Arctic sea-ice extent just passed the border into the "record-low" domain.
Same for Barents, Baffin, Hudson, and Svalbard regions.
Second-lowest globally.

This study by my colleagues at University of Hawaiʻi at Mānoa shows that deep sea mining waste to be released near the ocean surface would disrupt marine food webs.

The same would be true of grinding and spreading rocks in the ocean for CO₂ removal. 🌊
