"Blame"?

Isn't that a value judgment, that it was a bad thing for the dinosaurs to become extinct? Maybe they should be talking about "credit."

And the volcanos and asteroids were just doing what volcanos and asteroids do.

You can blame them all you want, but they ain’t changing.

I’m guessing a socialist took over managing the dinosaurs, and shortly thereafter, they ran out of them.

Gary Larson, the Far Side, has already solved the question of dinosaur extinction.

But you could bet your ass that the Socialist Democrats would try to tax the crap out of them.

I think the dinosaur distinction was caused by a black hole.

No. Neither volcanoes nor asteroid are moral agents.

Indeed, we would have considered the alligator a dinosaur if that black hole had not interfered.

Asteroids by themselves are fairly benign, so for these to have caused so much mayhem, it probably had volcanoes on the Asteroid and I wouldn’t be surprised if an ancestor of a Tesla SUV wasn’t also on it to be so evil. /s <;^0

Fascinating information, ETL. I didn’t know the big basalt flows were known as “traps.”

The scale is unimaginably immense...
• 160 miles across
• Up to 1.2 miles thick
• Lasting up to one million years
• Climate-altering volcanic gases leak out of underground magma chambers frequently, and not just during eruptions
• The most recent basalt flow, near the Columbia River in the Pacific Northwest, dwindled 15 million years ago after 400,000 years of eruptions.

In geologic history, 15 million years ago and 65 million years ago is not very far back. Could similar basalt flows occur again? Would the gases emitted poison the atmosphere and doom mankind?

Has anybody tried to quantify the volume of “climate-altering gases leaking out of underground magma chambers” and compare it to man-made emissions? Is it possible that this leakage together with the sun is what really controls climate and man is making negligible contributions?

It’s the large basalt *rock formations* that are known as ‘traps’, “stair steps” in some foreign language.
