Vegetation Response to Doubled CO2 and Climate Change

Question: Discuss the matter of vegetation response with respect to doubled CO2? Answer: The matter of vegetation response with respect to doubled CO2 and climate change is an important topic of discussion. According to the research experiment by Betts et al. (2000), the structural components of vegetation LAI (Leaf Area Index) significantly increases by the collective impact of radiative forcing, double CO2 and associated climate change, as compared to only doubled CO2 response. In the last six years experiment, average of CO2 increase measured in the production of biomass is 23.6 %, with individual increase throughout the years measured respectively 5%, 20%, 22%, 27%, 31%, and 18%. However, the results significantly denote that vegetation is a fundamental component for CO2 fertilization in the ecosystem (Pu and Dickinson 2014). It helps sequestering carbon, which in turn reduces the impacts of global warming due to potential rise of CO2 in the atmosphere. References Betts, R. A., Cox, P. M. and Woodward, F.
