The idea that the Plutonium 238 could have moled its way into a glacier is mind-boggling (and not in a good way).

How Did the C.I.A. Lose a Nuclear Device in the Himalayas? (Gift Article)
A plutonium-packed generator disappeared on one of the world’s highest mountains in a covert mission that the U.S. will not talk about.

Excited to share our new PNAS paper!
We find that recent methane growth was driven by agriculture/waste and wetland emissions, while fossil fuel emissions have remained stable despite growth in production, highlighting recent progress and further mitigation potential.

A magical record! Now 3,000,000 years long! Repost this quote and see if it increases by another order of magnitude.
A new record of Arctic sea-ice coverage—informed by the slow and steady sedimentation of cosmic dust on the sea floor—reveals that ancient ice waxed and waned with atmospheric warming, not ocean heat, over the last 300,000 years.
