Fracking for oil and natural gas is transforming America's energy economy. The resulting low-priced natural gas has undercut nuclear, coal, and renewable power. This boom is spreading globally, with the U.S. poised to become the world's largest petroleum producer, potentially undermining OPEC and altering geopolitical power.

Russell Gold's book, *The Boom: How Fracking Ignited the American Energy Revolution and Changed the World*, details how Texas and Oklahoma innovators perfected hydraulic fracturing. In this video, Gold, a Wall Street Journal reporter, provides a brief history of fracking's origins and its industry evolution. Published in 2015, his book is available for order.

JPL scientist Josh Willis, from NASA's Ask A Climate Scientist campaign, asserts that global warming is not pausing, despite some decades showing slower surface temperature increases.

Willis points to increased ocean heat trapping and continuously rising sea levels as clear evidence. See [global temperature trends](http://climate.nasa.gov/key_indicators#globalTemp) and [sea level records](http://climate.nasa.gov/key_indicators#seaLevel).

While natural fluctuations occur, human-caused climate change is undeniably progressing. Explore more NASA climate science answers [here](http://bit.ly/1b7rSdL).
