Slowdown of AMOC ocean current may be gradual and reversible
Scientists worry that a surge of meltwater from Greenland could irreversibly collapse the Atlantic Meridional Overturning Circulation, but new modelling suggests the weakening of…

Europe’s heatwave is the hottest and most humid ever
The current temperatures in western and central Europe would have been virtually impossible 50 years ago, and unprecedented humidity levels make this heatwave especially…

Arctic Ocean reaches tipping point that could be dire for marine life
Disappearing sea ice is letting more sunlight in the Arctic Ocean and boosting phytoplankton growth, but this has depleted a crucial nutrient, which could…
