Antarctic Permafrost in the McMurdo Dry ValleysJoseph Levy was preparing for a season of scientific research in Antarctica last week when he got the call: Stand down. Dr. Levy, a research associate at UT Austin’s Institute for Geophysics, is studying the climate history of the dry valleys of Antarctica by analyzing buried ice sheets that have been frozen since the last ice age and are beginning to thaw.

SunlightVariations in the rate of global warming since the 1970s were not caused by atmospheric changes that affect how much solar radiation reaches the Earth’s surface, a new study says.Over the past century, rising greenhouse gas levels have caused global average temperatures to increase, climate scientists Kaicun Wang and Robert Dickinson write in the Proceedings of the National Academy of Sciences this week.

Eagle Ford Shale MapSo much oil and water is being removed from South Texas’ Eagle Ford Shale that the activity has probably led to a recent wave of small earthquakes, according to a study that appears in the online edition of the journal Earth and Planetary Science Letters. The peer-reviewed study’s authors suggest that taking oil and water out of the ground allows surrounding rock and sand to settle, triggering small tremors that are typically too weak to be noticed on the surface.

Europa from Galileo Spacecraft

For the first time scientists have done a complete study of a possible Europa lander mission. The work will be reported in the journal Astrobiology. I had the opportunity to speak with Don Blankenship, a University of Texas geophysicist who is obsessed with Europa as much as I am, and perhaps more, about the clipper and lander proposals. He had a hand in authoring both of them.

Pioneer Natural Resources, one of the country’s largest independent oil and gas firms, is estimating the recoverable oil in a single field in West Texas’ Permian Basin at 50 billion barrels of oil and gas. At almost twice the estimated reserves in the Eagle Ford, that would make the field, named the Spraberry/Wolfcamp, the largest in the country and the second-largest in the world behind the Ghawar in Saudi Arabia.

Oil was first discovered in what was then known as the Spraberry in the 1940s but had always produced at “relatively low levels,” said Scott Hamlin, a researcher with the Bureau of Economic Geology at the University of Texas. “That’s changed in the last three years,” he said. “With the development of increasingly efficient techniques, they were able to produce rocks that were previously not producible, like the Eagle Ford.”

Antarctica’s Dry Valleys are home to the oldest ice on Earth. The first signs of the massive thaw disturbing the Arctic’s frozen ground have now appeared in one of these valleys, melting a glacier buried since the last Ice Age.

Last night, I watched the documentary “Switch,” narrated by Scott Tinker, a University of Texas professor and head of the Bureau of Economic Geology. Unlike “Gasland Part II,” the sensationalist all-fossil-fuels-are-bad screed that you’re likely to hear more about this summer, “Switch” offers a scientific look at how we use energy and how difficult it’s going to be to move away from fossil fuel. It also drives home the point that weaning ourselves from oil and coal in the U.S. is essential.

While coal is cheap and abundant, it’s dirty, and “clean coal” technology simply isn’t economically viable. “We probably could make coal clean,” Tinker says, “but we probably can’t afford to.”

A team of University of Texas researchers recently discovered a swamplike system of water under an Antarctic glacier the size of New Mexico — a finding that might hold the key to how quickly the polar ice will melt and the seas will rise. From a nondescript office at the J.J. Pickle Research Campus, sweltering in the midsummer heat like the rest of Central Texas, this research team has become renowned for its study of some of the coldest places on Earth — not to mention Jupiter’s icy moon, Europa.

Ancient volcanoes discovered deep in the ocean off Antarctica may explain a climate mystery critical to predicting Earth’s fate as humans pump more carbon dioxide into the atmosphere. University of Texas geologists dredging thousands of feet below the surface of the central Scotia Sea off the southeastern tip of South America hauled up volcanic rock after their sonar mapping showed formations that looked uncannily like a sunken island chain.

A road crew has discovered a large cave just a few feet below the surface along Highway 620, just west of Round Rock, Texas. Jack Sharp responds to a proposal that the highway department fill in the cave.
