In the coldest place on Earth, the temperature is rising.
The researchers assessed the amount of black carbon present in snow collected across a 1,200-mile stretch of Antarctica.
Union Glacier is also where the Antarctic marathon takes place each summer.
Across four summer seasons between 2016 and 2020, they nabbed 155 snow samples at 28 different sites.
The samples revealed black carbon concentrations “considerably above” those found in unoccupied regions of the continent.
The Antarctic peninsula showed the highest concentrations, with the Trinity peninsula showing the highest levels of soot.
Worryingly, even the sampled region near Union Glacier was showing signs of increased black carbon.
