The study, published in the journal Nature, relies on data on past ice levels of the Totten Glacier in East Antarctica to evaluate the rate of melting. Without intense efforts to stem man-made global warming, the glacier’s melting process could cross the point of no return within the next 100 years, according to report. The result would add more than 6.6 feet (2 meters) of sea level rise over the coming several centuries, in addition to several feet of rise from other sources.
“The evidence coming together is painting a picture of East Antarctica being much more vulnerable to a warming environment than we thought,” said study author Martin Siegert, an Imperial College London researcher, in a press release. “This is something we should worry about.”

Friends have been asking me to write something on space exploration and my campaign policy on it, so here it is just out on TechCrunch:
When people think about rocket ships and space exploration, they often imagine traveling across the Milky Way, landing on mysterious planets and even meeting alien life forms.
In reality, humans’ drive to get off Planet Earth has led to tremendous technological advances in our mundane daily lives — ones we use right here at home on terra firma.
I recently walked through Boston’s Logan International Airport; a NASA display reminded me that GPS navigation, anti-icing systems, memory foam and LED lights were all originally created for space travel. Other inventions NASA science has created include the pacemaker, scratch-resistant lenses and the solar panel.
The future of movies and manufacturing may be in 3D, but electronics and photonics are going 2-D; specifically, two-dimensional semiconducting materials.
One of the latest advancements in these fields centers on molybdenum disulfide (MoS2), a two-dimensional semiconductor that, while commonly used in lubricants and steel alloys, is still being explored in optoelectronics.
Recently, engineers placed a single layer of MoS2 molecules on top of a photonic structure called an optical nanocavity made of aluminum oxide and aluminum. (A nanocavity is an arrangement of mirrors that allows beams of light to circulate in closed paths. These cavities help us build things like lasers and optical fibers used for communications.)
China’s state-owned Shenhua Group Corp. has just signed a memorandum of understanding with Santa Monica based SolarReserve, partnering to bring 1,000 MW of clean energy into China.
Green is going global. More and more countries are getting in on the green energy bandwagon, shifting their energy dependencies from fossil fuel burning to renewable energy. And the biggest recipient of this? Solar.
Countries are increasingly depending on the Sun to provide for their energy needs. And this means the building of bigger and better solar farms.
These automaker knuckleheads were planning to try and hide self driving cars into the 2030’s:
Head of GM’s foresight and trends unit says timetable for autonomous vehicles likely moved from 2035 to 2020, if not sooner.
A General Motors Co. executive credited Silicon Valley companies, including Alphabet Inc.’s Google car division and Tesla Motors Inc., for accelerating the development of autonomous vehicle technology and shortening the timetable for when safer self-driving cars hit the road.
Richard Holman, a 30-year automotive veteran running GM’s foresight and trends unit, said Tuesday that three years ago most industry participants would have estimated 2035 as a reasonable timetable for self-driving cars. Speaking to a conference in suburban Detroit, Mr. Holman said now most people see that technology being deployed by 2020, if not sooner.
Recognizing the importance of biofuels to energy and climate security, the U.S. Department of Energy has announced up to $90 million in project funding focused on designing, constructing and operating integrated biorefinery facilities. The production of biofuels from sustainable, non-food, domestic biomass resources is an important strategy to meet the Administration’s goals to reduce carbon emissions and our dependence on imported oil.
Project Development for Pilot and Demonstration Scale Manufacturing of Biofuels, Bioproducts, and Biopower is a funding opportunity meant to assist in the construction of bioenergy infrastructure to integrate cutting-edge pretreatment, process, and convergence technologies. Biorefineries are modeled after petroleum refineries, but use domestic biomass sources instead of crude oil, or other fossil fuels to produce biofuels, bioproducts, and biopower. They convert biomass feedstocks—the plant and algal materials used to derive fuels like ethanol, butanol, biodiesel and other hydrocarbon fuels—to another form of fuel or energy product. This funding will support efforts to improve and demonstrate processes that break down complex biomass feedstocks and convert them to gasoline, diesel and jet fuel, as well as plastics and chemicals.
“The domestic bio-industry could play an important part in the growing clean energy economy and in reducing American dependence on imported oil,” said Lynn Orr, DOE’s under secretary for science and energy. “This funding opportunity will support companies that are working to advance current technologies and help them overcome existing challenges in bioenergy so the industry can meet its full potential.”
