Farmers and Climate Change
Given their occupation, farmers are more vulnerable to the effects of weather than almost any other category of business, with the possible exception of an owner of a landscaping firm that also does snow removal during the winter. For some time, the climate change models have projected that not only will the average temperature worldwide increase persistently over the next several decades, it will also lead to greater variability of both temperature and precipitation in most regions of the world. For many years, some farm groups have embraced the notion that higher concentrations of carbon dioxide in the atmosphere would actually benefit their sector, as it could generate greater biomass growth and thus higher yields for certain types of crops. However, after extensive research, it is now clear that because higher carbon dioxide concentration will occur at the same time as higher temperatures and more variable precipitation as well as the limiting factor of availability of other plant nutrients, the net impact on crop yields from climate change will likely impact most parts of the world.
