There are numerous effects of climate change on agriculture, many of which are making it harder for agricultural activities to provide global food security.Rising temperatures and changing weather patterns often result in lower crop yields due to water scarcity caused by drought, heat waves and flooding.

In the United States, agriculture is the second largest emitter of greenhouse gases (GHG), behind the energy sector. [1] 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.

This was then exceeded by millions of animal deaths during the 2007–2008 drought. [25] Climate change can impact livestock animals' food supply in multiple ways. First, the direct effects of temperature increase affect both fodder cultivation and productivity of rangelands, albeit in variable ways.
The state’s 2018 hazard mitigation plan lists a litany of both short-term and long-term impacts on agriculture. “Drought can increase unemployment, increase farm credit risk, capital ...
A drought is a period of drier-than-normal conditions. [1]: 1157 A drought can last for days, months or years.Drought often has large impacts on the ecosystems and agriculture of affected regions, and causes harm to the local economy.
Increased drought frequency and severity is also expected to be one of the effects of global warming. Drought having an acute economic impact in the history of the United States occurred during the 1930s and 1940s, periods of time known as 'Dust Bowl' years where relief and health agencies became overburdened and many local community banks had ...
In some areas Hurricane Gilbert overcame the drought outright, but other locations were at −6 or lower on the Palmer Drought Severity Index by early autumn 1988 and a general change in the pattern which had maintained for the preceding nine-plus months was required to ease the hydrological impacts of the drought. The agricultural damage was ...
