World’s permafrost gets warmer; Siberia rises the most
Scientists say the world’s permafrost is getting warmer, with temperatures increasing by an average of 0.3 degrees Celsius (0.54 Fahrenheit) over a decade.
A study published Wednesday found the biggest rise in Siberia, where frozen soil temperatures rose by 0.9 degrees Celsius (1.62 Fahrenheit) between 2007 and 2016.
Scientists say the increases track global warming generally. They noted that thawing permafrost — already recorded at five of the sites — contains organic matter that can release greenhouse gases, further stoking climate change.
