(Newser) – An "extreme" drought is already affecting 82% of California, researchers say, and 58% is facing an even worse "exceptional" drought—but perhaps the most worrying news deals with the possibility of a 30-year "megadrought." The odds of that occurring now range from 20% to 50% in the next 100 years, a Cornell University study finds. Such droughts may be "worse than anything seen during the last 2,000 years," experts say, per the Los Angeles Times.

"As we add greenhouse gases into the atmosphere … we are weighting the dice for megadrought," a researcher notes. And that could lead to migration that's never before been seen in the US, the Cornell Chronicle notes. Far higher is the risk of a 10-year drought, one comparable to what was seen during the Dust Bowl, the Times reports. The chances of that are 80%, and researchers point out that such lengthy dry spells occur about "once or twice per century." New Mexico and Arizona are also likely victims of extended drought, though there's some good news for Idaho, Montana, and Washington, whose risk of such a fate may shrink, experts say.

The time has come to create a network of salt marshes all across the USA. To help with sea level rise, the US can build a network of water pipes that connects a minimum of 30 states together to create these marshes. Then agriculture can adapt to using the sea water like they do in Qatar, UAE, etc. One product gained is sea salt which has a lot of beneficial properties. Some cities can choose to desalinate it and use it to help replenish recreational lakes and reservoirs. People who enjoy the use of the lakes can help pay for the operation. The main theme is to put the sea water to good use and then limit how much is sent back down the river systems. The US would essential be a huge sponge of sea water powered by solar, wind, gas, coal, and nuclear. Other nations could do the same and it is feasible we can theoretically absorb the entire melt of the poles which cannot be prevented but in reality its thousands of years away.

No mention of the hatred Americans have for the Creator of rain, and their love affair with immorality and corruption.

No more than TWO carpet crawlers for any couple, for population control and JAIL for conservative right-wing morons who have caused and then ignored GLOBAL WARMING!
