Virginia Center for Coal and Energy Research helps implement global climate change initiative
...c sinks include oil and gas reservoirs, unmineable coal
seams, and deep saline aquifers. These structures have stored oil, natural gas, brine and CO2 over millions of years. Many power plants and other large sources of CO2 are located near potential geologic sinks. In many cases, injection of CO2 into a g...
Research finds lawn chemicals raise cancer risk in Scottish terriers
...e. "You might compare them to the canaries used in coal
mines a century ago," he said. "The difference is that we don't deliberately place our research animals in harm's way. We study animals that have already contracted diseases, bring them to the hospital and then try to find out what combination of gen...
For the sake of land and climate, coaxing soil to soak up carbon
