New Study Shows Antarctic Melting Approaching ‘Unstoppable’ Tipping Point

‘What we call the eternal ice of Antarctica unfortunately turns out not to be eternal at all,’ says lead author of new study A new study published Monday warns that “unstoppable” melting in West Antarctica could make a three-meter increase in sea level “unavoidable.” According to researchers at Germany’s Potsdam Institute for Climate Impact Research, the vulnerable Amundsen Sea sector …

Andrea Germanos – NASA: World ‘Locked Into’ at Least 3 Feet of Sea Level Rise

New research underway indicates that at least three feet of global sea level rise is near certain, NASA scientists warned Wednesday. That’s the higher range of the 1 to 3 feet level of rise the UN Intergovernmental Panel on Climate Change (IPCC) gave in its 2013 assessment. Sea levels have already risen 3 inches on average since 1992, with some areas …

Washington, DC sinking fast, adding to threat of sea-level rise

New research confirms that the land under the Chesapeake Bay is sinking rapidly and projects that Washington, D.C., could drop by six or more inches in the next century–adding to the problems of sea-level rise. This falling land will exacerbate the flooding that the nation’s capital faces from rising ocean waters due to a warming climate and melting ice sheets–accelerating …

Leading climate scientist: Future is bleaker than we thought

Highly speculative. Full of conjecture. Based on flimsy evidence. Not supported by mainstream science. Not peer reviewed. Not suitable for basing policy on. It sounds like climate scientists are talking about the claims of climate deniers. But this time they are talking about a 23 July discussion paper by James Hansen, the most famous and respected climate scientist on the planet. …

World’s Oceans Could Rise Higher, Sooner, Faster Than Most Thought Possible – Jon Queally

If a new scientific paper is proven accurate, the international target of limiting global temperatures to a 2°C rise this century will not be nearly enough to prevent catastrophic melting of ice sheets that would raise sea levels much higher and much faster than previously thought possible. “Parts of [our coastal cities] would still be sticking above the water, but …

Strong geothermal heating measured beneath West Antarctic Ice Sheet – SPACE DAILY

A surprisingly high amount of geothermal heating has been measured underneath the West Antarctic Ice Sheet by researchers at the University of California, Santa Cruz. Using a lengthy probe, researchers measured the flow of heat in the sediments below the ice sheet. A significant flow of heat is traveling upward form the geothermal sources toward the base of the ice. …

Global sea levels have risen six meters or more with just slight global warming

A new review analyzing three decades of research on the historic effects of melting polar ice sheets found that global sea levels have risen at least six meters, or about 20 feet, above present levels on multiple occasions over the past three million years. What is most concerning, scientists say, is that amount of melting was caused by an increase …

Ice sheet collapse triggered ancient sea level peak

An international team of scientists has found a dramatic ice sheet collapse at the end of the ice age before last caused widespread climate changes and led to a peak in the sea level well above its present height. The team found the events 135,000 years ago caused the planet to warm in a different way to the end of …

The Gary Null Show – 05.04.15

Today, vitamin B12 deficiency in children, a treatable cause of neurodevelopment delay. Just an hour day of TV watching creates unhealthy weight gain in children. Fish liver oil, when younger, can produce a healthier heart when you’re older. Replacing one sugary drink per day with water cuts diabetes risk. From the environmental segment, faster melting of the antarctic ice sheet. Plus, government now plans on targeting pregnant women for vaccinations. And more.

“Ground Zero” Moves to Antarctica

Peru’s Quelccaya Ice Cap (alt. 17,950 ft.), the world’s largest tropical ice cap, will likely lose another 400-600 feet of ice before the final presidential nominating debates in March/April 2016. All of which brings to mind, wouldn’t it be interesting to ask the prospective presidential nominees this question: What are the implications of Antarctica suddenly becoming “ground zero” for global …
