“Barbed spearpoints” found nearby may have been tied to sticks and used to spear fish, said study co-author Marieka Brouwer Burg of the University of Vermont.

“The question is, what happens when you scale it up to billions of tons every year?” said David Ho, an oceanography professor at the University of Hawaii at Manoa and co-founder and chief science officer of the nonprofit (C)Worthy, which works on verifying the impact of ocean-based carbon removal.Planetary’s Burt imagines a future in which minerals are pumped out through power plants and water treatment facilities on every major coastline in the world. But that would require a large, steady volume of magnesium oxide or similar minerals, along with the energy to mine and transport them.

Seaweed and algae growth would need to expand exponentially. The National Academies of Sciences, Engineering, and Medicine has estimated that nearly two-thirds of the world’s coastline would need to be encircled by kelp to even begin to make a dent in global warming. The company Seafields, which is running tests in the Caribbean, says it envisions building a Sargassum farm between Brazil and West Africa more than 200 miles wide.There’s the risk that these expansions exacerbate environmental harm that isn’t detectable in small trials, and because of global water circulation, could be felt around the world.But the alternative to never trying, Ho said, is unabated climate change.

Griffin, 44, is facing mounting criticism – including from some Republicans – as he seeks toNASA has chosen Starship for its first two astronaut landings on the moon under Artemis, named after Apollo’s twin sister in Greek mythology.

When asked if Musk has contacted him since his nomination about how to manage NASA, Isaacman replied, “not at all.” Isaacman then was questioned how he would protect against undue influence from Musk, given SpaceX’s billions of dollars’ worth of contracts with NASA.“I absolutely want to be clear,” Isaacman said. “My loyalty is to this nation, the space agency and their world-changing mission.”

Isaacman said he supports continuing the International Space Station through 2030, as currently planned by NASA. Musk suggested earlier this year that the space station should be dumped as soon as possible in order to focus on Mars.When pressed by senators again before the hearing ended, Isaacman said the space station should keep going until it’s replaced by private outposts in orbit.
