Antarctic sea ice changes affect clouds and oceans, making global warming stronger than earlier climate models predicted.

The widespread death of coral reefs is the first in a series of catastrophic and potentially irreversible tipping points the world may hit, according to a landmark report produced by 160 scientists across the world.

The latest report 'Global Tipping Points' warns that the planet has already surpassed the first "tipping point" of climate change: "It is a tragedy for nature and for the people who depend on it for their food and livelihood" .

One of the most potent greenhouse gas emissions has been discovered seeping out of cracks of the Antarctic sea floor, researchers have found.

Marine heatwaves can jam the ocean’s natural carbon conveyor belt, preventing carbon from reaching the deep sea. Researchers studying two major heatwaves in the Gulf of Alaska found that plankton shifts caused carbon to build up near the surface instead of sinking.

New scientific studies show coral reefs are under severe pressure from global warming, while ocean acidification poses a threat to marine life. Are politicians starting to listen?

A study published today in Earth System Dynamics provides a critical and previously underestimated connection between Antarctic sea ice, cloud cover, and global warming. This research is important because it shows that a greater extent of Antarctic sea ice today,

Rising levels of CO2 in the atmosphere may trigger a series of geological and biological processes that could ensure the next ice age arrives on time instead of being delayed, researchers say.
