Hi Doug,

Thanks for the heads up on that paper. I especially liked two of their primary concepts.

The idea of framing the restoration of marine ecosystems as a “doable Grand Challenge” for humanity and the coining of the term “recovery wedges” which are defined as complementary actions which when stacked together help raise the recovery rates of various ecosystem components. Mitigating climate change, removing sources of water pollution and addressing over-fishing are described as “basal wedges” which are required to set coral reefs on a recovery trajectory.

My question to you and other listers is this: Considering that here in the USA, the new administration seems to be determined to take a leadership role on climate change.

Is “substantially rebuilding marine life within a human generation largely achievable, if the required actions, prominently mitigating climate change, are deployed at scale”?

Thoughts?

Regards,

Steve

The discussion has a long paragraph on coral reefs that begins with the

statement: "Rebuilding coral reefs carries the highest risk of failure."

Cheers, Doug

The toxic effects of air pollution are so bad that moving from fossil fuels

to clean energy would pay for itself in health-care savings and

productivity gains

—

even if climate change didn’t exist. In the US alone, decarbonization

would save 1.4 MILLION lives in the US alone. And save $700 Billion a year.
