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.
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
Arctic is now emitting more carbon than it absorbs: US agency
The Arctic tundra, which is experiencing warming and increased wildfire, is now emitting more carbon than it stores. Read more at straitstimes.com.
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 is emitting more carbon than it absorbs
"Our observations now show that the Arctic tundra, which is experiencing warming and increased wildfire, is now emitting more carbon than it stores, which will worsen climate change impacts," said NOAA Administrator Rick Spinrad. The finding is based on average of observations recorded from 2001-2020.
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 changing that, scientists say.
Arctic tundra now emits planet-warming pollution, federal report finds
Arctic tundra is releasing greenhouse gases into the atmosphere as hotter temperatures melt frozen ground and wildfires increase.
Arctic Now A Carbon Source Instead Of Carbon Sink, NOAA Says
The Arctic is now a carbon source, instead of a carbon sink, according to a new report released by NOAA. Watch to see how the Arctic is changing.
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,
Study: Warming has accelerated due to the Earth absorbing more sunlight
On Thursday, a group of German scientists—Helge Goessling, Thomas Rackow, and Thomas Jung—released a paper that attempts to ...

The Greenhouse Effect and How Humans Enhance It
The ground then radiates long wave infrared energy into the atmosphere which is then effectively absorbed by greenhouse gases. The greenhouse gases then go on to radiate that energy in all ...
