USGS Suggests Connection Between Seismic Activity and Fracking 145

First time accepted submitter samazon writes "According to a recently proposed abstract by the United States Geological Survey, hydraulic fracturing, or more specifically the disposal of fracking wastewater, may be directly correlated to the increase in seismic activity in the midwest. Results of the paper will be presented on April 18th, but the language of the abstract seems to imply that there is a connection. After years of controversy regarding hydrofracking including ground water contamination and disclosure of chemical solutions, the results of the study, if conclusive, could influence the cost of natural gas due to increased regulations on wastewater disposal." The actual language of the abstract leaves a fair amount of wiggle room: "While the seismicity rate changes described here are almost certainly manmade, it remains to be determined how they are related to either changes in extraction methodologies or the rate of oil and gas production."

1981 Paper's Predictions for Global Temperatures Spot-On 371

Layzej writes "The Register reports on a paper published in Science in 1981 projecting global mean temperatures up to the year 2100. 'When the 1981 paper was written, temperatures in the northern hemispheres were declining, and global mean temperatures were below their 1940 levels. Despite those facts, the paper's authors confidently predicted a rise in temperature due to increasing CO2 emissions.' The prediction turns out to be remarkably accurate — even a bit optimistic. The article concludes that the 1981 paper is 'a nice example of a statement based on theory that could be falsified and up to now has withstood the test.'"
