EarthTalk: Antarctic Ice Melt

EarthTalk® is a weekly environmental column made available to our readers from the editors of E/The Environmental Magazine Dear EarthTalk: To what extent is Antarctica really melting and what impact might it have on coastlines around the world? – Andrea Hutchinson, Cary, NC The Antarctic continent, roughly the size of the United States and Mexico combined, is composed of rock covered…

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…

Accelerating ice melt from the Greenland and Antarctic ice sheets will significantly impact sea level rise in the coming decades

Melting Ice Sheets the Largest Contributor to Sea Level Rise

A new study to be published this month in the journal Geophysical Research Letters has found that the Greenland and Antarctic ice sheets are losing mass at an accelerating rate. The rapidly accelerating ice melt from the ice sheets is happening much sooner the models have predicted. According to the research, the ice sheets are now overtaking the ice loss…

New research warns of longterm effects of climate change even after emissions stop

CO2 Inertia Will Trigger Climate Change for Next Millennium, Study Says

According to a research study just published in the journal Nature Geoscience, climate change will persist, and in some parts of the world intensify, from the increased levels of atmospheric CO2 long after humans stop burning fossil fuels – for a millennium or more, the report says. Longterm climate change In even a best case, real-world scenario where anthropogenic carbon emissions…

Book Review: A World Without Ice by Dr. Henry Pollack

“Ice asks no questions, presents no arguments, reads no newspapers, listens to no debates. It is not burdened by ideology and carries no political baggage as it changes from solid to liquid. It just melts.” —- Even in its absence, ice rules land and sea. The unmistakable signs of its power and influence are seen in the planet’s landscape, and…
