"This week, Beyond the Data looks at one of the more well-grounded “rules of thumb” for understanding climate change.
" ... on average, cooler places and cooler times are warming more quickly than warmer places and times.
" ... the arctic is the fastest-warming large region on the planet.
The Arctic is warming at more than twice the rate of the rest of the world."
" ... there is evidence that high-elevation places are warming more, on average, than lower elevation places."
"In most of the mid-latitudes, where most Americans live, and where we have something resembling four seasons each year, the cold season is warming the most rapidly of all."
"This shows up clearly in the US temperature record, particularly during the last quarter-century, when the excursions from the long-term average are much larger during the winter season than the summer."
"Since the turn of the 20th century, the nation’s average winter (December through February) temperature has increased by almost twice the rate of the summer (June through August) temperature, at 2.0°F per century versus 1.1°F per century, respectively."
" ... the cooler time of the day shows more effects of warming than the warmer time."
"So, there you have it.
The cool places and the cool seasons and even the cooler times of day are warming more than the warmer places, seasons and times."
"It’s a rule of thumb, which means that there are plenty of exceptions, but more often than not, it’s true."
