FRISCO — Global warming is likely to radically transform more than 80 percent of the Earth’s ice-free landscapes by the end of the century. boreal forests will be transformed into temperate savannas, trees will grow in the Arctic tundra and some of the world’s rainforests will disappear, according to a new study from the Potsdam Institute for Climate Impact Research.
“Essentially, we would be leaving the world as we know it,” said PIK scientist Sebastian Ostberg, describing the findings of a study published their results in Earth System Dynamics, an open access journal of the European Geosciences Union.
The researchers said “nearly no area of the world is free” from the risk of climate change transforming landscapes substantially, unless mitigation limits warming to around 2 degrees Celsius above preindustrial levels.
The profound transformations of land ecosystems have the potential to affect food and water security, and hence impact human well-being just like sea level rise and direct damage from extreme weather events. (more…)
