👏 Heroic effort to extract a H₂ record from ice cores 👏
The samples had to measured in the field immediately after drilling (i.e. fresh out the oven 🥮) to prevent the tiny H₂ molecules from leaking out.

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.
