Arctic tundra is now warming world instead of cooling it

The tundra keeps burning and it’s transforming the Arctic
Fires, intensified by climate change, release carbon trapped in soil and plants. More frequent infernos have now transformed the tundra into a net source of carbon dioxide emissions. It’s a dramatic shift for the Arctic, and one that will make the planet even hotter.
Arctic tundra is now warming the world instead of cooling it
The news that the frigid Arctic tundra ringing the polar region has switched from being a net absorber, or "sink," of planet-warming greenhouse gases to a net emitter, or "source," indicates the Arctic is on the brink of further,
Arctic Tundra Has Long Helped Cool Earth. Now, It’s Fueling Warming.
Wildfires and thawing permafrost are causing the region to release more carbon dioxide than its plants remove, probably for the first time in thousands of years.
Arctic tundra is now a source – not a sink – of carbon emissions
For millennia, Arctic ecosystems have stored more carbon dioxide than they release, but that has shifted as warming temperatures have boosted wildfires and melted permafrost in the north
The Arctic just hit an unfortunate climate milestone
The last nine years have been the warmest ever recorded in the Arctic Circle, and this year saw a number of new milestones in the region: It was the rainiest summer on record, and plant life bloomed across the tundra at a near-record pace. As the Arctic ...
Sink to source: Arctic tundra emitting more carbon than it absorbs
After locking carbon dioxide in its frozen soil for millennia, the Arctic tundra is undergoing a dramatic transformation, driven by frequent wildfires that are turning it into a net source of carbon dioxide emissions,
Arctic Tundra Now a Carbon Source: 2024 Report Shows Stark Changes in Just Decades
The Arctic can feel like a far-off place, disconnected from daily life if you aren't one of the 4 million people who live there.
Thawing Tundra Is Now a Carbon Source in Fast-Warming Arctic
Scientists’ annual report card on the polar region finds that its vast tundra is releasing more CO2 than it stores, a worrying shift.
Arctic tundra is now a greenhouse gas emitter, federal report says
The shift from storing carbon dioxide to releasing it could have widespread implications for climate change, according to research from the Woodwell Climate Research Center in Falmouth published in NOAA's annual Arctic Report Card.
Arctic tundra now emitting more carbon gases than it absorbs, annual report says
For millennia, the tundra regions of the Arctic drew in carbon from the atmosphere and locked it in permafrost. That is the case no more, according to an annual report issued on Tuesday by the National Oceanic and Atmospheric Administration.
The Arctic tundra was a carbon sink. Now it contributes to global emissions
Wildfires and thawing permafrost are causing the Arctic region to release more carbon dioxide and methane than its plants remove.
Arctic tundra becoming a source of carbon dioxide emissions, NOAA warns
The Arctic tundra has historically helped reduce global emissions. But rising temperatures and wildfires in the region are ...

Arctic Tundra Has Turned From ‘Carbon Sink to Carbon Source’ in Dangerous Flip: NOAA
This is yet one more sign, predicted by scientists, of the consequences of inadequately reducing fossil fuel pollution,” said ...
