The drought in the southwest of the US will probably last the rest of the 21st century and possibly further if global warming shifts the distribution of heat in the Pacific, according to a study published last week under the leadership of researchers at the University of Texas in Austin.
With the help of sediment cores collected in the Rocky Mountains, Paleoclimatology Records and Climate Models, the researchers found global warming driven by greenhouse gas emissions can turn patterns of atmospheric and marine heat into the north -quiet Osceage that looks like the negative phase of the negative phase of the negative phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase phase. Fluctuations in the winter temperatures in the American winter temperatures in the American winter temperatures in the American winter temperatures in the American winter temperatures in American winter temperatures in American winter temperatures in the American winter temperatures in the American winter temperatures in the American winter temperatures. But in this case the phenomenon can take much longer than the usual 30-year cycle of the PDO.
“If the temperature patterns of the sea surface temperature in the northern Pacific Ocean were only the result of processes related to stochast [random] Variation in The Past Decade or Two, we would have just leg extremely unlucky, like a really bad roll of the dice, ”Said Victoria Todd, The Lead Author of the Study and a PhD student in Geosciences at Hypothesis at Austin. Surface Temperatures in the North Pacific, This Will Be Sustained Into The Future, And We Need To Start Looking At this As A Shift, Instead or Only the result of bad luck. '
The southwestern US is currently experiencing a megaDrough that results in the dorification of the landscape, drying for decades from the region caused by climate change and the over -consumption of the water of the region. This has led to large rivers and their basins, such as the Colorado and Rio Grande rivers, which reduced flows and a decrease in water stored in underground water -bearing layers that forces states and communities to take into account a greatly reduced water supply. Farmers have cut back on the amount of water they use. Cities are looking for new water stocks. And states, tribes and federal agencies are involved in tense negotiations on managing decreasing resources such as the Colorado River in the future.
