The Arctic tundra, long a carbon sink, is now a source of emissions, with recent wildfires contributing and further impacting climate change, says NOAA.
The 2024 Arctic Report Card highlights that the Arctic has been warming at up to four times faster than the global average for over a decade.
Dr. Sue Natali emphasizes the need for comprehensive knowledge of how climate changes will affect carbon dynamics in the Arctic to address this pressing crisis.
Rick Spinrad notes that increased temperatures lead to thawing permafrost, which releases stored carbon into the atmosphere, worsening climate impacts.
