If global temperatures rise by 3 degrees Celsius, as much as the entire population in Brazil, China, Egypt, Ethiopia andGhana will be exposed to a severe drought lasting more than a year over a 30-year period.
There is a lack of water at Nicasio Reservoir.
The Climate Change study found that as temperatures rise, there will be more frequent and severe droughts in Brazil, China, Egypt, Ethiopia, Ghana, and India.
More than 50% of agricultural land in all six countries would be exposed to severe droughts lasting longer than a year if temperatures rise by 3 degrees Celsius.
With a global warming of 2 degrees Celsius, the risk of famine will double in Brazil and China, while a 1.5 degrees Celsius rise will triple the risk in Brazil and China.
According to Rachel Warren, lead study author and professor with the Tynd, global warming increases the amount of land exposed to dry weather, but only by 1.5 degrees.
Jeff Price said that limiting global warming to 1.5 degrees Celsius above pre-industrial levels would benefit all of the countries in the study.
Warren said that the research suggests that urgent global scale action is needed to stop deforestation and to decarbonize the energy system in this decade.
Some of the driest conditions on record have been experienced in the western U.S. over the past 20 years. A study from earlier this year found a 22-year period of dry weather in the American Southwest. Climate change has been blamed for the extreme conditions.
There are a lot of damaging effects on human life, the economy, and water storage and flows that can be caused by a dry spell. Crop growth can be affected by the weather. According to previous research, human-caused climate change can increase the likelihood of droughts. In Italy, the country's worst dry spell in decades caused its largest lake to near its lowest level ever recorded, while countries in the horn of Africa faced the worst dry spell in four decades. Carbon dioxide and other greenhouse gases caused by human activity trap heat near Earth's surface and will cause global temperatures to increase by anywhere from 1.1 to 5.4 degrees Celsius by the year 2200. The goal of the Paris Agreement is to limit global warming to 2 degrees Celsius in this century and 1.5 degrees compared to pre-industrial levels. The UN warned that countries must act now or never to limit global warming to 1.5 degrees.
How bad is the weather in the western part of the country? The study finds was the worst in 12 centuries. The New York Times is a daily newspaper in the United States.
Why are the rivers drying up. Waterways are turning to dust as a result of global dry spells.
