Acidity in atmosphere minimized to preindustrial levels

ScienceDaily: New research shows that human pollution of the atmosphere with acid is now almost back to the level that it was before the pollution started with industrialisation in the 1930s. The results come from studies of the Greenland ice sheet and are published in the scientific journal, Environmental Science and Technology. The Greenland ice sheet is a unique archive of the climate and atmospheric composition far back in time. The ice sheet is made up of snow that falls and never melts, but rather remains...

CO2 levels in atmosphere surpass limit. What now?
2016-06-15 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
Christian Science Monitor: A group of scientists who monitor Earths atmosphere using data from Hawaiis Mauna Loa Observatory announced yesterday that our climate has reached a milestone. The Earth's atmosphere now contains 400 parts per million (ppm) of carbon dioxide, a level of greenhouse gases considered a symbolic limit, the team of researchers wrote in a study published in the journal Nature Climate Change. And that level's not going to change anytime soon, they say. "Our forecast supports the suggestion that...

The atmosphere has hit a grim milestone
2016-06-14 15:06:44| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: 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 the longest global record of Co2 has been compiled. Our forecast supports the suggestion that the...
