Atmospheric rivers are long, narrow conveyor belts of rainstorms that stream in from the Pacific Ocean. Meteorologists have been able to predict the storms five days in advance, thanks to a new network of weather sensors recently installed in California.

Natural gas, which is often perceived as a clean alternative to coal and oil, can be advantageous since it produces fewer greenhouse-gas emissions than other fossil fuels. This was one of the reasons why there was a large scale shift to natural gas in the 1990s. However, to release the gas, engineers must split rock by injecting a high-pressured fluid, a process which is called hydraulic fracking.
