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.

In 2020, a paper studied 538 plant and animal species from around the world and how they responded to rising temperatures. From that sample, they estimated that 16% of all species could go extinct by 2070 under the "moderate" climate change scenario RCP4.5 , but it could be one-third under RCP8.5, the scenario of continually increasing emissions.
According to the World Economic Forum, an increase in drought in certain regions could cause 3.2 million deaths from malnutrition by 2050 and stunting in children. [246] With 2 °C warming, global livestock headcounts could decline by 7–10% by 2050, as less animal feed will be available. [247]
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.
Children are particularly susceptible to health effects of climate change as their bodies are still developing. [88] [89] Rising global temperatures will expose them to unprecedented physical and psychological health risks. [90] [89] Children are more prone to heat stress because they cannot regulate their body temperature as effectively as ...
Some climate change effects: wildfire caused by heat and dryness, bleached coral caused by ocean acidification and heating, environmental migration caused by desertification, and coastal flooding caused by storms and sea level rise. Effects of climate change are well documented and growing for Earth's natural environment and human societies. Changes to the climate system include an overall ...
Livestock activities also contribute disproportionately to land-use effects, since crops such as corn and alfalfa are cultivated to feed the animals. [ 87 ] In 2010, enteric fermentation accounted for 43% of the total greenhouse gas emissions from all agricultural activity in the world. [ 88 ]
While North America’s record 134° F has stood for more than a century, Antarctica and Asia have set temperature records in the past decade.
