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.

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 ...
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.
Climate-smart agriculture (CSA) (or climate resilient agriculture) is a set of farming methods that has three main objectives with regards to climate change. [ 1 ] [ 2 ] Firstly, they use adaptation methods to respond to the effects of climate change on agriculture (this also builds resilience to climate change ).
Research in New Zealand estimated that switching agricultural production towards a healthier diet while reducing greenhouse gas emissions would cost approximately 1% of the agricultural sector's export revenue for New Zealand, which is an order of magnitude less than the estimated health system savings from a healthier diet.

Extreme weather events affect public health, and food and water security. [239] [240] [241] Temperature extremes lead to increased illness and death. [239] [240] Climate change increases the intensity and frequency of extreme weather events. [240] [241] It can affect transmission of infectious diseases, such as dengue fever and malaria.
Unless the emissions of GHGs are curbed significantly, their concentrations will continue to rise, leading to changes in temperature, precipitation, and other climate variables that will undoubtedly affect agriculture around the world. Climate change has the potential to increase weather variability as well as gradually increase global ...
