“There is an emerging sense that the oceans do have some resilience, and while they are changing in response to climate change, we don’t see evidence that marine heat waves are wiping out fisheries,” said Alexa Fredston, the lead author of the study…
The analysis included 248 marine heat waves with extreme sea bottom temperatures during this period [1993-2019]. The researchers were surprised to find that marine heat waves in general don’t show major adverse effects on regional fish communities…
Overall, they found that the effects of marine heat waves aren’t distinguishable from the natural variability in these ecosystems.
If this were the late 1960s or1970s.i might agree with this sentence. As it is, it makes me think this research is funded by climate change deniers.
In humans “the resilience” is called “homeostasis”. In ecosystems it’s called “climax”.
This steady state is maintained until some critical threshold is crossed… And the system shifts to a different (new) homeostasis, climax.
In humans this is called chronic disease.
What is it called when an ecosystem shifts to a different “steady state”?
Ie there’s nothing “emerging” about the concept of system resilience.
Nice thing about science is that one can learn something new. Nice thing about this research is that it is based on real data – almost 250 heat waves over a quarter of a century.

In other good ocean news, the Great Barrier Reef off Australia last year recorded its highest coral cover since monitoring began 37 years ago. Who knew?
