  • The Southwestern United States will Face Extremely Dry Weather by 2100

The prognosis is such that the Southwestern United States will probably face extremely dry weather by the end of 21st century due to rising temperatures.

Individuals living in the Southwest have had the nasty experience of facing droughts. Yet these parched conditions may be nothing when you compare them with what lies ahead during the course of this century.

A megadrought that will last not for a year or two but decades may come anytime in the 21st century. This would be a very big catastrophe that would shake up the economy of the United States.

A group of climate change scientists have calculated the risks involved with such an occurrence by the time we reach the year 2100, according to PopularMechanics.

It will most probably be a time of arid dryness where death of plants, crops and livestock will occur all across the land. It will also most likely last a generation.

We are looking at 35 years of constant aridity and drought which will bring the prospects of the region to their lowest point. If the current rate of production of greenhouse gases continues unabated, this is the most probable result which we will have to face whether we like it or not.

The chances of the megadrought are 70% to 99% depending on the precautions taken. The huge drought would probably span the length and breadth of the Southwest from San Francisco to Colorado to the Gulf of California.

It would be a man-made hell on earth and we would find it difficult to extricate ourselves from its clutches. The group of scientists published their findings Wednesday in the journal Science Advances.

Such megadroughts have occurred before and they can happen once again. History and prehistory both lend proof of the variation of the weather conditions.

If mankind was to really get down to business and curb pollution and global warming only then could a dent be made in this megadrought. In fact, all that will happen despite the best efforts is a 50% reduction in the ravaging effects of the megadrought.

While the very word “megadrought” may sound like a catchword meant for a movie, actually it is a very real concept that could happen anytime the weather goes haywire thanks to mankind’s interventionist ways.

Droughts have a long history behind them. Soil moisture, evaporation, heat and precipitation are the factors which tally in the megadrought equation.
