Ecologist: The news is consistent with trends in fossil fuel consumption. But what comes as more of a surprise is the WMO's revelation that the current rate of ocean acidification, which greenhouse gases (GHGs) help to cause, appears unprecedented in at least the last 300 million years. "We know without any doubt that our climate is changing and our weather is becoming more extreme due to human activities such as the burning of fossil fuels", said the WMO's secretary-general, Michel Jarraud. "The Greenhouse...

Ozone layer shows signs of recovery after 1987 ban on damaging gases

Guardian: The ozone layer that shields life from the sun's cancer-causing ultraviolet rays is showing its first sign of thickening after years of dangerous depletion, a UN study said on Wednesday. Experts said it showed the success of a 1987 ban on manmade gases that damage the fragile high-altitude screen, an achievement that would help prevent millions of cases of skin cancer and other conditions. The ozone hole that appears annually over Antarctica has also stopped growing bigger every year, though...

UN: Greenhouse Gases Hit Record Levels Last Year
2014-09-09 10:31:00| Climate Ark Climate Change & Global Warming Newsfeed
Voice of America: The United Nations says surging carbon dioxide emissions sent greenhouse gases in the atmosphere to record levels last year. In its annual report on greenhouse gas concentrations released Tuesday, the World Meteorological Organization (WMO) said carbon dioxide levels between 2012 and 2013 marked the largest yearly increase since reliable global records began 30 years ago. A large percentage of carbon dioxide emissions are absorbed by the oceans. In a statement accompanying the report, WMO...

Rise in greenhouse gases spurs fears over climate
2014-09-08 23:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Washington Post: Levels of heat-trapping carbon dioxide in the atmosphere rose at a record-shattering pace last year, a new report shows, a surge that surprised scientists and spurred fears of an accelerated warming of the planet in decades to come. Concentrations of nearly all the major greenhouse gases reached historic highs in 2013, reflecting ever-rising emissions from automobiles and smokestacks but also, scientists believe, a diminishing ability of the worlds oceans and plant life to soak up the excess carbon...
