Antarctica's Melting Speed Doubles

Here's a couple of the stories we are covering this week on Renewable Now...http://www.renewablenow.biz/renewable-science.html.  Not all good news, obviously.  Get ready for a changing world.

If we needed more disturbing news on a melting Antarctica, scientists are supplying it. Days after we learned that the melting of the West Antarctica ice sheet is apparently unstoppable, researchers find that the continent is disappearing twice as quickly as it was when last measured. Information from Europe's CryoSat spacecraft show that Antarctic ice is now melting at a rate of 160 billion metric tons, or 176 billion short tons, per year, the BBC reports.

That rate will raise sea levels by about .017 inches yearly. Antarctica in its entirety, meanwhile, is dropping by about .79 inches per year. The new study focuses on data from the years 2010 to 2013; the previous data reflected the years 2005 to 2010. "We find that ice losses continue to be most pronounced in West Antarctica, along the fast-flowing ice streams that drain into the Amundsen Sea," says a researcher.

Extreme Drought  Causes Texans  To Turn
 
To Toilet Water

If you thought there wasn't a price to pay for climate change, just ask the folks living in Wichita Falls, Texas. After three years of severe drought, the city has imposed harsh restrictions that are forcing them to look for alternatives when it comes to their water needs.

We came across this interesting report on NPR and suggest that you take a look at it, this definitely has us wondering if this will also be our future, the world's future? Clean water is a necessity, it isn't like oil, or natural gas- we can live without those, but water is necessary. 

The city of Wichita Falls, Texas, may soon become the first in the country where half of the drinking water comes directly from wastewater.

Yes, that includes water from toilets.

The plan to recycle the water became necessary after three years of extreme drought, which has also imposed some harsh restrictions on Wichita Falls residents, says Mayor Glenn Barham.

"No outside irrigation whatsoever with potable water," he says. "Car washes are closed, for instance, one day a week. If you drain your pool to do maintenance, you're not allowed to fill it."

Barham says residents have cut water use by more than a third, but water supplies are still expected to run out in two years.

So the city has built a 13-mile pipeline that connects its wastewater plant directly to the plant where water is purified for drinking. That means the waste that residents flush down their toilets will be part of what's cleaned up and sent back to them through the tap.

Wichita Falls constructed a 13-mile pipeline to deliver the city's wastewater to a purification plant.


For some citizens, that's a little tough to swallow.

"I think it's gross," says Wichita Falls resident Marissa Oliveras. "I mean, it's recycled wastewater that we could possibly be drinking."

Oliveras isn't the only Wichita Falls resident who says she plans to switch to bottled water. At Gidget's Snack Shack downtown, customer Kira Smith also plans to spend extra money on bottled water when the recycled wastewater begins to flow.

"The thought of it definitely grosses me out," Smith says. "I'm sure that they would clean it and filter it up to standards, but I think just the idea would be — it's sort of a mindset kind of thing, you know what I'm talking about?"

The mayor insists the water will be clean and safe, and the city has undertaken a massive education campaign to explain the science behind the process, known as direct potable reuse. Several other Texas cities are pursuing the process. One small hamlet started recycling wastewater in 2011, but not on the scale that's being done here.

Some people unceremoniously call it "toilet-to-tap," but the city official overseeing this process, Daniel Nix, says that's not really how it works.

"The vast majority of water that enters a wastewater plant did not come from a toilet," he says. "They come from sinks, and bathtubs, and washing machines and dishwashers."
