The Earth is already operating beyond its capacity to sustainably support the global population, according to new research highlighting growing strain on food systems, climate stability, and human well-being. Despite this, researchers say that slowing population growth and increasing global awareness could still help reduce long-term risks.

Oil prices could jump to $200 per barrel and even higher if the Strait of Hormuz remains near-closed as it is at the moment, Fereidun Fesharaki, Chairman Emeritus of energy consultancy FGE NexantECA, told Bloomberg on Tuesday. Although the oil market is moving on sentiment and U.S. President Donald Trump’s social media posts about the war, the fact is that “every week, 100 million barrels of oil is not going through, and every month, 400 million barrels are not going through,” Fesharaki told Bloomberg Television.

Paul R. Ehrlich will be remembered as a scientist whose books about population and threats to the environment shaped the idea of limited growth in the modern era.

The Gulf Stream is part of the Atlantic Meridional Overturning Circulation (AMOC). The AMOC is a tipping element and may collapse under changing forcing. However, the role of the Gulf Stream in such a tipping event is unknown. Here, we investigate the link between the AMOC and Gulf Stream using a high-resolution (0. 1°) stand-alone ocean simulation, in which the AMOC collapses under a slowly-increasing freshwater forcing. AMOC weakening gradually shifts the Gulf Stream near Cape Hatteras northward, followed by an abrupt northward displacement of 219 km within 2 years. This rapid shift occurs a few decades before the simulated AMOC collapse. Satellite altimetry shows a significant (1993–2024, p < 0.05) northward Gulf Stream trend near Cape Hatteras, which is also confirmed in subsurface temperature observations (1965–2024, p < 0.01). These findings provide indirect evidence for present-day AMOC weakening and demonstrate that abrupt Gulf Stream shifts can serve as early warning indicator for AMOC tipping.

The decline in the health of nature around the world poses a threat to the UK's security and prosperity, an intelligence committee has concluded in a long-awaited report. The document warns of "cascading risks" from the degradation of some of the planet's most important ecosystems, including conflict, migration and increased competition for resources.
