“Marine heat waves and
hot spots can have severe local effects, as ocean life struggles to survive the
increasing temperatures or moves to find cooler water, disrupting the
ecosystems in those places. But the bigger picture is that any change to the
ocean engine will matter, because the way this engine hums dictates conditions
for the rest of life on Earth. Living on a blue planet isn't about the color,
lovely though it is. The ocean is the dominant feature of Earth, and we live in
its shadow. This is about our identity as citizens of an ocean world, which is
broadcast to the universe, written in blue light.”— British
physicist and oceanographer Helen Czerski, “The Shifting Flows of
Our Overheating Oceans,” The Wall Street Journal, Sept. 30-Oct. 1, 2023
