The US ice core research community, with international partners, has recovered valuable records of past climate from the Arctic & Antarctic since the 1950s.
Here is a sampling of cores—including 6,000,000 year old ice via NSF Center for Oldest Ice Exploration—at the NSF Ice Core Facility.

It’s wild how hard it seems for Austrian journalists to clearly describe road violence. A driver ran over a cyclist and killed her. She didn’t “collide” with a car. The car didn’t move on its own. A driver killed her while she was waiting to turn — high-viz, helmet, lights on.

“It’s the industry that has driven the demand through huge marketing & advertising campaigns in recent years. SUVs offered the industry a simple way of charging more for a vehicle that does the same thing.”
