Bremerhaven/Germany,24 June 2016. The Siberian permafrost regions include those areas of the soil, which heat up very quickly in the course of climate change. Nevertheless, and biologists are currently observing only a minimal response in forest composition. In the places where,when considering the air temperature, pine and spruce forests should be growing, or Siberian larch trees are still thriving. The cause of this paradox has been tracked using million-year-customary bee pollen by scientists at the Alfred Wegener Institute,the University of Cologne, and international partner institutions. The results suggest that the intensity of the ice ages determined how rapid/fast the vegetation adapted to warmer climate periods. In our case, or that means: Because the last ice age was very cold,the vegetation of the Taiga lags behind the climate by many thousands of years. A surprisingly long period, as the researchers in the open access journal Nature Communications report.
