The EU is being sued for failing to set ambitious climate targets in sectors that contribute more than half of the bloc’s total greenhouse gas emissions.

Under current emission trajectories, temporarily overshooting the Paris global warming limit of 1.5 °C is a distinct possibility. Permanently exceeding this limit would substantially increase the probability of triggering climate tipping elements. Here, we investigate the tipping risks associated with several policy-relevant future emission scenarios, using a stylised Earth system model of four interconnected climate tipping elements.

Dr Sarah Benn has long been concerned about the climate crisis, diligently recycling until she was “blue in the face”. But the rise of the climate activist group Extinction Rebellion in 2019 inspired her and her husband to go further. “We thought: well, if we don’t do it then who else is going to?”

Le débat sur les nouveaux OGM est biaisé par les lobbies qui défendent toute une série d’intérêts économiques. A la faveur de sa présidence européenne, la Belgique doit se positionner dans ce dossier en facilitant l’élaboration d’une politique européenne qui donne la priorité à l’équité, à l’autonomie des agriculteur.e.s, à la santé publique et à l’environnement.

Anthropogenic emissions drive global-scale warming yet the temperature increase relative to pre-industrial levels is uncertain. Using 300 years of ocean mixed-layer temperature records preserved in sclerosponge carbonate skeletons, we demonstrate that industrial-era warming began in the mid-1860s, more than 80 years earlier than instrumental sea surface temperature records. The Sr/Ca palaeothermometer was calibrated against ‘modern’ (post-1963) highly correlated (R2 = 0.91) instrumental records of global sea surface temperatures, with the pre-industrial defined by nearly constant (<±0.1 °C) temperatures from 1700 to the early 1860s. Increasing ocean and land-air temperatures overlap until the late twentieth century, when the land began warming at nearly twice the rate of the surface oceans. Hotter land temperatures, together with the earlier onset of industrial-era warming, indicate that global warming was already 1.7 ± 0.1 °C above pre-industrial levels by 2020. Our result is 0.5 °C higher than IPCC estim

Permafrost and glaciers in the high Arctic form an impermeable ‘cryospheric cap’ that traps a large reservoir of subsurface methane, preventing it from reaching the atmosphere. Cryospheric vulnerability to climate warming is making releases of this methane possible. On Svalbard, where air temperatures are rising more than two times faster than the average for the Arctic, glaciers are retreating and leaving behind exposed forefields that enable rapid methane escape. Here we document how methane-rich groundwater springs have formed in recently revealed forefields of 78 land-terminating glaciers across central Svalbard, bringing deep-seated methane gas to the surface. Waters collected from these springs during February–May of 2021 and 2022 are supersaturated with methane up to 600,000 times greater than atmospheric equilibration. Spatial sampling reveals a geological dependency on the extent of methane supersaturation, with isotopic evidence of a thermogenic source. We estimate annual methane emissions from prog

Flash drought, characterized by unusually rapid drying, can have substantial impact on many socioeconomic sectors, particularly agriculture. However, potential changes to flash drought risk in a warming climate remain unknown. In this study, projected changes in flash drought frequency and cropland risk from flash drought are quantified using global climate model simulations. We find that flash drought occurrence is expected to increase globally among all scenarios, with the sharpest increases seen in scenarios with higher radiative forcing and greater fossil fuel usage. Flash drought risk over cropland is expected to increase globally, with the largest increases projected across North America (change in annual risk from 32% in 2015 to 49% in 2100) and Europe (32% to 53%) in the most extreme emissions scenario. Following low-end and medium scenarios compared to high-end scenarios indicates a notable reduction in annual flash drought risk over cropland. Flash droughts are projected to become more frequent unde

Overall, however, the climate crisis is bleaker than it has ever been. In October, a slew of reports laid bare how close the planet had neared to irreversible climate breakdown, with one UN study stating there was “no credible pathway in place to 1.5C”, the internationally agreed limit for global heating, and that progress on cutting carbon emissions was “woefully inadequate”.

A large majority of the UK public supports nonviolent direct action to protect the environment, according to an opinion poll. People also strongly backed solar power on farmland and opposed fracking. The poll indicates the unpopularity of a recent swathe of government policies, with more than twice as many people saying they trusted Labour to protect the environment as said they trusted the Conservatives.

Campaigners say protesters arrested for blocking roads getting ‘lost in prison system’ while on remand.

Human activity is putting the Earth on a trajectory towards environmental collapse. The SDGs were adopted in2015 to reconcile human activity with planetary boundaries. So far, the SDGs have not lived up to their promise in European Union member states. Most EU countries have seen socioeconomic development alongside environmental degradation. Progress towards environmental sustainability only occurs in countries with slow or negative socioeconomic trends.
