The last couple of years have certainly felt unusually hot in many parts of the U.S., but are they really all that unusual?
Many people wonder whether a warming climate is turning up the temperature or whether it's all just part of the normal variation in the weather. Among scientists, there's a growing view that these latest heat waves are indeed a result of climate change.

In July, the financial fortunes of the presidential candidates continued along their new trajectories, with Republican Mitt Romney's money-raising efforts outpacing President Obama once again.

Romney, the all-but-official Republican nominee, actually collected less in July than he had in June, but only slightly. His campaign announced Monday that its overall take for July was $101.3 million.
