How was the climate change a factor in the agricultural revolution?

The English Agricultural Revolution began during a period of climate change in which temperatures decreased significantly. Lower temperatures meant less bacterial activity, a slower release of mineral nitrogen into cultivated soils, and a shorter growing season for crops—a combination that tended to diminish yields.

What are the main contributions to climate change?

Since 1970, CO2 emissions have increased by about 90%, with emissions from fossil fuel combustion and industrial processes contributing about 78% of the total greenhouse gas emissions increase from 1970 to 2011. Agriculture, deforestation, and other land-use changes have been the second-largest contributors.
