Scientists predict intensified droughts especially for the Southwest parts of the United States. A new study accounts for this situation in the future years of our century. The only solution to prevent these phenomena is severely reducing the gas emissions which lead to rising temperatures and accelerate the process of global warming.
The regions in the Southwest of the United States experienced droughts before. However, specialists warn that even more intensified droughts are due to the following years. They say that it will be quite different from everything experienced before.
The researchers who conducted the study used computer simulators to predict the effects of climate change on the atmosphere. Their findings show that there are more than seventy percent chances that intensified droughts will hit the Southwest of the United States.
These results are based on a climate featuring rising temperatures, but a normal level of precipitations. However, if rain is also affected, the areas will be even drier. The chances of an intensified drought soar to ninety-nine percent.
Specialists also took into consideration the decision at the Paris agreement. World organizations decided to prevent global temperatures from going higher than two degrees Celsius, which is approximately 3.6 degrees Fahrenheit. In order to do that, gas emissions should be curbed. The pollutant gasses released into the atmosphere originate mainly from burning oil and coal.
According to the scientists’ estimation, such a measure would reduce the risk of intensified droughts. If the rules of the Paris agreement are obeyed by all the countries involved, there would be about forty percent chances to experience such droughts.
Droughts bring the lowering of water levels in rivers. Researchers are concerned about the Colorado River, which has been experiencing low levels for more than a decade. This should draw the attention of authorities in charged with water conservation strategies.
California is also one of the regions severely affected by droughts. The last six years were characterized by dryness, which took its toll on crops and rivers basins.
The risk of intensified droughts is real, as experts announce us. Previous reports show that the dry phenomena lasted for at least two decades in several parts in the Southwest. However, specialists warn that what is ahead of us is much worse that what we might expect. So equally worse consequences are to come.
The new study documenting the high possibility of intensified droughts was published in Science Advances on October 5.
