New research from NASA indicates an unstoppable chain reaction of Antarctic ice melt in the Amundsen sea

NASA Research Indicates Slow, Irreversible West Antarctic Ice Melt

Bad news for Antarctic ice, but not particularly surprising to scientists Several news headlines this week have heralded the “unstoppable” decline of a major portion of the West Antarctica ice sheet in the Amundsen Sea, eventually disappearing in as little as two centuries. Projections for the complete collapse of the West Antarctic ice sheet range from two hundred to nearly nine hundred years, but what…

growing concern from scientists studying the Greenland and Antarctica ice sheets over the potential for sea level rise

Video Friday: Growing Concern Over Sea Level Rise

From the Yale Climate Forum. Scientists studying the Greenland and Antarctic ice sheets express growing concern over the fragility and vulnerability of the world’s ice sheets and the potential impact on sea level rise. Researchers in Antarctica are using sophisticated equipment to drill down 500 meters below the ice shelf to measure ice loss, temperature, salinity and speed of melt….

14 Steps to Reduce Black Carbon and Stabilize the Cryosphere

Climate change is causing unprecedented changes in the Earth’s regions of snow and ice, portents of profound, dramatic change for ecosystems and societies around the world, according to a joint report released by The World Bank and The International Cryosphere Climate Initiative (ICCI) November 4. The Earth’s cryosphere is warming more rapidly than anticipated – “at a pace unprecedentd in…

Above Average Temperatures for November Keep U.S. on Track for Record Hot Year

On Monday, scientists from the National Oceanic and Atmospheric Administration (NOAA) said that for the 333rd consecutive month November 2012 brought higher than average global temperatures. In fact, the last time November temperatures dropped below the 20th century average was in 1976. Last month global average temperature over land and oceans was 56.41°F, or the 5th highest recorded average land/sea…

Video Friday: Temperature Leads CO2? The 800-Year Lag

Potholer54 (a.k.a Peter Hadfield) tackles a common myth about climate change often called the “800-year lag.”  Antarctic ice core data shows CO2 lagging temperature during periods of deglaciation; this has been well understood for decades. Despite this, many climate change “skeptics” ignore the full picture of numerous studies over the years and assert these data of ancient deglaciation “proves” that CO2…
