http://phys.org/news/2012-07-summer-glo ... tists.htmlSince Jan. 1, the United States has set more than 40,000 hot temperature records, but fewer than 6,000 cold temperature records, according to the National Oceanic and Atmospheric Administration. Through most of last century, the U.S. used to set cold and hot records evenly, but in the first decade of this century America set two hot records for every cold one, said Jerry Meehl, a climate extreme expert at the National Center for Atmospheric Research. This year the ratio is about 7 hot to 1 cold. Some computer models say that ratio will hit 20-to-1 by midcentury, Meehl said.

Americans dipped into the water, went to the movies and rode the subway just to be in air conditioning Saturday for relief from unrelenting heat that has killed at least 30 people across half the country.
The heat sent temperatures soaring over 38-degrees in several cities, including a record 40.5-degrees in Washington, St. Louis (41), and Indianapolis (40), buckled highways and derailed a Washington-area train even as another round of summer storms threatened.
The heat sent temperatures soaring in more than 20 states to 40.5-degrees in Louisville, Kentucky, 38.5 in Philadelphia, and 35 in New York; besides Washington, a record of 40-degrees was set in Sioux Falls, South Dakota, and Baltimore set a record at 39-degrees.
At least 30 deaths were blamed on the heat, including nine in Maryland and 10 in Chicago, mostly among the elderly. Three elderly people found dead in their houses in Ohio had heart disease, but died of high temperatures in homes lacking power because of recent outages, officials said. Heat was also cited as a factor in three deaths in Wisconsin, two in Tennessee and three in Pennsylvania.
Officials said the heat caused highways to buckle in Illinois and Wisconsin. In Maryland, investigators said heat likely caused rails to kink and led a green line train to partially derail in Prince George’s County, Maryland, on Friday afternoon. No one was injured, and 55 passengers were safely evacuated.
Thousands of mid-Atlantic residents remained without power more than a week after deadly summer storms and extreme heat struck the area, including 120,000 in West Virginia and some 8,000 in the suburbs around Baltimore and Washington, D.C. In the Washington area, the utility company Pepco asked customers to conserve power, saying the heat was stressing the system.
“This is becoming a black swan of heat waves, in the sense that it’s such a long heat wave, such a severe heat wave and encompassing such a large area,” said Chris Vaccaro, spokesman for the National Oceanic and Atmospheric Administration.
The wall itself can contain the pump, and I bet a clever engineer could use Earth's tidal forces to power some type of gravity pump. But more than just a wall, it could be a huge revenue generating device from both electrical power and tasty seafood from aquaculture.Blind groper wrote:Tyrannical
As I pointed out before, your "Great Wall" would also need to extend up every river and every tributary. Both sides.
I do not think you need 50 feet (15 metres). A few metres high would be enough, but the sheer length of it would seem staggering. A lot, lot more than 7,000 miles. Even then, there would have to be utterly and amazingly powerful pumps to clear all the rainwater that would be trapped behind that wall. Pumps the size of whole towns.
It's not surprising that it was an exceptional year. Most years only have 12 months.Gawdzilla Sama wrote:
