Record High Temperatures Far Outpace Record Lows Across US

No surprise to me. When I look at the local weather report, I have noticed that most often (of course not always) the year of the previous high temperature is more recent than the year of the previous low temperature.

ScienceDaily (Nov. 13, 2009) — Spurred by a warming climate, daily record high temperatures occurred twice as often as record lows over the last decade across the continental United States, new research shows. The ratio of record highs to lows is likely to increase dramatically in coming decades if emissions of greenhouse gases continue to climb.

"Climate change is making itself felt in terms of day-to-day weather in the United States," says Gerald Meehl, the lead author and a senior scientist at the National Center for Atmospheric Research (NCAR). "The ways these records are being broken show how our climate is already shifting."
