António Guterres said on Tuesday. Some nations could cease to exist, drowned under the waves, he said.

Claimants ClientEarth say the oil company’s plan puts the company at financial risk as the world transitions to clean energy, The directors of oil major Shell are being personally sued over their climate strategy, which the claimants say is inadequate to meet climate targets and puts the company at risk as the world switches to clean energy.

Three “super-tipping points” for climate action could trigger a cascade of decarbonisation across the global economy, according to a report. Relatively small policy interventions on electric cars, plant-based alternatives to meat and green fertilisers would lead to unstoppable growth in those sectors, the experts said. But the boost this would give to battery and hydrogen production would mean crucial knock-on benefits for other sectors including energy storage and aviation.

Humanity is now a ‘geological superpower’ and declaring a new epoch is critical to tackling its impact, scientists say
