It's been a record hot summer in many cities across the nation. Phoenix is no exception. This Sonoran Desert metropolis already records more days over 100 degrees than any other major U.S. city. Now, climate models predict Phoenix will soon get even hotter.
A hotter future may mean a more volatile environment — and along with it, natural disasters, greater pressure on infrastructure, and an increased physical toll on city residents.
Mitt Romney's new running mate has authored some provocative policy proposals to cut budget deficits and overhaul Social Security, Medicare and Medicaid. But Rep. Paul Ryan has also been an advocate for a different course for the central banking system of the United States, the Federal Reserve.

Wind turbines near Ellhoeft, in northern Germany, close to the Danish border. The challenge for Germany's new energy plan is how to transmit power generated in the north to the population centers in the south.
After Japan's Fukushima disaster last year, Germany announced a groundbreaking energy plan: It would phase out all of its domestic nuclear power in a decade and make a transition to safer, carbon neutral energy.
The goal is to have solar, wind and other renewables account for nearly 40 percent of the energy for Europe's largest economy in a decade, and 80 percent by 2050.
