Greenland Ice Cores Reveal Climate Tipping Points from Last Ice Age

New research uncovers abrupt climate changes linked to the Atlantic Meridional Overturning Circulation, raising concerns for future global warming impacts.

Ice core samples from Greenland provide data spanning 120,000 years, highlighting abrupt climate changes known as Dansgaard-Oeschger events.
These events are tied to rapid shifts in the Atlantic Meridional Overturning Circulation (AMOC), affecting global weather patterns.
The AMOC's instability caused significant cooling in Europe and disrupted monsoons in Asia during the last Ice Age.
Current climate models suggest the AMOC may weaken again due to global warming, potentially impacting billions worldwide.
The study's findings emphasize the importance of understanding climate tipping points to prevent catastrophic and irreversible changes.
