Given that agriculture, along with the deforestation associated with it, drives 24 percent of the world's
greenhouse gas emissions that cause
global warming, we are dependent upon farmers to do the heavy
lifting when it comes to fighting climate change.
In these, despite the various minor ups and downs, the general trend is down until about 1850 CE when anthropogenic effects really started
lifting the temperature, following the excess
global warming (so - called
greenhouse) gases.
