The critical Atlantic current system appears significantly more likely to collapse than previously thought after new research found that climate models predicting the biggest slowdown are the most realistic. Scientists called the new finding “very concerning” as a collapse would have catastrophic consequences for Europe, Africa and the Americas.

In response to global climate change, other systems, such as global oceanic circulations, could collapse, with devastating consequences. When it comes to battling climate change, some people think that the only issue we may be facing is that the climate may get a few degrees warmer. And, of course, if you live in rather cold areas on Earth, you wouldn’t mind some extra warmth. Even if you live in a temperate region, you may be inclined to think that 1.5 to 3 °C may not be such a big deal after all. […] But there is much more to climate change than warming temperatures. For example, in a previous story, I talked about how, by studying fossil records, we discovered the catastrophic chain of events following increased greenhouse gas emissions and global warming. The list goes on and on, from ocean acidification and anoxia to droughts and mass extinctions.

Existential Risk and Global Catastrophic - Risk: A Review

Dr Luke Kemp is a Research Associate at the Centre for the Study of Existential Risk, University of Cambridge. He has a PhD in international relations from the ANU and previous experience as a senior economist at Vivid Economics. This episode explores catastrophic and extinction risk, why the topic is understudied, and how we can weigh out the catastrophic risks of climate change and solar geo-engineering.

Unless global heating is reduced to 1.2C ‘as fast as possible’, warm water coral reefs will not remain ‘at any meaningful scale’, a report by 160 scientists from 23 countries warns

Breaching threshold would ramp up catastrophic weather events, further increasing human suffering

Morgan Stanley, JPMorgan and an international banking group have quietly concluded that climate change will likely exceed the Paris Agreement’s 2 degree goal.Top Wall Street institutions are preparing for a severe future of global warming that blows past the temperature limits agreed to by more than 190 nations a decade ago, industry documents show.

Thousands of Greenland's crystal-clear blue lakes have turned a murky brown thanks to global warming — and the worst part is that they've started emitting carbon dioxide. Record heat and rain in 2022 pushed the lakes of West Greenland past a tipping point, so rather than absorbing carbon dioxide (CO₂), they began to emit it into the atmosphere, according to a new study.

Climate projections versus population projections - There is a puzzling disconnect at the core of climate science between climate projections and population projections. Indeed, comparing the two, one might be forgiven for thinking that population scientists and climate scientists live in two completely different worlds.

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.
