Record heat, massive fires, deadly floods... August has barely begun, but the summer of 2025 is already marked by a cascade of destructive and deadly weather in the Northern Hemisphere.

A subreddit tracking apocalyptic news in a calm, logical way comforts users who believe the end The threat of nuclear war, genocide in Gaza, ChatGPT reducing human cognitive ability, another summer of record heat. Every day brings a torrent of unimaginable horror. It used to be weeks between disasters, now we’re lucky to get hours.

These are difficult times indeed, with terrible news on many fronts. What are the prospects for the degrowth1 alternative as we move through 2025? Dark times: the current context First, we need to understand what is going on around us: what is the evolving context with which degrowth has to contend, and to which it has to present a viable alternative?

Recent simulations using the Community Earth System Model (CESM) indicate that a tipping event of the Atlantic Meridional Overturning Circulation (AMOC) would cause Europe to cool by several degrees. This AMOC tipping event was found under constant pre-industrial greenhouse gas forcing, while global warming likely limits this AMOC-induced cooling response. Here, we quantify the European temperature responses under different AMOC regimes and climate change scenarios. A strongly reduced AMOC state and intermediate global warming (C, Representative Concentration Pathway 4.5) has a profound cooling effect on Northwestern Europe with more intense cold extremes. The largest temperature responses are found during the winter months and these responses are strongly influenced by the North Atlantic sea-ice extent. Enhanced North Atlantic storm track activity under an AMOC collapse results in substantially larger day-to-day temperature fluctuations. We conclude that the (far) future European temperatures are dependent o

A new study uncovers Earth’s deep temperature history and shows just how tightly carbon dioxide has always controlled the climate

Critical minerals, which are essential for a range of energy technologies and for the broader economy, have become a major focus in global policy and trade discussions. Price volatility, supply chain bottlenecks and geopolitical concerns make the regular monitoring of their supply and demand extremely vital.

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.

We must learn from the past. We cannot remain silent in the face of authoritarian attacks on our peers, even if they have not yet come for us.

Last month was the hottest January on record, blitzing the previous high and stunning climate scientists who expected cooler La Niña conditions to finally start quelling a long-running heat streak. The Copernicus Climate Change Service said January was 1.75C hotter than pre-industrial times, extending a persistent run of historic highs over 2023 and 2024, as human-caused greenhouse gas emissions heat the planet.

The students behind the Stand Up for Science protests

Amid President Donald Trump’s attacks on government scientists and science funding, researchers are arranging rallies to “Stand Up for Science” in Washington, D.C., and nationwide on March 7

The March for Science (formerly known as the Scientists' March on Washington)[6] was an international series of rallies and marches held on Earth Day. The inaugural march was held on April 22, 2017, in Washington, D.C., and more than 600 other cities across the world.[7][8][9][10][11] According to organizers, the march was a non-partisan movement to celebrate science and the role it plays in everyday lives.[12] The goals of the marches and rallies were to emphasize that science upholds the common good and to call for evidence-based policy in the public's best interest.[11][13] The March for Science organizers, estimated global attendance at 1.07 million, with 100,000 participants estimated for the main March in Washington, D.C., 70,000 in Boston, 60,000 in Chicago, 50,000 in Los Angeles, 50,000 in San Francisco,[14] 20,000 in Seattle, 14,000 in Phoenix, and 11,000 in Berlin.[15]

The tiny former Soviet republic’s determination not to be cowed by the Kremlin could provide a template for the west on how to hold back the tide of subversion and corruption

... 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.

The 20th edition of the Global Risks Report 2025 reveals an increasingly fractured global landscape, where escalating geopolitical, environmental, societal and technological challenges threaten stability and progress. This edition presents the findings of the Global Risks Perception Survey 2024-2025 (GRPS), which captures insights from over 900 experts worldwide. The report analyses global risks through three timeframes to support decision- makers in balancing current crises and longer-term priorities.

A collapse would bring catastrophic climate impacts but scientists disagree over the new analysis

The report’s conclusion that staying below 2°C this century will only happen if emissions reach net zero by 2050 is well publicised. But there is one, rather more urgent addendum to that: global emissions must peak some time in the middle of this decade. In other words, within the next few years.

A new report has found that by 2025, the world must remove 1 Gigatonne, or 1 billion tonnes, of carbon from the atmosphere to keep global warming within the Paris Agreement target of 1.5°C. However, projects in development will remove only a fraction of this. The report says, “Without action to deliver 1 Gigatonne (Gt) of negative emissions globally by 2025, keeping global warming within the Paris Agreement target of 1.5°C cannot be achieved.”
