A combination of rapid permafrost melt and lack of carbon absorption is turning swaths of Arctic tundra into a hotbed for CO2 emissions, says a new report.

A study carried out by 75 scientists in 12 countries and published in Nature Climate Change finds that levels of carbon released by permafrost melt are twice as high as previously thought and are outpacing the ability of tundra plants to absorb it.

More than 100 sensors planted in various locations across the Arctic show permafrost is releasing 1.7 billion tons of carbon into the atmosphere while Arctic plants - long thought to offset that release by absorbing emissions in the summer - are absorbing just 1 billion tons.

Scientists have been keying in on permafrost erosion like the kind seen above and now have evidence that the melt is releasing twice as much carbon into the atmosphere than previously thought

This is the first proof that tundra permafrost melt is now a net contributor to greenhouse gas emissions and a harbinger of increasingly adverse conditions in the region.

'There's a net loss,' Dalhousie University's Jocelyn Egan, one of 75 co-authors of a paper published in Nature Climate Change told CBC.

'In a given year, more carbon is being lost than what is being taken in. It is happening already.'

The international study realigns popular scientific thought on Arctic permafrost melt which posited that Arctic plants mostly mitigated carbon emitted during the winter when they flourished in the summer.

Not only are the plants failing to absorb carbon, but according to scientists, the pace of emissions is likely to increase.

Projections show that if global emissions remains static, that melting permafrost, which has long sealed-in carbon rich soil, may release 41 percent more carbon by the end of the decade.

As glaciers retract, they expose permafrost that has stored deep sinks of carbon. As that ice warms it releases greenhouse gases into the atmosphere and exacerbates climate change

Most projections show the world has failed to meet benchmarks for curbing emissions outlined by accords like the Paris Agreement.

Projections foreshadow a disconcerting future for an already-embattled Arctic.

Earlier this summer about 90 percent of the surface of Greenland’s ice sheet melted between July 30 and August 2, during which time an estimated 55 billion tons of ice poured off the island and into the ocean, according to the National Snow and Ice Data Center.

To help mitigate surface melt and its subsequent contributions to sea level rise, scientists have proposed increasingly elaborate solutions like using glass beads to reflect sun.
