Direct GHG emissions from the agricultural sector account for 8.4% of total U.S. emissions, but the loss of soil organic carbon through soil erosion indirectly contributes to emissions as well. [2] While agriculture plays a role in propelling climate change, it is also affected by the direct (increase in temperature, change in rainfall ...
The effect of global climate change on yields of different crops from climate trends ranged from −13.4% (oil palm) to 3.5% (soybean). The study also showed that effects are generally positive in Latin America. Effects in Asia and Northern and Central America are mixed. [128]
Precipitation, especially rain, has a dramatic effect on agriculture. All plants need at least some water to survive, therefore rain (being the most effective means of watering) is important to agriculture. While a regular rain pattern is usually vital to healthy plants, too much or too little rainfall can be harmful, even devastating to crops.
The effects of climate change on the water cycle are profound and have been described as an intensification or a strengthening of the water cycle (also called hydrologic cycle). [2]: 1079 This effect has been observed since at least 1980. [2]: 1079 One example is when heavy rain events become even stronger.
The 2012–2013 North American drought, an expansion of the 2010–2013 Southern United States drought, originated in the midst of a record-breaking heat wave.Low snowfall amounts in winter, coupled with the intense summer heat from La Niña, caused drought-like conditions to migrate northward from the southern United States, wreaking havoc on crops and water supply.

According to the report of America's Pledge, 65% of the American population, 51% of the GHG emissions and 68% of the GDP, are now part of different coalitions that support climate action and want to fulfill the commitments of the US in the Paris Agreement.

Therefore, any comprehensive plan of adaptation to the effects of climate change, particularly the present and future effects of climate change on agriculture, must also consider livestock. [86] [87] Livestock activities also contribute disproportionately to land-use effects, since crops such as corn and alfalfa are cultivated to feed the ...
