Climatologists predict that powerful drought

American scientists analyzed the history of droughts over the last two thousand years and stated that in the West and South-West of the United States at any moment can start a drought that will last at least 30 years. The researchers ‘ findings were published in the Journal of Climate.

Starting in 2011, in the southern regions of the United States raging drought that affected 98% of the population of California and almost all of its forests, many of which are almost completely dried up during this time. To combat it, California authorities took a very severe restrictive measures, which are comparable to the draconian restrictions on water consumption during a drought in the 1970-ies, which were articulated but not applied in practice.

Scientists estimate that only in the last five years, California has lost about 67 cubic kilometers of water, and before the onset of “hurricane” at the end of December last year, the situation was fast approaching critical. After a series of powerful rain in January, the state government announced the completion of the drought, but climate scientists fear that the situation could again change.

In the study, researchers created a set of climate models, in which the birth of droughts drove or disasters, or climatic fluctuations, and have compared the results of calculations that showed paleoclimatic data. Climatologists were interested not in the time and place of the occurrence of a specific drought, and their frequency, timing, and the number of small and big events of this kind.

As shown by these calculations, major droughts occur mainly due to random fluctuations in the Earth’s climate, but some of their properties depend on external events, for example, the probability that several major droughts will start almost at the same time and reinforce each other’s action.

All of this suggests that a powerful drought, ongoing for 30 years, can occur in the Western United States, even if the planet’s climate will not change in the future. Such disasters, as they note, affect the territory of many States and their authorities should be prepared that such problems can occur in any of the following summer or winter season.
