A brief primer on lithium mining

Lithium, a soft white metal (photo, left), is a key material for electrical car batteries — making it a strategic material. The world’s currently known commercial-grade deposits are concentrated in South America and Australia. Mining methods on the two continents couldn’t be more d[...]

Victory for Klamath River dam removals

Historically, the Klamath River (map, left) was the third most productive salmon river in the lower 48 states, behind the Columbia and Sacramento rivers, Wikipedia says (here).

Does the Ivory-Billed Woodpecker still exist?

Why do Republicans hate electric cars?

“The Biden administration has made support for EVs a top priority,” Huffington Post says (here), and that’s probably enough reason right there. In today’s tribal politics, at least on the Republican side, “if they’re for it, we’re ag’in it.” But [...]

Dining in Venice

This photo is a bit unfair, because St. Mark’s Square isn’t always underwater, only during the seasonal high tides. And the flooding isn’t solely caused by sea level rise due to climate change; the ground under the city is sinking. Read why here. But what you see here is perhaps sy[...]
