🌍At least 15% of the Northern Hemisphere is covered by permafrost, which stores a massive amount of carbon.
❄️Thawing permafrost releases carbon that has been locked away for millennia, contributing to global warming.
🔄Tipping points could be reached, causing abrupt and widespread changes to the frozen ground.
☀️Thawing permafrost releases greenhouse gases, further amplifying global warming.
🌡️The Yedoma permafrost in the far north could release significant carbon at higher warming levels.
What is permafrost?
—Permafrost is ground that has been frozen for at least two years, storing a massive amount of carbon.
What are the consequences of permafrost thawing?
—Thawing permafrost releases carbon and other greenhouse gases, contributing to global warming and amplifying its effects.
What are permafrost tipping points?
—Permafrost tipping points are the thresholds at which the frozen ground undergoes abrupt and widespread changes.
How does permafrost thawing contribute to global warming?
—Thawing permafrost releases carbon and methane, potent greenhouse gases that further amplify global warming.
What is the Yedoma permafrost?
—The Yedoma permafrost is a deep deposit of carbon-rich soil found in parts of Siberia, Alaska, and Northern Canada.

02:18Thawing permafrost releases carbon that has been locked away for millennia, contributing to global warming.
03:27Tipping points in permafrost can result in abrupt and widespread changes to the frozen ground.
05:52Thawing permafrost releases greenhouse gases, creating a feedback loop that amplifies global warming.
08:50The Yedoma permafrost in the far north is deep and carbon-rich, potentially releasing significant carbon with higher warming levels.
