The UK has announced much harsher rules for asylum seekers including the prospect of more deportations for those whose applications fail. The US is trebling the size of its deportation force. The EU is doubling its border budgets. And in the coming decades, hundreds of millions of people might be displaced by ecological changes.

Rain-fed agriculture, the backbone of rural livelihoods, are no longer predictable as droughts follows floods.
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.

Exclusive: ‘Devastating consequences’ now inevitable but emissions cuts still vital, says António Guterres in sole interview before Cop30
Named one of the “world’s ten most influential intellectuals” by MIT, Douglas Rushkoff is an author and documentarian who studies human autonomy in a digital age. Rushkoff’s work explores how different technological environments change our relationship to narrative, money, power, and one another. He coined such concepts as “viral media,” “screenagers,” and “social currency,” and has been a leading voice for applying digital media toward social and economic justice. In the conversation we talk about the power of ideas, our disconnection from reality, going meta, ancestral fears, tech billionaires mindset and how they are preparing for the apocalypse. We also reflect on the urgent need to be more human and reconnect with what is essential.
We are an international group of researchers and practitioners interested in the emerging fields of post-growth and ecological macroeconomics. Our aim is to advance economic theory, methodology and policy in order to adequately address some of the biggest challenges of our time: climate change, rising inequality, and financial instability.
Author Adam Greenfield demonstrates the power of mutual aid and community networks, but they lack to power to fundamentally change societyIn his book Lifehouse, Adam Greenfield shows that ordinary people are capable of organising themselves and running their own lives even in the most difficult circumstances.
Four key parts of the Earth’s climate system are destabilising, according to a new study with contributions from the Potsdam Institute for Climate Impact Research (PIK). Researchers analysed the interconnections of four major tipping elements: the Greenland ice sheet, the Atlantic meridional overturning circulation (AMOC), the Amazon rainforest and the South American monsoon system. All four show signs of diminished resilience, raising the risk of abrupt and potentially irreversible changes.

Conservative leader Kemi Badenoch has described her plan to “maximise extraction” of the UK’s oil and gas from the North Sea as a “common sense” energy policy. Politicians are using language like this increasingly often – calling themselves “pragmatic” on climate change and invoking “common sense”. It sounds reasonable, reassuring, and grownup – the opposite of “hysterical” campaigners or “unrealistic” targets.
The vast ice of Antarctica has long seemed impregnable. But sudden changes are arriving – from shrinking sea ice to melting ice sheets and slowing ocean currents.
Predictably, soon, most young people will reject extremist views. This will be none too soon because it is the essential step leading to global political leadership that appreciates the threat posed by climate’s delayed response to human-made changes of Earth’s atmosphere. Then the annual fraud of goals for future “net zero” emissions announced at United Nations COP (Conference of Parties) meetings might be replaced by realistic climate policies. It is important, by that time, that we have better knowledge of the degree and rate at which human-made forcing of the climate system must be decreased to avoid irreversible, unacceptable consequences.
Our modelling of European fish species shows a patchwork of winners and losers as sea temperatures rise.
– how climate scientists and the IPCC still won’t tell the truth about accelerating climate change.

The Atlantic meridional overturning circulation (AMOC) is an important tipping element in the climate system. There is a large uncertainty whether the AMOC will start to collapse during the century under future climate change, as this requires long climate model simulations which are not always available. Here, we analyze targeted climate model simulations done with the Community Earth System Model (CESM) with the aim to develop a physics-based indicator for the onset of an AMOC tipping event. This indicator is diagnosed from the surface buoyancy fluxes over the North Atlantic Ocean and is performing successfully under quasi-equilibrium freshwater forcing, freshwater pulse forcing, climate change scenarios, and for different climate models. An analysis consisting of 25 different climate models shows that the AMOC could begin to collapse by 2063 (from 2026 to 2095, to percentiles) under an intermediate emission scenario (SSP2-4.5), or by 2055 (from 2023 to 2076, to percentiles) under a high-end emission scenar
The planet is edging close to irreversible change, according to the most comprehensive probability analysis yet of climate “tipping points.”
This article examines the technocentric bias that characterizes climate mitigation literature, focusing on the reports of the IPCC's Working Group III. This bias stems from structural features of the scientific field that prioritizes innovation, leading to the overrepresentation of technological solutions in climate research. Funding mechanisms further reinforce this tendency by incentivizing collaboration with industrial R&D, creating a self-reinforcing loop in which scientific authority and industrial interests converge. The IPCC's institutional positioning—as a policy-relevant yet politically cautious body—amplifies this dynamic by favoring allegedly “cost-effective” technological pathways that lack practical feasibility.
As corporate interest in ocean carbon removal grows, researchers from Woods Hole Oceanographic Institution are testing the safety and effectiveness of one such technique in the Gulf of Maine.

The Trump administration is releasing its proposal to undo the “endangerment finding,” the long-standing rationale and legal imperative for regulating greenhouse gases under the Clean Air Act
The constant deluge of bad news about rising global temperatures and their impacts can make it feel like the world is ending. Is it?
Bad climate news is everywhere. Africa is being hit particularly hard by climate change and extreme weather, impacting lives and livelihoods. We are living in a world that is warming at the fastest rate since records began. Yet, governments have been slow to act.
