Excerpts;

Strong winds are driving the ocean’s biggest waves to dizzying new heights.

That’s the potentially ominous finding of new research that analyzed more than 30 years’ worth of global wind and wave measurements to see how they changed over time. The University of Melbourne researchers behind the work, published April 25 in the journal Science, say the supersized waves could compound the effects of rising sea levels, leading to more frequent flooding and accelerated coastal erosion…

Excerpts;

As the impacts of climate change escalate, ecosystems will likely undergo events that will disrupt entire populations. In marine ecosystems, anthropogenic warming has subjected organisms to elevated temperatures, oxygen loss, and acidification. The increased frequency and severity of catastrophic events may inhibit a population’s ability to recover and, in turn, may spur collapse…
