    “I will show you fear in a handful of dust”*…

    More than 40 percent of the global population, more than 2 billion people, have a dust problem. Not “dust” meaning the grey puffs under the couch, but the dust of the Dust Bowl: microscopic soil particles, less than 0.05 millimeters across, so small that they get hoisted up into the wind and end up in people’s lungs.

    We know that large amounts of dust are linked to premature death. However, climate change is expected to make the problem much worse in the next century, and scientists still don’t know how much. In the next century, the lethal range of dust is expected to proliferate. Between now and 2050, the many as 4 billion people, half the world’s population, are expected to live in drylands. It’s not because people are migrating there. Drylands are growing because of (you guessed it) climate change

    Dust is known to cause premature deaths, but climate change’s effect on how bad our dust problems will get remains notoriously understudied: “A global Dust Bowl is coming.”

    As we do our best to go green, we might send grateful birthday greetings to Arthur Hinton “Art” Rosenfeld; he was born on this date in 1926.  A physicist at U.C Berkeley, he was moved by the oil embargo of 1973 to turn his attention to energy conservation, founding and leading the Center for Building Science at the Lawrence Berkeley National Laboratory.  Over the next 37 years he developed new standards which helped improve energy efficiency in California and subsequently worldwide.  His work helped lead to such breakthroughs as low-energy electric lights, such as compact fluorescent lamps, low-energy refrigerators, and windows that trap heat.  In his fight against global warming, he saved Americans billions of dollars in electricity bills– and earned the nickname, “godfather of energy efficiency.”

    As we turn up the air conditioner, we might spare a thought for Sir Karl Raimund Popper; he died on this date in 1994.  One of the greatest philosophers of science of the 20th century, Popper is best known for his rejection of the classical inductivist views on the scientific method, in favor of empirical falsification: A theory in the empirical sciences can never be proven, but it can be falsified, meaning that it can and should be scrutinized by decisive experiments. (Or more simply put, whereas classical inductive approaches considered hypotheses false until proven true, Popper reversed the logic: conclusions drawn from an empirical finding are true until proven false.)

    Popper was also a powerful critic of historicism in political thought, and (in books like The Open Society and Its Enemies and The Poverty of Historicism) an enemy of authoritarianism and totalitarianism.
