The Taliban's return to power in Afghanistan has led to the erasure of women from public life. There’s a UN-led campaign to recognise it as “gender apartheid”, but the international community is divided and lacking leverage.

Complex ocean currents keep Europe warm and bring rain to Africa, but could they come to an end?

The Atlantic Meridional Overturning Circulation (AMOC) is a system of ocean currents within the Atlantic Ocean, transporting warm water north towards the Arctic and returning cold water south towards Antarctica. The Gulf Stream is a component of AMOC, which carries warm water from the Gulf of Mexico, up along the eastern coastline of the United States.

AMOC’s currents are driven by changes in water density due to changes in ocean salinity and temperature. Increasing ocean temperatures and freshwater flows from melting ice sheets due to climate change, have the potential to weaken AMOC. This could lead to cooler temperatures in Europe and a drop in rainfall in key agricultural areas in places like Africa and Asia, in turn affecting millions of people.
