Climate change 's hotter temperatures and society's diversion of water have been shrinking the world's lakes by trillions of gallons of water a year since the early 1990s, a new study finds. A ...
The United Nations' FAO states that by 2025 1.9 billion people will live in countries or regions with absolute water scarcity. It says two thirds of the world's population could be under stress conditions. [55] The World Bank says that climate change could profoundly alter future patterns of water availability and use.
[49] [50] Scientists realized over 30 years ago the ocean was a key fingerprint of human impact on climate change and "the best opportunity for major improvement in our understanding of climate sensitivity is probably monitoring of internal ocean temperature". [51] Marine organisms are moving to cooler parts of the ocean as global warming proceeds.
Human activities also increase the impact of climate change. Human activity has been linked to lake nutrition levels, which high levels are correlated to increasing vulnerability to climate change. Excess nutrients in water bodies, or eutrophication, can result in more algae and plant growth which can be harmful to humans, aquatic communities ...
Humans are the cause of the current mass extinction, called the Holocene extinction, driving extinctions to 100 to 1000 times the normal background rate. [ 119 ] [ 120 ] Though most experts agree that human beings have accelerated the rate of species extinction, some scholars have postulated without humans, the biodiversity of the Earth would ...
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 ...
As the negative consequences of rising global temperatures due to humankind's relentless burning of fossil fuels become more and more apparent in communities across the United States, anxiety over ...
Some lakes disappear because of human development factors. The shrinking Aral Sea is described as being "murdered" by the diversion for irrigation of the rivers feeding it. [citation needed] Between 1990 and 2020, more than half of the world's large lakes decreased in size, in part due to climate change. [71
