Busting a polar bear myth

Background: Polar bears are a symbol of the deleterious effects of global warming.

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

A river runs through a controversy that has brewed for 20 years, but is now coming to closure. 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). During the 1850s, gold seeke[...]

Does the Ivory-Billed Woodpecker still exist?

It might be a snipe hunt, but true believers aren’t giving up. After all, if it’s not a real bird, it once was. And that’s the question; last seen in 1944 for sure, North America’s most elusive bird may not be around anymore, except for stuffed specimens in museums (photo bel[...]

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[...]
