Greenland’s ice sheet is rapidly melting in areas previously believed to be stable, leading to accelerated rises in global sea levels, according to a study published Sunday. http://www.usatoday.com/story/news/nation/2014/03/16/northeast-green ...

Researchers have developed an app for people to submit readings from Secchi disks - a method used since 1865. http://www1.plymouth.ac.uk/marine/secchidisk/Pages/default.aspx The team hopes the data will help them understand what is happening beneath the waves. They have been &quot;astonished&quot; by the response so far but are hoping for more readings from the ...

The French capital region and 30 other departments have been on maximum pollution alert for several days. Landmark buildings like the Eiffel Tower were barely visible after a white fog settled over Paris. The capital's air quality has been one of the worst on record, French environmental agencies say. A lack of wind, combined with cold nights ...

By the way, if Brazil had not built the Itaipu, the Sao Paulo area would now be either without power or surrounded by fossile fuel plants and with air quality like Beijing. Power plants of any technology recover their costs only slowy, and obviously interest rates as high as in countries below investment grade do not help either. Should these countries ...

Every year, Moscow produces about 9 million tonnes of rubbish - a fifth of all the waste produced in Russia - which goes to 38 landfill sites on the edges of the city. In Dyakovo, a town next to the Dmitrovsky dump, the soil is so contaminated that vegetables will not grow there, the Moscow Times reports. http://www.themoscowtimes.com/busi ...

Do they ever really make sense? A peek over the edge of the Hoover Dam's 60-storey wall is enough to send shivers down anyone's spine. Constructed from enough concrete to pave a motorway from New York to San Francisco - this colossal barrier is touted as a symbol of man's mastery over ...

Global demand is projected to increase by 70 percent to feed a population estimated to reach 9.6 billion by 2050. http://www.fao.org/ag/againfo/themes/en/animal_production.html Much of the growth in demand is being supplied through rapidly expanding modern forms of intensive livestock production, but traditional systems continue to exist in ...

Hundreds of refuse workers protested at the mayor's office on Friday demanding better pay and working conditions. Authorities said on Monday that they had reached an agreement with union leaders and expected normal collection to be resumed within days. But many workers say the union is not representing their interests. The president of Rio's rubbish ...

It is the first Chinese firm ever to default on its onshore corporate bonds. On Tuesday, the firm warned it would be unable to make a 89.8 million yuan (&#x0024;14.6m) interest payment on a one billion yuan bond issued in 2012. The default is seen as a test case for the Chinese government. Investors have assumed in the past that the Chinese government would bail out any Chinese ...
