Greenpeace and local activists make their way through a Suzunsky forest next to the village of Shipunovo, 170 kms south from Siberian city of Novosibirsk on September 11, 2020, to extinguish a peat fire. - According to many scientists, Siberia and the Arctic are among the regions most exposed to climate change.

Peatland fires represent an additional threat to the climate because peat, when burning, releases a great deal of carbon dioxide. (Photo by Alexander NEMENOV / AFP)
