Exclusive: As wildfires rage, Frank Elderson says more work needed to assess risk from collapse of ecosystem services
Herders and experts tell the BBC how Africa's camels are suffering because of extreme heat.
Imagine being told that your children cannot play outside because the grass and soil in your local area is so polluted that it endangers their health. You are not allowed to eat the eggs from the chickens in your garden because eating them could diminish your immune system and/or lead to certain types of cancer. No, this is not the plot of a dystopian novel these are very real consequences for people living in places that are severely polluted by PFAS. Also known as forever chemicals.
For most of the modern era, capitalism justified itself through growth. Industrial societies converted vast amounts of fossil energy into production, wealth, and rising living standards. Roads, bridges, power grids, schools, and public institutions expanded alongside the economy. Inequality and exploitation remained deeply embedded in the system, but they were partly obscured by a broader story of material progress.
Nearly every indicator of climate change is flashing red. But we still hold the tools available to bring the planet back into balance
Cet article rapporte la difficulté du secteur manufacturier en Grande Bretagne à faire face à l’augmentation du cout de l'énergie. Dans l'ombre de cet article apparait ce qui sera la réalité à un moment donné, sans pétrole bon marché, l'industrie manufacturière ne peut pas fonctionner dans les conditions actuelles. Le contrat social sera rompu et il faudra réinventer une manière de vivre ensemble. La situation en Grande Bretagne est peut-être exacerbée par le Brexit et la situation insulaire mais elle est l'avant-poste de ce qui attend une bonne part du monde industrialisé, à moins de relancer le charbon avec toutes les conséquences sur le dérèglement climatique et la santé des personnes que nous connaissons.
The process of relocating people from New Orleans should start immediately, as the city has reached a “point of no return” that will see it surrounded by the ocean within decades due to the climate crisis, a stark new study has concluded. Ongoing sea-level rise and the rampant erosion of wetlands in southern Louisiana will swallow up the New Orleans area within a few generations, with the new paper estimating the city “may well be surrounded by the Gulf of Mexico before the end of this century”.
Climate models show considerable discrepancies in their future projections around the Atlantic, mainly due to uncertainties in the fate of the Atlantic Meridional Overturning Circulation (AMOC). Climate models suggest a reduction in AMOC strength of 32 ± 37% by 2100 (90% probability, Shared Socioeconomic Pathways 2-4.5 scenario, Coupled Model Intercomparison Project Phase 6). To refine this estimate and reduce its uncertainty, we use four different observational constraint methods. The best one, which provides the lowest leave-one-out error, integrates a large set of observable variables using ridge-regularized linear regression—a method unusual in climate science. It gives an estimate of the AMOC slowdown of 51 ± 8% (90% probability), i.e., a weakening ∼ 60% stronger than suggested by the multimodel mean. This refinement mainly results from correcting a bias in South Atlantic surface salinity, consistent with recent studies emphasizing its role in the proximity to an AMOC tipping point. This more substantial
Wildfires used to die down and even stop at night with cooler temperatures and increased humidity. But a study released Friday says climate change is making burning weather more around the clock in North America because night is becoming warmer and drier. Canadian fire scientists say potential burning hours for fires have increased 36% in the last 50 years. California now has about 550 more fire-friendly hours a year than it did in the 1970s. North American summer nights are warming faster than days, evening relief is evaporating for forests and that means the area of land burned is soaring.
Most research on “forever chemicals” focuses on how best to remove them from the environment. But solutions to tricky problems often emerge from the most unexpected of places—as demonstrated by a new study that instead redirects the pollutants into becoming tools for extracting precious lithium. In a recent Nature Water study, a team led by Rice University researchers describes a novel way to use spent perfluoroalkyl and polyfluoroalkyl substances, or PFAS, to recover lithium from high-salinity brine pools. The team tapped into the fluorine content inside PFAS leftovers, using it to attract lithium from briny water. Remarkably, the team was able to collect lithium fluoride at 99% purity and confirmed that the sample was pure enough to boost the stability and performance of lithium-ion batteries.
Seven Ukrainians arrested and money-laundering investigation launched in latest spat between Kyiv and Budapest
What is currently happening in Brussels under the guise of regulatory simplification is being presented as something technical and logical. Less regulatory pressure, more competitiveness. A series of so-called omnibus bills are intended to streamline legislation. Reporting obligations are being limited and reassessments of raw materials postponed. It sounds like administrative efficiency. In Washington, things are moving even faster: Trump is dismantling the basis for climate laws while the world continues to warm up. The framing is the same: rules slow down businesses, and a slowed-down business community makes us poor. But that reasoning assumes something that is not true: that everyone wants the same thing from the market.
The world seems headed into another El Nino, just 3 years after the last one. Such quick return normally would imply, at most, an El Nino of moderate strength, but we suggest that even a moderately strong El Nino may yield record global temperature already in 2026 and still greater temperature in 2027. The extreme warming will be a result mainly of high climate sensitivity and a recent increase of the net global climate forcing, not the result of an exceptional El Nino, per se. We find that the principal drive for global warming acceleration began in about 2015, which implies that 2°C global warming is likely to be reached in the 2030s, not at midcentury.
New year, new acronym! The newly established Intergovernmental Science-Policy Panel on Chemicals, Waste and Pollution (ISP-CWP) will meet in its first Plenary session from February 2-6 in Geneva, Switzerland. The Panel is designed to provide scientific assessments on chemicals, waste, and pollution to inform policymakers at national, regional, and international levels.
Testimony from medics, morgue and graveyard staff reveals huge state effort to conceal systematic killing of protesters
The decline in the health of nature around the world poses a threat to the UK's security and prosperity, an intelligence committee has concluded in a long-awaited report. The document warns of "cascading risks" from the degradation of some of the planet's most important ecosystems, including conflict, migration and increased competition for resources.
Legal action has brought important decisions, from the scrapping of fossil fuel plants to revised climate plans
I always say that models are not predictions; they are qualitative illustrations of what the future could be. But as the future gets closer to the present, models can start being seen as predictive tools. It is the weather/climate dichotomy, so aptly exploited to confuse matters by politically minded people in the discussion about climate. Right now, we are getting close to the point that we could forecast a collapse in the same way as we can forecast the trajectory of a tropical storm. So, you remember how “The Limits to Growth” generated a long term forecast in 1972. Here it is
A deal is welcome after talks nearly collapsed but the final agreement contains small steps rather than leaps
22 of the planet’s 34 vital signs are at record levels, with many of them continuing to trend sharply in the wrong direction. This is the message of the sixth issue of the annual “State of the climate” report. The report was prepared by an international coalition with contribution from the Potsdam Institute for Climate Impact Research (PIK) and led by Oregon State University scientists. Published today in BioScience, it cites global data from the Intergovernmental Panel on Climate Change (IPCC) in proposing “high-impact” strategies.
