So California and the rest of the southwest have been dealing with a “megadrought.” California responds to it with fires and riots and water bans and mass lootings (some of those are perennial California favorites drought or no drought). But now they have something new to complain about:

A disastrous megaflood is coming to California, experts say, and it could be the most expensive natural disaster in history

Claim is that thanks to climate change (remember: the carbon dioxide being burped into the atmosphere these days is disproportionately at the hands of China and India) a weather event that floods all of central California could come in the next 40 years and could recur every 50 years or so. If that’s the case, California would do well to prepare: Excavate new, vast reservoirs. Build aqueducts from likely flood zones to rivers and that great big ocean they’re sitting next to.
