In energy policy, political polarization often gets in the way of commonsense solutions to problems.
General Electric recently announced a technological advance that would allow pipeline companies to use drone-mounted cameras to inspect their lines for corrosion and leaks. This is the kind of development that could, with the right regulatory support, make huge strides toward preventing costly and harmful spills and solving other important problems afflicting America’s aging pipeline infrastructure.

Washington, DC—New work from an international team including Carnegie’s Ken Caldeira demonstrates that the planet’s remaining fossil fuel resources would be sufficient to melt nearly all of Antarctica if burned, leading to a 50- or 60-meter (160- to 200-foot) rise in sea level. Because so many major cities are at or near sea level, this would put many highly populated areas where more than a billion people live under water, including New York City and Washington, DC. It is published in Science Advances.(more…)
Turning fossil fuel into energy is easy: You just burn it. And live with the carbon dioxide byproduct. What if we could reverse the process and turn water and carbon dioxide back into fuel?
A dream solution, but it may seem like trying to put the genie back in the bottle. (more…)
Richard Rood, is a professor of atmospheric, oceanic and space sciences at the University of Michigan. He loves discussing the intersections of weather and climate, and climate and society. One of his current projects involves studying trends in extreme heat events. Rood is a blogger at Weather Underground and teaches a class on climate change problem solving.(more…)
COLUMBIA, Mo. — While Americans prepare to cook millions of turkeys for Thanksgiving, a geothermal energy system developed by a University of Missouri engineer will be keeping live turkeys toasty during the chilly autumn weather. In a prototype facility, designed by a University of Missouri engineer, environmentally and economically friendly geothermal energy is keeping turkeys comfortable during both cold and hot weather. The system is designed to reduce utility costs while improving the air quality for the birds.
“This is our first prototype of a geothermal system in a commercial livestock operation,” said Yun-Sheng Xu, associate research professor in civil and environmental engineering. “Our first set of performance data suggests that farmers could cut their heating costs in half at current propane prices. Currently, two units are installed at the test farm. Other farmers could begin installing units on their turkey farms as soon as next year, for use by next winter.” (more…)
Berkeley Lab researchers devise a new method to estimate state’s greenhouse gas emissions.
Using a new method for estimating greenhouse gases that combines atmospheric measurements with model predictions, Lawrence Berkeley National Laboratory (Berkeley Lab) researchers have found that the level of nitrous oxide, a potent greenhouse gas, in California may be 2.5 to 3 times greater than the current inventory.
At that level, total N2O emissions—which are believed to come primarily from nitrogen fertilizers used in agricultural production—would account for about 8 percent of California’s total greenhouse gas emissions. The findings were recently published in a paper titled “Seasonal variations in N2O emissions from central California” in Geophysical Research Letters. Earlier this year, using the same methodology, the researchers found that levels of methane, another potent greenhouse gas, in California may be up to 1.8 times greater than previous estimates.

A new study has found that climate-prediction models are good at predicting long-term climate patterns on a global scale but lose their edge when applied to time frames shorter than three decades and on sub-continental scales.
Climate-prediction models show skills in forecasting climate trends over time spans of greater than 30 years and at the geographical scale of continents, but they deteriorate when applied to shorter time frames and smaller geographical regions, a new study has found.
Published in the Journal of Geophysical Research-Atmospheres, the study is one of the first to systematically address a longstanding, fundamental question asked not only by climate scientists and weather forecasters, but the public as well: How good are Earth system models at predicting the surface air temperature trend at different geographical and time scales?

Scientists are setting sail on August 25 to study ocean acidification in the Arctic and what this means for the future survival of marine and terrestrial organisms.
The Arctic Ocean is one of the most vulnerable places on the planet for acidification, yet it is the least-explored ocean. Acidification can disturb the balance of marine life in the world’s oceans, and consequently affect humans and animals that rely on those food resources.
Ocean acidification is particularly harmful to organisms such as corals, oysters, crabs, shrimp and plankton, as well as those up and down the food chain. Higher acidity decreases an organism’s calcification rate, meaning they lose their ability to build shells or skeletons. (more…)
