In 2021, a group of prominent permafrost researchers like Merritt Turetsky had presented their collective estimate of permafrost emissions, including the abrupt thaw processes, as part of an effort to advocate for a 50% reduction in anthropogenic emissions by 2030 as a necessary milestone to help reach net zero by 2050. Their figures for ...

A fire scar is seen outside Fairbanks, Alaska, in August 2022. Wildfire emissions and thawing permafrost have contributed to changes in the Arctic’s tundra, scientists say (NASA/Katie Jepson) ...
The Arctic tundra has become a source of emissions, rather than a carbon sink. The Arctic experienced its second-hottest year on record, according to a NOAA report. The Arctic tundra has become a ...
Melting permafrost in the Arctic is releasing toxic mercury into the water system, potentially impacting the food chain, scientists say. Arctic permafrost is melting at rapid rates, potentially ...
Walter Anthony's current research focuses on methane and carbon dioxide emissions from arctic and temperate lakes and wetlands in Alaska and Siberia, and the processes involved in greenhouse gas emissions from lakes, [10] including thermokarst [11] [12] (permafrost thaw), industrial plant emissions, geology, and changes in lake area. By ...
Extent and types of permafrost in the Northern Hemisphere as per International Permafrost Association. Permafrost (from perma- 'permanent' and frost) is soil or underwater sediment which continuously remains below 0 °C (32 °F) for two years or more: the oldest permafrost had been continuously frozen for around 700,000 years.
