Arctic Tundra Shifts to Source of Climate Pollution: NOAA Report Card

"NOAA scientists and affiliated researchers have documented profound change in the frozen north as U.S. government science itself faces an uncertain future."

"WASHINGTON—The icy region at the top of the globe, lashed by wildfire and pelted with increasingly heavy precipitation, has tipped into “uncharted territory,” scientists reported Tuesday.

The Arctic tundra has shifted from storing carbon in the soil to becoming a carbon dioxide source, the National Oceanic and Atmospheric Administration (NOAA) and its partner researchers concluded in their 19th annual Arctic Report Card.

As a result, the Arctic’s ability to help regulate Earth’s temperature is significantly compromised. Emissions from warming permafrost regions must be thought of as an increasing risk to a planet already being transformed by the overburden of fossil fuel pollution.

“This year’s report paints a clear and urgent picture of the Arctic’s evolving conditions,” said NOAA Administrator Richard Spinrad. “We are seeing impacts of warming in real time in the Arctic, and it’s a call to action.”"
