STOCKHOLM, Aug 24 (Thomson Reuters Foundation) - The world needs to use water more efficiently rather than exhausting invisible underground supplies and blindly exporting "virtual water" to avert a global crisis that would undermine food and energy systems, a leading expert warned.

More than one-third of humanity is water-stressed every year or season, while drought crises are on the rise from California to Ethiopia as the planet warms, said Fred Boltz, who leads The Rockefeller Foundation's work on science and environment. ...

As recently as the 1980s, gray seals effectively were extinct on Cape Cod. So when researchers announced last week that the population there has recovered not to 15,000 gray seals, the previous official estimate, but to as many as 50,000, it was dramatic evidence of how quickly conservation sometimes can work. ...

"When you imagine people living densely packed, you may think of New York City. But a new report from the Census Bureau shows California is home to the most densely populated metro areas in the United States," according to KPBS.
 
That ranking takes the population of the entire metropolitan area, and divides it by the land area of the entire metropolitan area, to provide a summary figure for the metro area (not the city).

(CNN)By the end of the century, the global temperature is likely to rise more than 2 degrees Celsius, or 3.6 degrees Fahrenheit.
 
This rise in temperature is the ominous conclusion reached by two different studies using entirely different methods published in the journal Nature Climate Change on Monday.
 
One study used statistical analysis to show that there is a 95% chance that Earth will warm more than 2 degrees at century's end, and a 1% chance that it's below 1.5 C.
"The likely range of global temperature increase is 2.0-4.9 [degree
