The Download: ocean-based carbon removing, and Musk’s untweeted journey to China

The information: A nonprofit shaped by Mike Schroepfer, Meta’s former chief know-how officer, has spun out a brand new group geared toward dashing up analysis into ocean alkalinity enhancement—a possible method to make use of the seas to suck up and retailer away much more carbon dioxide. The Carbon to Sea Initiative will get $50 million over the following 5 years to pursue that aim.

How it really works: Ocean alkalinity enhancement refers to varied methods of including alkaline substances, like olivine, basalt, or lime, into seawater. These fundamental supplies bind with dissolved inorganic carbon dioxide within the water to kind bicarbonates and carbonates, ions that may persist for tens of 1000’s of years within the ocean. As these CO2-depleted waters attain the floor, they will pull down further carbon dioxide from the air to return to a state of equilibrium. 

Why it issues: While such initiatives could be difficult to scale, local weather modelers are optimistic concerning the technique’s potential. Read the full story.
