The climate and ecological crisis poses an unprecedented challenge, with scientists playing a critical role in how society understands and responds. This study examined how 27 environmentally concerned scientists from 11 countries construct the future in the context of climate change, applying a critical discursive psychology analysis. The degree to which the future is constructed as predetermined or transformable impacts both the urgency and scope of proposed actions. ...
A short definition of the polycrisis, including global environmental, geopolitical, and economic aspects.
In March 2022, a New York City-sized ice shelf collapsed in East Antarctica, long thought to be relatively stable against rapid change. The Conger-Glenzer ice shelf collapsed following decades of ocean-induced thinning, allowing its long-stabilizing features to transform into destabilizing ones.

The idea that the AMOC is headed to collapse is very controversial, but it is clearly weakening. If the circulation did collapse, the consequences on both sides of the Atlantic Ocean would be immense—including large changes in temperature and a spike in weather-related disasters.

The Atlantic Ocean's most vital ocean current is showing troubling signs of reaching a disastrous tipping point. Oceanographer Stefan Rahmstorf tells Live Science what the impacts could be.
The network of Atlantic ocean currents keeping the Earth's climate stable are far closer to collapse than first estimated, scientists warn.
AMOC collapse would bring severe global climate repercussions, with Europe bearing the brunt of the consequences.
Oceanographer Stefan Rahmstorf explains why Amoc breakdown could be catastrophic for both humans and marine life
If modern societies are breaking down, is there a political movement ready to soften the collapse and begin anew? Or do we need new ideas and organisations for collective action? Might a local focus be the only meaningful approach as industrial consumer systems decline? Or is this a period that calls for greater international solidarity with those suffering the most? I think the conversations and initiatives in the Francophone world will provide us many insights on these questions, for a number of reasons, which I’ll come to in a moment.
The average size of monitored wildlife populations has shrunk by 73% since 1970.

As a six-year investigation into the Thwaites glacier in Antarctica wraps up, the scientists involved are pessimistic for the future of this glacier and the consequences for sea level rise

Several studies in recent years have suggested the crucial system — the Atlantic Meridional Overturning Circulation, or AMOC — could be on course for collapse, weakened by warmer ocean temperatures and disrupted saltiness caused by human-induced climate change. But the new research, which is being peer-reviewed and hasn’t yet been published in a journal, uses a state-of-the-art model to estimate when it could collapse, suggesting a shutdown could happen between 2037 and 2064.

The Amazon rainforest is facing a barrage of pressures that might tip it into large-scale ecosystem collapse as soon as 2050, according to new research Wednesday warning of dire consequences for the region and the world. The Amazon, which holds more than 10 percent of the world's biodiversity, helps stabilize the global climate by storing the equivalent of around two decades of emissions of planet-warming carbon dioxide.
A crucial system of ocean currents may already be on course to collapse, according to a new report, with alarming implications for sea level rise and global weather — leading temperatures to plunge dramatically in some regions and rise in others. Using exceptionally complex and expensive computing systems, scientists found a new way to detect an early warning signal for the collapse of these currents, according to the study published Friday in the journal Science Advances. And as the planet warms, there are already indications it is heading in this direction.
Disruption of the Atlantic Meridional Overturning Current could freeze Europe, scorch the tropics and increase sea level rise in the North Atlantic. The tipping point may be closer than predicted in the IPCC’s latest assessment.

The new version of the “Seneca Effect” blog on Substack is doing reasonably well, so I thought it was time to prepare a page that explains what the Seneca Effect is and what it can teach us. (image by Dall-E) During the 1st Century AD, the Roman philosopher Lucius Annaeus Seneca observed the start of the disintegration of the Roman Empire. It was a process that would take a few more centuries to complete, but that was already evident to those who were willing to look beyond the surface of the still powerful Empire.

Societies and political structures, like the humans they serve, appear to become more fragile as they age, according to an analysis of hundreds of pre-modern societies.

World Meteorological Organization says 2023 will be hottest year on record, leaving ‘trail of devastation and despair’

Scientists warn of unlivable heat and food shortages after analyzing 35 planetary vital signs.
