Plant growth is increasingly suffering from climate extremes

5. August 2021
Climate extremes such as droughts and heat waves lead to lower plant growth. This means that less CO2 is sequestered from the atmosphere. An international study led by the University of Augsburg and including Markus Reichstein from MPI-BGC shows that plant growth is especially reduced in the northern latitudes. This was concluded based on the fact that negative extremes in plant growth during the period 2000-2016 had increased by 10.6 percent when compared to the period 1982-1998. The results further indicate that especially grass and agricultural land covers are becoming increasingly susceptible to particularly warm droughts and that this negatively affects CO2 uptake by plants and agricultural outputs.
