The world's livestock are also expected to be affected by many of the same issues, from greater heat stress to animal feed shortfalls and the spread of parasites and vector-borne diseases. [5]: 746 The increased atmospheric CO 2 level from human activities (mainly burning of fossil fuels) causes a CO 2 fertilization effect. This effect offsets ...
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.
Agriculture and forestry face a triple challenge of limiting greenhouse gas emissions, preventing the further conversion of forests to agricultural land, and meeting increases in world food demand. [315] A set of actions could reduce agriculture and forestry-based emissions by two-thirds from 2010 levels.
World leaders are meeting in Paris this month in what amounts to a last-ditch effort to avert the worst ravages of climate change. Climatologists now say that the best case scenario — assuming immediate and dramatic emissions curbs — is that planetary surface temperatures will increase by at least 2 degrees Celsius in the coming decades.
Climate change will exacerbate current biotic stresses on agricultural plants and animals. [6] Increases of atmospheric carbon dioxide (CO 2), rising temperatures, and altered precipitation patterns will affect agricultural productivity. Increases in temperature coupled with more variable precipitation will reduce productivity of crops, and ...
[10] There are many strategies to reduce greenhouse gas emissions from agriculture (this is one of the goals of climate-smart agriculture). Mitigation measures in the food system can be divided into four categories. These are demand-side changes, ecosystem protections, mitigation on farms, and mitigation in supply chains.
