Local Warming

It's uncharacteristically warm and wet here in Southern New Mexico for the New Year's dawning. Surface temperatures are in the 50's (F) and the mountains just East of us (2700 meters) are still devoid of snow despite a rainy week. Meanwhile, Arctic and Antarctic Sea Ice are both at record lows for the date, and sea surface temperatures are above normal in both North and South. Meanwhile, former MIT prof, and possibly senile* nutjob Richard Lindzen thinks what we need is a ninety percent cut in Climate Science. Because what you won't admit wont hurt you, right? * - That may be unfair. Lindzen seems to have been pretty nutty for a long time.

Climate Change in History and Prehistory

Catastrophic climate change is hardly something new for the human race. The list of climate catastrophes that did in civilizations, cultures, and, very nearly, the whole human race is long but also rather poorly known and understood. Modern humans appeared in a particularly catastrophic geological time, the Pleistocene, in which giant ice sheets repeatedly covered big chunks of land and drove us from much of Europe (or exterminated those unlucky enough to be caught). The genetic evidence makes it clear that our population went through repeated bottlenecks when our numbers were reduced to a few thousands. The advent of agriculture and food storage, in the form of crops and herds, allowed our numbers to multiply rapidly, and may have made us less vulnerable to certain vagaries of weather but even more vulnerable to longer term climate shifts. Many a cultural or civilizational collapse can be traced to a widespread drought, including the collapse of the First Kingdom in Egypt and th...

RIP Vera Rubin

A key player in the discovery of dark matter, pioneer woman in astronomy. From the NYT: Vera Rubin, who transformed modern physics and astronomy with her observations showing that galaxies and stars are immersed in the gravitational grip of vast clouds of dark matter, died on Sunday in Princeton, N.J. She was 88. Her death was announced by the Carnegie Institution of Washington, where she had been a longtime staff astronomer. Dr. Rubin, cheerful and plain-spoken, had a lifelong love of the stars, championed women in science and was blunt about the limits of humankind’s vaunted knowledge of nature.

Merry Christmas to All and to All a Goodnight

And similar greeting to all who celebrate slightly different observances of the Winter solstice.

Smokin'

It's toasty down in Santa's workshop. Although subzero C, temperatures are about 20 C (36 F) warmer than normal, and scheduled to get warmer, or so claims this Tech Times story by Kalyan Kumar: Temperatures in the Arctic are predicted to rise nearly 50 degrees above normal from Thursday under the spell of a pre-Christmas heat wave. It means the frozen tundra is racing close to a melting point. The surging warmth in the past two months has already left scientists jittery, as escalating temperatures are feared to hit ice formation or coverage next summer and bring it down to record low levels. More warming trends are hitting the region as a result of climate change effects. Walt Meier, a NASA scientist at the Goddard Space Flight Center, said the current warmth is an offshoot of fluctuations in the jet stream that is passing frigid air to North America and parts of the Arctic. - See more at: http://www.techtimes.com/articles/189862/20161223/arctic-forecast-to-warm-by-as-much...

Yurts

Things I did and didn't want to know about them. One was the Inner Asian nomad's universal type of dwelling, a tent which in English is called yurt (from Russian yurta, a borrowing from Turkic, where, however; this term means home territory; specific variants ants of oy, usually accompanied by color epithets such as aq = white or boz = grey, are the Turkic terms; significantly, in Turkish - the Turkic of Turkey - where the bulk of the population has long led a settled life, the word, in the form of ev, has acquired the connotation of house; the Mongol word for our "yurt" is ger). The yurt radically differs from other nomads' tents - Arab, Berber, those of Iran, the tepee of the American Indian - both in shape and construction material; the shape is that of a round structure covered by a hemispherical or conical roof, with a smoke hole at the top, which can be closed with a flap; the material consists of a wooden trellis frame covered with a layer of felt, ideal i...
