Every year during the summer, California experiences drought. The lack of water is hampering crops but is leading to the emergence of innovative projects such as WaterFX, which aims to pump precious liquid from the depths using solar energy. National Geographic tells us more about this company in an excerpt from the Inventing the Future series. The next episode will be broadcast tonight, Friday, February 26, 2016 at 9:30 pm.

The drought. Some might be tempted to say that Spain, like Portugal, is used to it. This is a job. But Researchers from the Institute of Oceanography Woods Hole (USA) today reported that the Iberian Peninsula hasn’t been this dry for over 1,000 years. in the question ,Azores high and the transformations it undergoes under the influence of global warming.

Remember that the azure typhoon is an elevated area the pressure that orbits over the North Atlantic. With great influences on weather report in Western Europe. The researchers found that this hurricane has changed dramatically over the past century. Even about 200 years ago it began to develop and expand. The trend has only accelerated. on the beat emissions From greenhouse gases.

devastating effects to come

Effects on weather report From this expansion of the Azores Anticyclone was especially recorded in stalagmites. 1200 years ago, winters in the western Mediterranean were drier and drier. According to the researchers’ projections, precipitation levels are expected to drop another 10 to 20 percent by the end of the century. Because as long as greenhouse gas emissions do not slow, the Azores will continue to expand.

The problem is that winter rains are particularly important to the environmental and economic health of Portugal and Spain. Without it, viable areas for viticulture could disappear, for example, almost completely by 2050. Olive production could drop by 30% by 2100.
