The world is sailing into some killer storms and its leaders have done almost nothing to protect its boat. That’s the view of UW Professor Steve Gardiner, who likens climate change to a perfect storm — a convergence of three difficult problems that so far we’ve found ourselves unable to face, much less solve.(more…)
*Berkeley Lab scientists help verify science behind geologic carbon sequestration*
A demonstration project on the southeastern tip of Australia has helped to verify that depleted natural gas reservoirs can be repurposed for geologic carbon sequestration, which is a climate change mitigation strategy that involves pumping CO2 deep underground for permanent storage.
The project, which includes scientists from Lawrence Berkeley National Laboratory (Berkeley Lab), also demonstrated that depleted gas fields have enough CO2 storage capacity to make a significant contribution to reducing global emissions. (more…)
PASADENA, Calif. – By 2100, global climate change will modify plant communities covering almost half of Earth’s land surface and will drive the conversion of nearly 40 percent of land-based ecosystems from one major ecological community type – such as forest, grassland or tundra – toward another, according to a new NASA and university computer modeling study.
Researchers from NASA’s Jet Propulsion Laboratory and the California Institute of Technology in Pasadena, Calif., investigated how Earth’s plant life is likely to react over the next three centuries as Earth’s climate changes in response to rising levels of human-produced greenhouse gases. Study results are published in the journal Climatic Change.(more…)
J. Timmons Roberts, professor of sociology and director of the Center for Environmental Studies, led a group of Brown researchers and students to the United Nations climate change negotiations in Durban, South Africa. On his return, Roberts spoke with Richard Lewis, reflecting on the Durban meetings, the status of research, and the challenges of activism on issues of climate change.
Timmons Roberts, professor and director of the Center for Environmental Studies, has just returned from attending climate talks in Durban, South Africa. Roberts and a delegation from Brown — faculty, postdoctoral researchers, graduate and undergraduate students — witnessed the negotiations up close as observers to ministerial speeches and negotiations. The talks ended with an agreement to extend the greenhouse gas emissions targets set under the Kyoto Protocol and a pledge to work on a replacement treaty incorporating the United States, China, and India.
Roberts spoke with Richard Lewis on the importance of the talks, the need for industrialized countries to compensate developing countries for damages from climate change, and the unique opportunity for people from Brown’s environmental program to attend the talks. (more…)
SAN FRANCISCO – An unusually hot melting season in 2010 accelerated ice loss in southern Greenland by 100 billion tons – and large portions of the island’s bedrock rose an additional quarter of an inch in response.
That’s the finding from a network of nearly 50 GPS stations planted along the Greenland coast to measure the bedrock’s natural response to the ever-diminishing weight of ice above it.
Every year as the Greenland Ice Sheet melts, the rocky coast rises, explained Michael Bevis, Ohio Eminent Scholar in Geodynamics and professor in the School of Earth Sciences at Ohio State University. Some GPS stations around Greenland routinely detect uplift of 15 mm (0.59 inches) or more, year after year. But a temperature spike in 2010 lifted the bedrock a detectably higher amount over a short five-month period – as high as 20 mm (0.79 inches) in some locations. (more…)
*University of Minnesota professor is part of international team that predicts the volatile region’s water may once again vanish*
MINNEAPOLIS / ST. PAUL — An international team of scientists drilling deep under the bed of the Dead Sea has found evidence that the sea may have dried up during a past warm period similar to predicted scenarios for climate change in coming decades. Emi Ito, professor of earth sciences in the University of Minnesota’s College of Science and Engineering, is a research team member. (more…)
*Blue Gene/Q tackles major challenges of the day, delivers up to 100 petaflops at peak performance*
ARMONK, NY – 15 Nov 2011: IBM todayannounced its next generation supercomputing project, Blue Gene/Q, will provide an ultra-scale technical computing platform to solve the most challenging problems facing engineers and scientists at faster, more energy efficient, and more reliable rates than ever before. Blue Gene/Q is expected to predict the path of hurricanes, analyze the ocean floor to discover oil, simulate nuclear weapons performance and decode gene sequences.
When it is fully deployed in 2012 at Lawrence Livermore National Laboratory (LLNL), the system, named “Sequoia”, is expected to achieve 20 petaflops at peak performance, marking it as one of the fastest supercomputers in the world. The capabilities this system represents will help ensure United States leadership in high performance computing (HPC) and the science it makes possible. Moreover, Blue Gene/Q is expected to become the world’s most power-efficient computer, churning out 2 gigaflops per watt. (more…)
