Southern Ocean may flip from carbon sink to carbon source under mitigation scenarios
Plans to limit the global temperature rise to 1.5°C above preindustrial levels depend on reaching net-zero emissions and, in many cases, actively removing carbon dioxide (CO2) from the air. While this helps limit extreme ...
