enormous impacts: “If we deploy 4000 pumps—this will reduce approximately 1 million tons (a megaton) of CO2. We estimate that four mil- lion pumps deployed would sequester about 1 billion tons of

CO2 (a gigaton).”

At the same time, only further investigation can make ocean

CDR a reality. “We need more responsible experiments and deliberate and pervasive monitoring of the ocean carbon cycle. These experiments themselves would not cause ir- reparable harm to the ocean, but it’s essential to make smart choices about how to reduce suffering and loss due to climate change,” Buesseler said.

Federal, academic and philanthropic research and support are crucial for the commercialization and mass rollout of

CDR techniques.

With only 28 years until 2050, the clock is ticking. Ocean

CDR presents an attainable and effective way to enhance and accelerate natural carbon processes and a possible game- changing solution to reduce emissions. As Buesseler puts it aptly, “The alternative—doing nothing—is a path we are on today that has severe consequences for humanity.” h d Wals h h ha ha har by by Richard Wals P to by Phot by by by Richard Wals Photo by Richard Wals P P Pho o o by Ric ic ic ichar ar rd W W Wals ls l lsh, h, h h, h, h, h h,
