We have a new keyboard, Chester Creek Wireless Vision keyboard, with bigger keys. I have dinner guests. More tomorrow.
“Throughout history, poverty is the normal condition of man. Advances which permit this norm to be exceeded—here and there, now and then—are the work of an extremely small minority, frequently despised, often condemned, and almost always opposed by all right-thinking people. Whenever this tiny minority is kept from creating, or (as sometimes happens) is driven out of a society, the people then slip back into abject poverty.
“This is known as ‘bad luck’.”
– Robert A. Heinlein

After this great glaciation, a succession of smaller glaciations has followed, each separated by about 100,000 years from its predecessor, according to changes in the eccentricity of the Earth’s orbit (a fact first discovered by the astronomer Johannes Kepler, 1571-1630). These periods of time when large areas of the Earth are covered by ice sheets are called “ice ages.” The last of the ice ages in human experience (often referred to as the Ice Age) reached its maximum roughly 20,000 years ago, and then gave way to warming. Sea level rose in two major steps, one centered near 14,000 years and the other near 11,500 years. However, between these two periods of rapid melting there was a pause in melting and sea level rise, known as the “Younger Dryas” period. During the Younger Dryas the climate system went back into almost fully glacial conditions, after having offered balmy conditions for more than 1000 years. The reasons for these large swings in climate change are not yet well understood.
