Storm made landfall up North. Prayers to them.

Still dealing with wind, rain and the threat of tornadoes down here. Probably out of the woods by happy hour.

People came over. We ended up with a hurricane party. Only solids consumed were ice cubes.

Burgers tonight!

We're of course on the very outer most fringes, clouds, rain expected this PM, nothing at all major fortunately.  Had it blipped north maybe tornadoes might have been at issue.  South Georgia is another story, I hope not a bad one of course.

This is from the NYT, but I suspect it's basically correct, and worrisome:


he water that lies beneath the earth’s surface — known as groundwater — has been a vital resource for thousands of years. Communities that are far away from lakes and rivers use groundwater to irrigate crops and provide drinking water.

For most of human history, groundwater has existed in a convenient equilibrium. The pockets of water under the surface need years or decades to replenish as rainwater and other moisture seep into the earth. Fortunately, though, people have used groundwater slowly, allowing replenishment to happen.
Now that equilibrium is at risk.
Several of my colleagues — led by Mira Rojanasakul and Christopher Flavelle — have spent months compiling data on groundwater levels across the U.S., based on more than 80,000 monitoring stations. Chris and Mira did so after discovering that no comprehensive database existed. The statistics tended to be local and fragmented, making it difficult to understand national patterns.
The trends in this new database are alarming. Over the past 40 years, groundwater levels at most of the sites have declined. At 11 percent of the sites, levels last year fell to their lowest level on record.
The U.S., in other words, is taking water out of the ground more quickly than nature is replenishing it. “There’s almost no way to convey how important it is,” Don Cline, the associate director for water resources at the United States Geological Survey, told The Times.
Already, there are consequences. In parts of Kansas, the shortage of water has reduced the amount of corn that an average acre can produce.
Sources: U.S.D.A., U.S.G.S., Kansas Geological Survey | By The New York Times
In Norfolk, Va., officials have resorted to pumping treated wastewater into underground rock layers that store groundwater — known as aquifers — to replenish them. On Long Island, the depletion of aquifers has allowed saltwater to seep in and threatened the groundwater that remains.
“We’ve built whole parts of the country and whole parts of the economy on groundwater, which is fine so long as you have groundwater,” Chris told me. “I don’t think people realize quite how quickly we’re burning through it.”
Giant wells
Unlike many other environmental trends, this story is not primarily about climate change, although the warming planet plays an aggravating role. There are three main reasons for the groundwater declines:
  • Pumping technology has improved, allowing communities to draw water out of the earth much more quickly than in the past. Some wells can pump more than 100,000 gallons a day.
  • Economic growth and urban sprawl have increased the demand for water. Although the U.S. economy has not been growing rapidly in recent decades, American farms help feed other countries where the economy and population have been growing faster.
  • Climate change has reduced the amount of water that comes from alternative sources, like rivers: A warmer planet leads to less rainfall and faster evaporation of the rain that does fall. These declines have led communities to increase groundwater use.
These forces are not unique to the U.S. Other countries are coping with groundwater declines that are sometimes worse. This summer, my colleagues Vivian Yee and Leily Nikounazar reported on the dire shortages in parts of Iran, while Alissa Rubin and Bryan Denton did so in Iraq. The photographs and videos from Iraq are especially jarring.

One bit of this confuses me...

  • Climate change has reduced the amount of water that comes from alternative sources, like rivers: A warmer planet leads to less rainfall and faster evaporation of the rain that does fall. These declines have led communities to increase groundwater use.

If water evaporates due to warming, it goes into clouds, which then drop it back on the planet as rain. If it evaporates more quickly and becomes clouds again, it drops back onto the planet as rain again. 

I can see an argument that a warming planet perhaps will lead to changing weather patterns and localized droughts in areas that didn't have them historically, but I don't understand how this leads to seemingly less total rainfall on the planet if water is evaporating into the atmosphere more easily. 

It doesn't make any sense to me whatsoever. 

If I'm wrong, I welcome someone trying to educate me on how this works.

The hydrologic cycle is always balanced. The amount of water never changes. All that changes is where the water is at a given time.

I don't call that article very good at all.

I can see that warmer temperatures mean more water vapor in the atmosphere overall, absolute humidity would increase.  I don't know how large a factor that is.

The Ogallala Aquifer is the largest aquifer in the United States and is a major aquifer of Texas underlying much of the High Plains region. The aquifer consists of sand, gravel, clay, and silt and has a maximum thickness of 800 feet. Freshwater saturated thickness averages 95 feet.

Seems a bit odd since this area gets relatively little rain compared to just East of there

The Ogallala Aquifer: Saving a Vital U.S. Water Source
The massive underground water source feeds the middle third of the country but is disappearing fast. Can it be conserved?

Pretty busy in the Atlantic right now. September 10 is peak season. Gonna keep my eye on the one Africa just tossed out there.

There are growing signs of public disenchantment in the shift to a more sustainable Europe, with a so-called “greenlash” emerging as people feel the cost impacts.
