The agriculture sector is sensitive to climate variability, [200] especially the inter-annual variability of precipitation, temperature patterns, and extreme weather events (droughts and floods). These climatic events are predicted to increase in the future and are expected to have significant consequences to the agriculture sector. [ 201 ]
In general, the preferred ambient temperature range for domestic animals is between 10 and 30 °C (50 and 86 °F). [3]: 747 Much like how climate change is expected to increase overall thermal comfort for humans living in the colder regions of the world, [6] livestock in those places would also benefit from warmer winters.

Climate change will affect agriculture and food production around the world. The reasons include the effects of elevated CO 2 in the atmosphere. Higher temperatures and altered precipitation and transpiration regimes are also factors. Increased frequency of extreme events and modified weed, pest, and pathogen pressure are other factors.
Livestock produces the majority of greenhouse gas emissions from agriculture and demands around 30% of agricultural freshwater needs, while only supplying 18% of the global calorie intake. Animal-derived food plays a larger role in meeting human protein needs, yet is still a minority of supply at 39%, with crops providing the rest.
Other observed effects also include the lengthening in growing seasons of certain agricultural crops such as wheat and maize. [33] A recently published study has used data recorded by the writer and naturalist Henry David Thoreau to confirm effects of climate change on the phenology of some species in the area of Concord, Massachusetts.

Climate change is altering global rainfall patterns. This affects agriculture. [95] Rainfed agriculture accounts for 80% of global agriculture. [96] Many of the 852 million poor people in the world live in parts of Asia and Africa that depend on rainfall to cultivate food crops.
Agrometeorology is the study of weather and use of weather and climate information to enhance or expand agricultural crops or to increase crop production. Agrometeorology mainly involves the interaction of meteorological and hydrological factors, on one hand and agriculture, which encompasses horticulture, animal husbandry, and forestry.
The negative impact of agriculture is an old issue that remains a concern even as experts design innovative means to reduce destruction and enhance eco-efficiency. [2] Animal agriculture practices tend to be more environmentally destructive than agricultural practices focused on fruits, vegetables and other biomass. The emissions of ammonia ...
