BBC News: CO2 climate sensitivity ‘overestimated’ Of all that is very clearly known about global climate change, the one connection that is not well understood is the quantity of climate forcing that results from each unit of CO2. That is, exactly how much additional heat can the atmosphere store for each each ton of CO2 that is added to it? One new study proposes that the existing model might be too pessimistic, basing that on the authors' theory that the last ice age wasn't as cold as has been believed. Their theorized rate of increase is still globally catastrophic, but comparatively speaking, it would be good news. The team's paper is published in Science magazine.
Wikipedia: Franksgiving In 1939, President Roosevelt made the annual declaration of a day of Thanksgiving—as had been done such President Washington—but selected the third Thursday in November, rather than the traditional last Thursday. That was at the request of retailers, who didn't want to violate the taboo of starting Christmas sales before Thanksgiving, but were worried that the fourth Thursday would fall too late in the year—November 30—to give them enough sales time. The moved date split the country, both along partisan lines and along state lines. Many states declared Thanksgiving holidays on the third Thursday, some on the fourth. This was repeated in 1940 and 1941, but it was settled by Congress, who officially designed the annual holiday as being the fourth Thursday, as of 1942.
American Radio Relay League: US Amateurs Now 700,000 Strong! There are more ham radio operators in the U.S. than ever before. Over 700,000 now. When I got licensed, in the early nineties, there were just under 500,000 licensed operators. I was one of the first people to get a codeless license, meaning that I didn't need to learn CW (aka Morse code); if that new class of license hadn't been established, I couldn't have passed the test. These days, I don't think CW is required for any of the three license classes—Technician, General, and Amateur Extra—which has surely helped this surge in licensing. (Fun fact: Long-time ARRL president Harry Dannals, aka W2HD, is a Charlottesville resident.)
