AndrewFiese: The Colorado River Basin has lost as much groundwater as the entire volume of Lake Mead
Deep below the surface of the ground in one of the driest parts of the country, there is a looming problem: The water is running out — but not the kind that fills lakes, streams and reservoirs. Площадка кракен The amount of groundwater that has been pumped out of the Colorado River Basin since 2003 is enough to fill Lake Mead, researchers report in a study published earlier this week. Most of that water was used to irrigate fields of alfalfa and vegetables grown in the desert Southwest. No one knows exactly how much is left, but the study, published in the journal Geophysical Research Letters, shows an alarming rate of withdrawal of a vital water source for a region that could also see its supply of Colorado River water shrink. “We’re using it faster and faster,” said Jay Famiglietti, an Arizona State University professor and the study’s senior author. In the past two decades, groundwater basins – or large, underground aquifers – lost more than twice the amount of water that was taken out of major surface reservoirs, Famiglietti’s team found, like Mead and Lake Powell, which themselves have seen water levels crash. The Arizona State University research team measured more than two decades of NASA satellite observations and used land modeling to trace how groundwater tables in the Colorado River basin were dwindling. The team focused mostly on Arizona, a state that is particularly vulnerable to future cutbacks on the Colorado River. Groundwater makes up about 35% of the total water supply for Arizona, said Sarah Porter, director of the Kyl Center for Water Policy at Arizona State University, who was not directly involved in the study. The study found groundwater tables in the Lower Colorado River basin, and Arizona in particular, have declined significantly in the last decade. The problem is especially pronounced in Arizona’s rural areas, many of which don’t have groundwater regulation

Williamhok: These preppers have ‘go bags,’ guns and a fear of global disaster. They’re also left-wing
These preppers have ‘go bags,’ guns and a fear of global disaster. They’re also left-wing трипскан вход This fear is where Marlon Smith’s interest in preparedness began. Growing up in Trinidad, he lived through an attempted coup in 1990 that sparked his concern the government would not be there in times of disaster. This only deepened after he moved to New York City and watched the aftermath of 9/11 and then Hurricane Katrina. “You see the inability of the government to truly help their citizens,” he said. Smith, who now lives in New Jersey, runs a fashion company by day and spends his weekends teaching survival skills — including how to survive nuclear fallout. “People find it funny that I work in women’s evening wear and yet I do this hardcore prepping and survivalism in the woods,” he said. https://tripscan.biz tripscan войти It’s hard to pin down the exact number of preppers in the US. Mills says 5 million is a reasonable estimate; others would say much higher. Chris Ellis, a military officer and academic who researches disaster preparedness, puts the figure at around 20 to 23 million using data from FEMA household surveys. Figuring out the proportion of preppers on the left is perhaps even trickier. Mills, who has surveyed 2,500 preppers over the past decade, has consistently found about 80% identify as conservatives, libertarians or another right-wing ideology. He doesn’t see any dramatic upswing in left-wing preppers. necdotal evidence, however, points to increased interest from this side of the political spectrum. Several left-wing preppers told CNN about the burgeoning popularity of their newsletters, social media channels and prepping courses. Shonkwiler says subscriber numbers to his newsletter When/If increase exponentially whenever right-wing views make headlines, especially elections. He saw a huge uptick when Trump was reelected. Smith has noticed more libera
