Allen's rule is a biological rule that says the limbs of endotherms are shorter in cold climates and longer in hot climates. Limb length affects the body's surface area, which helps with thermoregulation. Shorter limbs help to conserve heat, while longer limbs help to dissipate heat. [13]
Simplified control circuit of human thermoregulation. [8]The core temperature of a human is regulated and stabilized primarily by the hypothalamus, a region of the brain linking the endocrine system to the nervous system, [9] and more specifically by the anterior hypothalamic nucleus and the adjacent preoptic area regions of the hypothalamus.

Thermal pollution, sometimes called "thermal enrichment", is the degradation of water quality by any process that changes ambient water temperature.Thermal pollution is the rise or drop in the temperature of a natural body of water caused by human influence.
Beryl knocked out electricity to nearly 3 million homes and businesses at the height of the outages, which lasted days or much longer, and hospitals reported a spike in heat-related illnesses.
In 1950, the average American life span was 65 years, he pointed out during a panel he spoke at called “Navigating Longer Life Spans.” Today, it’s more like 77.5 years—an almost 13-year gain.
