Ocean-based carbon removing, and Musk’s untweeted journey to China



The information: A nonprofit fashioned by Mike Schroepfer, Meta’s former chief expertise officer, has spun out a brand new group aimed toward rushing up analysis into ocean alkalinity enhancement—a possible approach 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 subsequent 5 years to pursue that purpose.

The way it works: Ocean alkalinity enhancement refers to numerous 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 type 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’ll pull down further carbon dioxide from the air to return to a state of equilibrium. 

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