In large, lowland tropical peatland basins that are less impacted by anthropogenic activities , the direct impact of climate change is that of a decreased carbon sink  . As for the temperate and boreal regions, climatic drying also tends to promote peat oxidation and carbon loss to the atmosphere   . In Europe, increasing mean annual temperatures in the Baltic, Scandinavia, and continental Europe  have led to widespread lowering of peatland water tables at intact sites , desiccation and die-off of sphagnum moss  and increased intensity and frequency of fires, resulting in a rapid carbon loss . Nevertheless, longer growing seasons and warmer, wetter climates have increased carbon accumulation and promoted thick deposits regionally, as reported for some North American sites  .
