JD Vance was supposed to be the inconsequential vice-president. But his starring role in Friday’s blowup between Donald Trump and Volodymyr Zelenskyy – where he played a cross between Trump’s bulldog and a tech bro Iago – may mark the moment that the postwar alliance between Europe and the US finally collapsed.

EDF a passé une dépréciation pour 900 millions d'euros sur le projet éolien en mer Atlantic Shores, aux États-Unis, auquel participait le groupe français au sein d'une coentreprise avec Shell, a-t-il indiqué vendredi, après l'annonce d'un gel des permis d'exploitation par Donald Trump.

That’s now how separation of powers works under the U.S. Constitution.

The problem of waste that really needs fixing is not the public employees but the private contractors—and Elon Musk is one of them.

Global warming is moving faster than the best models can keep a handle on.

Several high-profile research papers have brought renewed attention to the potential collapse of a crucial system of ocean currents known as the Atlantic Meridional Overturning Circulation, or AMOC, as we discussed in part one of this two-part post. Huge uncertainties in both the timing and details of potential impacts of such a collapse remain.

On why collapse could be much closer than predicted: what happens when the Atlantic Ocean’s heart stops beating?

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.

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.

A new study suggests that the Gulf Stream was stronger during the last ice age due to more powerful winds, indicating that future changes in wind patterns could weaken the Gulf Stream, affecting European climate and North American sea levels. This research enhances our understanding of the Atlantic Meridional Overturning Circulation (AMOC) and its vulnerability to climate change.

An international team of scientists has warned against relying on nature providing straightforward 'early warning' indicators of a climate disaster, as new mathematical modeling shows new fascinating aspects of the complexity of the dynamics of climate. It suggests that the climate system could be more unpredictable than previously thought.

RealClimate: A new paper was published in Science Advances today. Its title says what it is about: "Physics-based early warning signal shows that AMOC is on tipping course." The study follows one by Danish colleagues which made headlines last July, likewise looking for early warning signals for approaching an AMOC tipping point (we discussed it here),

Scientists now have a better understanding of the risks ahead and a new early warning signal to watch for.

Collapse in system of currents that helps regulate global climate would be at such speed that adaptation would be impossible

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.

Wereldnieuws was het de laatste weken. ‘De Golfstroom kan stilvallen in 2025’, kopten kranten naar aanleiding van een recent verschenen paper. In feite ging de publicatie niet over de Golfstroom, maar over de Atlantic Meridional Overturning Circulation, kortweg AMOC. En bij de genoemde termijn vallen ook vraagtekens te plaatsen. Wat zegt de wetenschap over al die amok rond de AMOC? ‘Of het nu in 2025 is of in 2100, we willen niet dat dit gebeurt.’
