Steven ChuEnergy Secretary Steven Chu is claiming that scientific evidence for climate change is as convincing as ever a comment that arrives just as controversies surrounding the renewable energy industry and new Environmental Protection Agency (EPA) rules face staunch opposition from Republicans and industry groups.

space shuttleThe theory of a human cause for global warming received another serious setback as dozens of former NASA scientists and astronauts called upon the American space agency to rely on actual evidence — rather than computer models — in the study of the controversial theory.

President Obama drew praise from the energy industry on Friday after issuing an executive order to amend federal oversight procedures of hydraulic fracturing — commonly known as "fracking" — which injects water, sand, and chemicals deep underground to release vast quantities of fuel. The order creates an "interagency working group" that directs 12 federal agencies to collaborate in bolstering "safe and responsible unconventional domestic natural gas development."

A new scientific study of the Himalayan glaciers is raising fresh doubts about the troubled theory of manmade climate change, and could renew interest in a debacle that shook the Intergovernmental Panel on Climate Change (IPCC) several years ago.

The Environmental Protection Agency (EPA) on Wednesday unveiled its first-ever regulations to curb air pollution from hydraulic fracturing, the drilling process commonly known as "fracking" — or in the industry's parlance, "fracing." By 2015, natural-gas and oil drillers will be forced to invest in new equipment that curtails smog-forming emissions from fracing wells.
