A study found that 9.4% of global deaths between 2000 and 2019 – ~5 million annually – can be attributed to extreme temperature with cold-related ones making up the larger share and decreasing and heat-related ones making up ~0.91% and increasing. Incidences of heart attacks, cardiac arrests and strokes increase under such conditions. [51] [52]

Desalination is a method of turning unusable saltwater into potable water. In a sense, it is transporting water from areas of high availability into low availability. Aqueduct systems do the same.
On the other hand, since 2002, water--strapped Southern Nevada, including Las Vegas, cut its use by 26% while adding 750,000 people—proof that measures like the Post-2026 Operational Guidelines ...
The decline in the death rate is due initially to two factors: First, improvements in the food supply brought about by higher yields in agricultural practices and better transportation reduce death due to starvation and lack of water. Agricultural improvements included crop rotation, selective breeding, and seed drill technology.
As multiple deadly wildfires burn across Los Angeles and hundreds of thousands of residents flee their homes, the lack of water is impeding firefighters' efforts to fight the flames.. More than ...
Mortality rates for African American children due to asthma are also far higher than that of other racial groups. [98] For African Americans, the rate of visits to the emergency room is 330 percent higher than their white counterparts. The hospitalization rate is 220 percent higher and the death rate is 190 percent higher. [96]
The effects of climate change on human health are profound because they increase heat-related illnesses and deaths, respiratory diseases, and the spread of infectious diseases. There is widespread agreement among researchers, health professionals and organizations that climate change is the biggest global health threat of the 21st century. [1] [2]
