A study claims the Atlantic meridional overturning circulation is weakening more than than once believed. Experts say its findings are far from the final word.

Some climate simulations indicate that a weakened AMOC could reduce monsoon rainfall over parts of India, especially central and northwestern regions. Others suggest rainfall may become more uneven — with longer dry spells interrupted by bursts of intense rain.

Ocean sensors detect weakening in Atlantic circulation, highlighting possible long-term effects on climate and marine ecosystems.

The Atlantic Meridional Overturning Circulation (AMOC) is a large-scale and delicate system of ocean currents, responsible for our warm climate.

Most of the microlitter present in the South Atlantic Ocean originates from the West African coast and is particularly concentrated in areas near the equator and off the coast of Brazil, according to a study appearing in Environmental Pollution.

Atlantic bluefin tuna, the largest of all tuna species, declined precipitously toward commercial collapse in the early 2000s after decades of overfishing. The species has since rebounded across most of its range,
