Is geography destiny? Jared Diamond’s Guns, Germs and Steel purports to explain why parts of the world got very rich and technologically advanced and then conquered the other bits. It did so using facts about the geography of Eurasia versus Africa and the Americas in particular: Notably, the prevalence of easily domesticated plants and animals, and a broadly east-west-aligned landmass, which allowed the rapid dissemination of technologies and crops. The book made some people very angry: They felt it was trying to absolve Europeans of their guilt for conquering the world. The historian Davis Kedrosky argues that it was trying to do no such thing, but that — more importantly — its thesis, even 26 years on, very much still holds water. Water, water everywhere, nor any drop to drink The Colorado River has dried up so much that the states, districts, and operators that take their water from it have had to agree to lower their demand by 13%. The Mississippi might be going a similar way. Rivers around the U.S. and the world are changing, some drying up, as the climate shifts. Casey Handmer, a former NASA engineer who now runs a climate technology business, argues that we can improve the supply of water, as well as curtailing demand. There exists cheap, scalable technology to desalinate sea water. “Reverse osmosis” techniques, powered by solar energy, can turn vast volumes of salt water into fresh. Pump that upstream, he argues, and refill the rivers. “We believe that water should be unconditionally abundant,” he says. “We could solve water scarcity not by choosing lots and killing entire industries, but by simply generating more water.” A lie can run round the world before the truth has got its boots on The political scientist Brian Klaas has a regret. He debated a conspiracy theorist on British radio once, about Donald Trump and the Hunter Biden-Ukraine corruption claims. Klaas claims to have “wiped the floor” with his opponent — but, by doing the debate on the conspiracy theorist’s terrain, worries he lost the war even if he won the battle, giving the Hunter-Ukraine link more air time than it deserved. In this piece he talks about the lessons he learned from that, and how best to combat disinformation. There are some useful ideas in there, although Flagship’s Tom wonders if Klaas is overthinking it: If someone is made to sound like an idiot on the radio, most listeners will probably tend to disbelieve what they say. |
