The National Weather Service replaced the temperature sensor at Reagan National Airport this week because it has been running too hot by approximately 2 deg. F since January of 2014. Virgina state climatologist explains by comparing temperatures at Dulles (IAD) with Reagan National (DCA): "Of course DCA is going to be intrinsically warmer than IAD. It’s several hundred feet lower in elevation and its being additionally heated by the bricks, buildings, and the pavement of urban Washington, as well as the waste heat from all your money changing hands. What is interesting is that the departures from normal, or “anomalies,” at DCA were all running hot compared to the departures from normal at IAD". The Capital Weather Gang offers additional temperature analyses of the two airports and questioned 3 years ago if Reagan National should remain DC's official weather station. Meanwhile, recent records, like this past May which was thought to be the hottest May on record at DCA are now called into question.

Pronbably to no one's surprise, Southern California leads the nation in the number of pleasant days per year (mean temperature between 55° F and 75° F, no precipitation). How does your city stack up?

Quantum gas goes below absolute zero. "It may sound less likely than hell freezing over, but physicists have created an atomic gas with a sub-absolute-zero temperature for the first time. Their technique opens the door to generating negative-Kelvin materials and new quantum devices, and it could even help to solve a cosmological mystery."
Ninety years ago today, the all-time weather temperature record (58° C, 136.4° F) was recorded at Al Azizia, Libya. Today, that record has been officially thrown out following research by extreme weather specialist, Christopher Burt. The video of how it all un-happened. [more inside]
Looking back at the past week, as thunderstorms finally rolled into the Midwest Saturday evening, it seems that the past week's extreme heat (previously) has broken more than 3,500 temperature records in the U.S. [more inside]
Minus 40 degrees is the same temperature in both Celsius and Fahrenheit. It is also the temperature where skin freezes, and the point where water is completely frozen (and mercury too). Strangely, it's also the average temperature of the record lows for all 50 United States, though normal in Alaska.
Climate Variability and Climate Change: The New Climate Dice An excerpt from what should be a very incendiary academic paper by Hansen, J, et al: Thus there is no need to equivocate about the summer heat waves in Texas in 2011 and Moscow in 2010, which exceeded 3σ – it is nearly certain that they would not have occurred in the absence of global warming. If global warming is not slowed from its current pace, by midcentury 3σ events will be the new norm and 5σ events will be common.
Climate Wizard enables you to access leading climate change information and visualize the impacts anywhere on Earth. This web-based program allows you to choose a state or country and both assess how climate has changed over time and project what future changes are predicted to occur in a given area.
