Climate
2025
Global temperature for 2025 should decline little, if at all, from the record 2024 level. Absence of a large temperature decline after the huge El Nino-spurred temperature increase in 2023-24 will provide further confirmation that IPCC’s best estimates for climate sensitivity and aerosol climate forcing were both underestimates. Specifically, 2025 global temperature should remain near or above +1.5C relative to 1880-1920, and, if the tropics remain ENSO-neutral, there is good chance that 2025 may even exceed the 2024 record high global temperature.
Tipping elements within the Earth system are increasingly well understood. Scientists have identified more than 25 parts of the Earth’s climate system that are likely to have “tipping points” – thresholds where a small additional change in global warming will cause them to irreversibly shift into a new state. The “tipping” of these systems – which include the Atlantic Meridional Overturning Circulation (AMOC), the Amazon rainforest and the Greenland ice sheet – would have profound consequences for both the biosphere and people. More recent research suggests that triggering one tipping element could cause subsequent changes in other tipping elements, potentially leading to a “tipping cascade”. For example, a collapsed AMOC could lead to dieback of the Amazon rainforest and hasten the melt of the Greenland ice sheet.
Eat-Lancet report recommended shift to more plant-based, climate-friendly diet but was extensively attacked online [...] The report recommended that if global red meat eating was cut by 50%, the “planetary health diet” would provide nutritious food to all while tackling the harms caused by animal agriculture, which accounts for over 14% of all greenhouse gas emissions worldwide. It suggested individuals – particularly in wealthy countries – should increase their consumption of nuts, pulses and other plant-based foods while cutting meat and sugar from their diets.
During the Cold War, the US poured support into Arctic military outposts and climate research amid fears of a Russian invasion. Climate change is still on the military’s radar as a threat multiplier.
As if there was any doubt, we can go ahead and officially add climate change to the list of things that we can’t count on billionaires to figure out for us. According to the New York Times, Breakthrough Energy, a joint venture between Bill Gates and a handful of other billionaires who at least nominally care about the environment, is laying off a significant portion of its staff, which will likely neuter its capability to lobby and influence policy.
The clear signs of human-induced climate change reached new heights in 2024, which was likely the first calendar year to be more than 1.5°C above the pre-industrial era, with a global mean near-surface temperature of 1.55 ± 0.13 °C above the 1850-1900 average.
Anuna De Wever werd bekend als initiatiefneemster van de scholierenactie “Spijbelen voor het klimaat” en de jongerenklimaatmarsen in 2019 en als woordvoerster van “Youth for Climate”. Daarmee volgde ze samen met Kyra Gantois en de Waalse Adelaïde Charlier het voorbeeld van de internationale bewegingen “School Strikes 4 Climate” en “Fridays for Future”, in gang gezet door de Zweedse activiste Greta Thunberg.

Donald Trump’s administration is to reconsider the official finding that greenhouse gases are harmful to public health, a move that threatens to rip apart the foundation of the US’s climate laws, amid a stunning barrage of actions to weaken or repeal a host of pollution limits upon power plants, cars and waterways.
The Trump administration is targeting climate organizations that received a Biden-era grant.
The U.S. military is canceling more than 90 studies, including some that U.S. Defense Secretary Pete Hegseth dismissed as climate change "crap." Military and intelligence officials have over the past decade identified potential security threats from climate change that include natural disasters in densely populated coastal areas and damage to American military bases worldwide.
Adam Greenfield author of Lifehouse, Taking Care of Ourselves in a World on Fire. A Lifehouse is an institution at the heart of each neighborhood that responds to the terrifying reality of climate collapse in our own communities.In this book Adam Greenfield, recovers lessons from the Black Panther survival programs, the astonishingly effective Occupy Sandy disaster-relief effort and the solidarity networks of crisis-era Greece, as well as municipalist Spain and autonomous Rojava, to show how practices of mutual care and local power can help shelter us from a future that often feels like it has no place for us...
Tougher laws said to be inspiring clandestine attacks on the ‘property and machinery’ of the fossil fuel economy
Climate change will fuel contests—and maybe wars—for land and resources.
The Atlantic Meridional Overturning Circulation (AMOC), vital for northwards heat transport in the Atlantic Ocean, is projected to weaken owing to global warming1, with significant global climate impacts2. However, the extent of AMOC weakening is uncertain with wide variation a …
US government stripping funds from domestic and overseas research amid warnings for health and public safety
One of the world’s most climate-ambitious governments is about to fall, replaced by a likely chancellor who says green policy went too far.
... An “acid” test of our interpretation will be provided by the 2025 global temperature: unlike the 1997-98 and 2015-16 El Ninos, which were followed by global cooling of more than 0.3°C and 0.2°C, respectively, we expect global temperature in 2025 to remain near or above the 1.5°C level. Indeed, the 2025 might even set a new record despite the present weak La Nina. There are two independent reasons. First, the “new” climate forcing due to reduction of sulfate aerosols over the ocean remains in place, and, second, high climate sensitivity (~4.5°C for doubled CO2) implies that the warming from recently added forcings is still growing significantly.
Reintroducing wolves to the Scottish Highlands could lead to an expansion of native woodland which could take in and store one million tonnes of CO2 annually, according to a new study.
January 2025 was the 18th month in a 19-month period with a global-average surface air temperature exceeding 1.5ºC above pre-industrial levels. According to the Copernicus Climate Change Service…
