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”.
There is reason to expect that global temperatures will continue to increase over the remainder of the year, as a strong El Niño event is expected

Even if global warming does not exceed two degrees, it could lead to more serious consequences than expected. This is the conclusion of a new study published in Nature.
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.

Thousands of rallies are expected across the U.S. on Saturday as part of the latest “No Kings” protest against the policies of President Donald Trump and his administration. Organizers said more than 3,200 events are planned in all 50 states for what they hope could be the largest single-day nonviolent protest in U.S. history. The two previous No Kings events attracted millions of participants.
Climate change is causing measurable harm globally1,2. Political and legal efforts seek to link these damages with specific emissions, including in discussions of loss and damage (L&D)3,4; however, no quantitative definition of L&D exists5,6, nor is there a framework to link past and future emissions from specific sources to monetized, location-specific damages. Here we develop such a framework, which is integrated with recent efforts to estimate the social cost of carbon7. Using empirical estimates of the non-linear relationship between temperature and aggregate economic output, we show that future damages from past emissions—one component of L&D—are at least an order of magnitude larger than historical damages from the same emissions. For instance, one tonne of CO2 emitted in 1990 caused US$180 in discounted global damages by 2020 ($40–530) and will cause an additional $1,840 through 2100 ($500–5,700). Thus, settling debts for past damages will not settle debts for past emissions. In other illustrative esti

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.
The Gulf Stream is part of the Atlantic Meridional Overturning Circulation (AMOC). The AMOC is a tipping element and may collapse under changing forcing. However, the role of the Gulf Stream in such a tipping event is unknown. Here, we investigate the link between the AMOC and Gulf Stream using a high-resolution (0. 1°) stand-alone ocean simulation, in which the AMOC collapses under a slowly-increasing freshwater forcing. AMOC weakening gradually shifts the Gulf Stream near Cape Hatteras northward, followed by an abrupt northward displacement of 219 km within 2 years. This rapid shift occurs a few decades before the simulated AMOC collapse. Satellite altimetry shows a significant (1993–2024, p < 0.05) northward Gulf Stream trend near Cape Hatteras, which is also confirmed in subsurface temperature observations (1965–2024, p < 0.01). These findings provide indirect evidence for present-day AMOC weakening and demonstrate that abrupt Gulf Stream shifts can serve as early warning indicator for AMOC tipping.
 As climate protests are mounting across Italy, there is a corresponding escalation in repressive responses from public authorities. This trend is not unique to Italy but is rather widespread throughout Europe, as evidenced by frequent reports in national newspapers... What sets Italy apart from other European nations is the spectacular increase in the use of preventive measures by the public security administration.

Per- and polyfluoroalkyl substances (PFAS) have been at the center of numerous toxicological and environmental concerns and regulatory scan- dals for two decades. Previous research has shown a long history of active obfuscation, misdirection (‘science bending’) and regulatory manipulation by the largest halogenation businesses, related to the depletion of the ozone layer and the toxicity of some fluorinated surfactants (PFOS and PFOA). We screened publications for potential evidence of other strategies of deception and obfuscated information regarding PFAS and fluoropolymers. A directed effort was identified to influence the scientific understanding of the environmental source and effects of ultrashort PFAS, especially trifluoroacetic acid (TFA). Critical issues in the current analytical approach to PFAS monitoring were identified, as well as evidence of a silently abandoned “total organofluoride” technique. The non-specific character of the production, incineration and degradation processes is discussed, inc
In one of the most comprehensive empirical studies to date of AI strategic reasoning, Professor Kenneth Payne of King’s College London examined how large language models navigate simulated nuclear crises. Across 21 scenarios, the models displayed sophisticated escalation logic consistent with classical strategic theory – yet nuclear signalling occurred in 95% of games and no model ever chose outright concession. The findings challenge assumptions about AI restraint and offer new tools for defence analysis.

What if the real danger wasn’t the crises ahead… but the established illusion that we can solve them without changing the system that produces said crises? In this uncompromising and deeply eye-opening talk, renowned systems thinker and strategist Arthur Keller challenges one of the most comforting ideas of our time: the belief that “solutions exist” to the great planetary predicaments of our time. Climate action, energy transition, technical innovation… are all crucial, yet they’re somewhat off topic if they remain integrated within a system that inexorably turns nature into waste. Arthur reframes the situation with brutal clarity. Humanity is not facing an ecological crisis: it is nature that’s facing a human crisis. The problematic is no collection of isolated problems to tackle one by one: it is rather the symptom of a civilization operating beyond planetary limits. Decarbonizing energy without transforming the underlying system, he argues, is like treating cancer with painkillers. The disease keeps sprea
