Plant gasses possibly dampen the temperature rise in Greenland. Plants emit compounds to deter pests or attract pollinators, and as a side effect particles are formed when the compounds interact in the air. These particles can contribute to the formation of clouds, which reflect incoming solar radiation, and thus prevent solar heat from reaching the ground and warming it additionally. Researchers from the University of Copenhagen have studied the effect of the imminent climate changes on the release of so-called "biogenic volatiles" to the atmosphere above Greenland. http://www.lifeyes.com/articles/1074/20160405/plant-gases-counteract-arctic-climate-change.htm Paper: http://www.nature.com/ngeo/journal/vaop/ncurrent/full/ngeo2692.html
