Carbon concentration in our atmosphere hits grim milestone
2016-06-13 19:22:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: A new study suggests carbon dioxide will never fall below 400 ppm this year, nor next, nor the next. Scientists who measure and forecast the concentrations of greenhouse gases in the atmosphere said Monday that we may have passed a key turning point. Humans walking the Earth today will probably never live to see carbon dioxide concentrations in the atmosphere once again fall below a level of 400 parts per million (ppm), at least when measured at the iconic Mauna Loa Observatory in Hawaii, where...

Arctic Ocean methane does not reach the atmosphere
2016-05-30 04:02:00| Climate Ark Climate Change & Global Warming Newsfeed
ScienceDaily: 250 methane flares release the climate gas methane from the seabed and into the Arctic Ocean. During the summer months this leads to an increased methane concentration in the ocean. But surprisingly, very little of the climate gas rising up through the sea reaches the atmosphere. "Our results are exciting and controversial," says senior scientist Cathrine Lund Myhre from NILU -- Norwegian Institute for Air Research, who is cooperating with CAGE through MOCA project. The results were published...

What would happen to the atmosphere if we burned all our fossil fuels?
2016-05-29 23:12:00| Climate Ark Climate Change & Global Warming Newsfeed
Stuff: An 8C rise would occur if we kept burning fossil fuels, which would change the face of the planet, a climate scientist says. Q: What would happen to the atmosphere if we burned all our fossil fuels? A: Professor James Renwick, school of geography, environment and earth sciences, Victoria University says: If we were to use up all of our planet's fossil-fuel resources, we'd increase the global average temperature by about 8 degrees Celsius globally by 2300, Canadian scientists report in Nature...

The Alberta wildfire is dumping mercury into the atmosphere
2016-05-19 19:11:00| Climate Ark Climate Change & Global Warming Newsfeed
Grist: Alberta`s massive wildfire is sending more than just smoke into the air. The Fort McMurray fire, which merged with another smaller wildfire last week, has displaced residents and cleared nearly everything in its path, including swaths of the region`s dense boreal forests. The combined blaze has already released the equivalent of 5 percent of Canadas annual carbon dioxide emissions and is expected to continue to burn for the next few months. The fires have also filled Fort McMurray`s air with...
