Climate alarmists claiming a collapse of ocean ecosystems caused by global warming from CO2 emissions might want to consider some facts before their scaremongering.

"In summer 2020, the media hyped various versions of “Tropical Oceans Headed For Collapse Within The Next 10 Years”.
One outlet warned, “Global warming is about to tear big holes into Earth’s delicate web of life.”
A single peer-reviewed paper instigated those apocalyptic headlines predicting CO2-caused warming would ramp-up species extinctions starting in tropical oceans.
In contrast, I’ll confidently bet any climate scientist $1000 that no such thing will happen.
...“Thanks to wise hunting regulations, Hawaii’s endangered humpback whales grew from just 800 individuals in 1979 to 10,000 by 2005.
Turtle nests in Florida increased from “62 in 1979 to37,341 in 2015” as North and South Atlantic green turtle populations increased by 2,000% and 3,000% respectively.”
“Critical photosynthesizing algae, diatoms, rapidly flourish when up welling brings nutrient rich, high CO2 deep waters back to sunlit surfaces.
Diatom blooms stimulate zooplankton abundance which feeds fast-growing bait fish, like anchovies and sardines, thus sustaining a food web from tuna to whales.
And more good news, since the 1850s warming has spurred dramatic increases in up welling and marine life.
Michael Mann and Kevin Trenberth ... recently co-authored a ‘scary’ paper titled Record-Setting Ocean Warmth Continued in 2019.
Using the energy metric Zetta (1021) Joules, an incomprehensible foreign language for the public, they estimated 2019 warmed by 25 Zetta Joules.
That converts to a not so scary 0.016 °F (0.009 °C) increase.
Five thousand years ago, marine organisms thrived in waters that were about 2.7°F to 3.6°F warmer than today.
At their alleged ‘record setting’ warming pace, it would take four to six hundred years to reach those earlier temperatures.”
...To be fair, it’s extremely difficult to measure the oceans’ heat content.
To improve our knowledge, a world-wide array of floating buoys, ARGO, was established by 2003 to measure temperature down to 2000 meters and periodically transmits data via satellite.
We now realize ocean currents are far more complex than once thought, and due to constant changes in ocean heat transport, such as caused by El Niño, the ocean heat content requires distinguishing warmer temperatures due to heat redistribution versus warming from the sun or CO2.
Un-predicted by climate models, ocean heat transport caused 90% of recently increased ocean heat to accumulate in a narrow band of the Southern Ocean outside the tropics, while the rate of northern hemisphere warming is decreasing.
However, ARGO data also reported cooler temperatures than previous less reliable ship measurements.
Oddly, 0.216°F is added to the ARGO data. Such a large adjustment makes the estimated increase of 0.016°F/year highly uncertain.
... Outside the tropics, the earth loses more heat than the sun or a greenhouse effect can provide.
It’s the transport of heat towards the poles that keeps temperatures outside the tropics much warmer than they would be otherwise.
... Ocean oscillations that increase ocean heat transport today most likely explain the Arctic warming of the 1930s."
