Ocean acidification dissolving shell of planktonic Southern Ocean snails

November 25th, 2012 by British Antarctic Survey

A paper “Extensive dissolution of live pteropods in the Southern Ocean” published online in Nature Geoscience suggests that the effects of ocean acidification on marine ecosystems are beginning to emerge. Dr Geraint Tarling, of the British Antarctic Survey, and colleagues, examined shells collected from a pteropod, Limacina helicina antarctica, (a planktonic marine snail) in the surface […]

Greenhouse gases in atmosphere continue to increase in 2011

November 20th, 2012 by World Meteorological Organization

The World Meteorological Organization reports that greenhouse gases in the atmosphere reached a new record high in 2011. Between 1990 and 2011 there was a 30% increase in radiative forcing – the warming effect on our climate – because of carbon dioxide (CO2) and other heat-trapping long-lived gases. According to WMO’s 2011 Greenhouse Gas Bulletin, […]

Human carbon emissions may turn ocean acidic at faster rate than during four major extinctions

March 1st, 2012 by The Earth Institute at Columbia University

The world’s oceans may be turning acidic faster today from human carbon emissions than they did during four major extinctions in the last 300 million years, when natural pulses of carbon sent global temperatures soaring, says a new study, The Geological Record of Ocean Acidification, published in Science. The study is the first of its kind […]

US NOAA’s National Climatic Data Center finds 2010 tied with 2005 as warmest year for global surface temperatures since records began

January 13th, 2011 by United States National Oceanic and Atmospheric Administration

Preliminary analysis of data by scientists from the National Oceanic and Atmospheric Administration finds that 2010 tied with 2005 as the warmest year of the global surface temperature record since records began in 1880. NOAA’s National Climatic Data Center has distilled the following information for 2010 from the data. Combined global land and ocean annual […]
