A study analyzing peat layers in Pawski Lug, Poland found that the transition from tribal to feudal living had a significant impact on the local ecosystem. The shift from small-scale forest burning to large-scale deforestation led to changes in plant composition and groundwater levels.
Even if human-induced greenhouse gas emissions are reduced to zero, global temperatures may continue to rise for centuries due to self-sustained melting of permafrost. To prevent projected temperature and sea level rises, all anthropogenic greenhouse gas emissions would need to be reduced to zero between 1960 and 1970.
