It depends on who you are and where you live. Humans thrive in Kuwait City, where average highs top 110° for several months a year. But extended runs of hot days and warm nights do lead to spikes in mortality, and climatologists expect an increasing number of heat waves in years to come.

Unpredictable extremes of weather could be a huge problem. Simon N. Gosling, a geographer at the University of Nottingham in England, and Robert E. Davis of the University of Virginia agree that hotter weather on average isn't as dangerous as unexpected weather. A study published in the Proceedings of the National Academy of Sciences in April looked at how temperature fluctuations over a single summer affect mortality in vulnerable populations.

Hot enough to boil oceans and vaporize rock. The highest terrestrial temperatures occurred more than four billion years ago, when a Mars-size proto-planet smashed into the Earth. (The debris from this collision formed our moon.) Within a millennium, the surface air temperature had dropped from a high of about 3,700°F down to 3,000°. Then the planet went into a period of slower cooling that lasted a few tens of millions of years.

Later this year, Ford will roll out the Focus Electric, Detroit's first direct competitor to the Nissan Leaf. Like the Leaf, the Focus Electric is an all-electric five-door hatchback with a 600-plus-pound lithium-ion battery, a driving range of close to 100 miles on a charge, and a price tag north of $35,000. Unlike the Leaf, the Focus Electric is not a purpose-built EV; it looks almost identical to the gas-powered Focus, which is manufactured on the same Michigan assembly line.
