Most people have experienced a heat wave on land. But heat waves can strike in the ocean too. And as the planet continues to warm, marine heat waves are growing longer and deadlier, hurting the seafood supply that billions of people worldwide rely on for their food and livelihoods.

Researchers at Michigan State University say a controversial strategy to shield Earth from some of the sun’s rays would offer unequal protection for the oceans and communities that depend on them, leaving 25% to 75% of the world’s seas still at risk from overheating, models suggest.

…

“The degree of protection depends on how aggressively it is deployed,” Kounta said.

Under the moderate scenario, only 20% to 25% of the ocean was shielded from worsening heat waves. But under the more aggressive scenario, those numbers jumped up to 75%.

1. Could a controversial cooling strategy interrupt CO2 uptake by Earth's oceans? No.

Then what are we talking about this for?

2. The immediate peril is heat

Ocean acidification is a little longer term.
