Ocean losing ability absorb increasing carbon dioxide emissions
2014-09-10 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Sydney Morning Herald: Atmospheric levels of carbon dioxide are rising at a record rate as fossil fuel consumption increases and the ability of the oceans to absorb the greenhouse gas diminishes, the World Meteorological Organisation said. Average levels of C02 in the atmosphere rose almost 3 parts per million to 396 in 2013, accelerating from the 2.2 ppm increase in the previous year, the UN body said, citing data from 125 monitoring sites worldwide. "The changes we're seeing are really drastic," Oksana Tarasova,...

Global carbon dioxide levels at record high in 2013
2014-09-10 04:38:00| Climate Ark Climate Change & Global Warming Newsfeed
Associated Press: Carbon dioxide levels in the atmosphere reached a record high in 2013 as increasing levels of man-made pollution transform the planet, the U.N. weather agency said Tuesday. In an annual report, the World Meteorological Organization said that carbon dioxide, the heat-trapping gas blamed for the largest share of global warming, rose to global concentrations of 396 parts per million last year, the biggest year-to-year change in three decades. That's an increase of 2.9 ppm from the previous year...

Existing power plants will emit 300 billion tonnes of carbon dioxide in their lifetime: study
2014-08-28 01:00:00| Power Technology
The existing power plants worldwide will emit over 300 billion tons of carbon dioxide into the atmosphere in their lifetimes, according to a new study by Princeton University and the University of California-Irvine (UC Irvine).

Existing power plants will spew 300 billion more tons carbon dioxide during use
2014-08-26 22:32:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: Existing power plants around the world will pump out more than 300 billion tons of carbon dioxide over their expected lifetimes, significantly adding to atmospheric levels of the climate-warming gas, according to UC Irvine and Princeton University scientists. Their findings, which appear Aug. 26 in the journal Environmental Research Letters, are the first to quantify how quickly these "committed" emissions are growing -- by about 4 percent per year -- as more fossil fuel-burning power plants are...

Carbon dioxide 'sponge' could ease transition to cleaner energy?
2014-08-11 11:46:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: A sponge-like plastic that sops up the greenhouse gas carbon dioxide (CO2) might ease our transition away from polluting fossil fuels and toward new energy sources, such as hydrogen. The material -- a relative of the plastics used in food containers -- could play a role in President Obama's plan to cut CO2 emissions 30 percent by 2030, and could also be integrated into power plant smokestacks in the future. The report on the material is one of nearly 12,000 presentations at the 248th National...
