They're still pumping and that study comes from 3 years ago.
Pumping is also raising the sea level and changing rain patterns.
Source?
Sea levels are rising due to ice caps melting, which are due to climate change. Whatever one deems for climate change it still exist.
Maybe not in some of our lifetime, if or when they fully melt many at current sea levels will be underwater.
Lets face some simple basic facts of life. Humans destroy almost everything on earth, including peace. Our demise will be of our own making.
Worse weather, rains, is due to warmer oceans, same reason ice caps are melting. When darker than white oceans are exposed to sun due to melting ice shelfs the faster they warm and accelerate melting. A spiral is in motion.
That said, more than one reason can be true at the same time. The warmer it is, the faster water evaporates, the more we pump, gotta have those big green lawns.
The aqua fields are not refilling because the grasses that were once there acted as a sponge and filtered the water into the aquas. In Nevada they figured this out and let some land return to being those sponges again. Even then, not keeping up and they ate pumping less.
Animals and native Americans had/have it right, take only what you need. Humans, especially Americans, are fat glutens, willing to destroy anything to have more.
Americans farm much more than they need for profit from other countries, to have more.
People should watch and learn from documentaries than news. News warns you, not much on educating.
