The Climate Change Thread

Yanqing and Zhangjiakou, which are higher elevation venues, are cooler, with average high temperatures that peak above freezing and lows that fall to around -10 degrees Celsius at night.
"There have been recent technological advances that allow for the generation of snow when it is above freezing," explained Jordy Hendrikx, the director of the Snow and Avalanche Laboratory at Montana State University. "This is not your 'light fluffy' snow that you might think of -- it is much denser and not very soft."

They've been using snow machines at resorts in NA since I was a kid. Even here in NS we have at least two different ski hills with snow making equipment. The biggest challenge is the temperature. It is like very tiny frosty ice pellets to a degree. Not as slick as ice pellets but certainly not fluffy.

Extraordinary Antarctica heatwave, 70 degrees above normal, would likely set a world record

Scientists were shocked this month when Concordia Research Station in Antarctica reported a temperature 70 degrees above normal.

Scientists were shocked this month when a research station in Antarctica reported extraordinarily warm weather.​
​
The temperature at Concordia Research station atop Dome C on the Antarctic Plateau -- typically known as the coldest place on Earth -- surged to an astounding 11.3 degrees Fahrenheit on March 18.​
​
The normal high temperature for the day is around minus-56, which puts the March 18 reading at around 70 degrees warmer than normal.​
 
It's not just the Antarctic.

The North And South Poles Just Set Unbelievable Temperature Records

The North Pole and the South Pole set temperature records this week and this could have a major effect on our world as a whole
www.giantfreakinrobot.com www.giantfreakinrobot.com

As originally reported by The Washington Post (via Futurism), temperatures in the South Pole, in the eastern section of Antarctica rose in the range of 50 to 90 degrees more than normal

That’s because in the North Pole things were heating up as well. During roughly the same time period, temperatures there were up 50 degrees in spots which followed a bomb cyclone in the region. This rise in temps was going to bring that region closer to the freezing point, or melting point if you are a glass half empty kind of thinker.

If this kills the North Atlantic conveyor water mass flow it's a huge game changer.

And right on the heels of that comes this:

Lake Powell officials face an impossible choice in the West's megadrought: Water or electricity

Lake Powell, the country's second-largest reservoir, is drying up.
www.cnn.com www.cnn.com

Arizona (CNN)Lake Powell, the country's second-largest reservoir, is drying up.​
The situation is critical: if water levels at the lake were to drop another 32 feet, all hydroelectricity production would be halted at the reservoir's Glen Canyon Dam.​
​
The West's climate change-induced water crisis is now triggering a potential energy crisis for millions of people in the Southwest who rely on the dam as a power source. Over the past several years, the Glen Canyon Dam has lost about 16 percent of its capacity to generate power. The water levels at Lake Powell have dropped around 100 feet in the last three years.​
​
Bob Martin, deputy power manager for the Glen Canyon Dam, pointed toward what's called the "bathtub ring" on the canyon walls. The miles of white rock represent this region's problem.​

It's the one-two punch. Mead and Powell at the same time.

New government maps show nearly all of the West is in drought and it's not even summer yet: "This is unprecedented"

The latest government maps show 95% of California is suffering severe or extreme drought.

In an unprecedented move, Southern California officials declared a water shortage emergency and asked roughly 6 million residents to limit all outdoor watering to just once a week.

"We knew climate change would stress our water supplies and we've been preparing for it but we did not know it would happen this fast," said Gloria Gray, chairwoman of the Metropolitan Water District Board of Directors.
