Climate scientists normally are wary of associating daily weather events to longer term climate change, but new research does just that by showing that daily record high temperatures across the continental U.S. occurred twice as often as record lows over the last decade.

"Climate change is making itself felt in terms of day-to-day weather," Gerald Meehl, a researcher at the National Center for Atmospheric Research, said in a statement announcing the research. "The ways these records are being broken show how our climate is already shifting."

"One of the messages of this study is, you still get cold days," he said. "Winter still comes. Even in a much warmer climate, we're setting record low minimum temperatures on a few days each year. But the odds are shifting so there's a much better chance of daily record highs instead of lows."
