The European Union’s Earth observation program, Copernicus, just recorded the hottest June on record for the world’s oceans, with both the Mediterranean and the Pacific Ocean holding more than 10 degrees Fahrenheit hotter than usual. It might make surf-going a little more (or less) pleasant, depending on where you might find yourself this summer, but naturally, there are other, graver implications.
The Copernicus Marine Service data “help track the development of marine heatwaves, support the assessment of ocean conditions, and the monitoring of potential risks to marine ecosystems globally,” per the EU Space Policy website.
“These records reflect a climate system continuing to accumulate heat,” Samantha Burgess, deputy director of the Copernicus Climate Change Service, said in a statement. “The result is increasingly intense heatwaves, a persistently warm ocean, and growing risks for people, ecosystems, and infrastructure across Europe and beyond.”
May’s records saw a similar heatwave. Take climate change, chaos, or general capricity as you will—and blame it on what you will—but data shows that these conditions would have bordered on the impossible just 50 years ago, per the World Weather Attribution initiative.
And again, despite causes and/or aggravating factors, “Many people still live, work, and study in places that are not designed for the temperatures we are now experiencing,” the Red Cross Red Crescent Climate Centre said in a statement at the end of June. “We need greater investment in heat-resilient homes, cities, and infrastructure to keep people safe.”
As vast parts of Canada and densely packed parts of Western Europe undergo unprecedented evacuations of hundreds of thousands of residents, current infrastructure indeed calls for reconsideration.
Back to our element, though, hotter oceans mean dying organisms, like the reefs that shape our waves, and the fish that feed us and ours. They also mean less-predictable forecasts, which means less-predictable surf seasons and windows.
It’s safe to say we’ll still have waves—and likely plenty if not more of them, but the matters of when and where, and why, are likely to become bigger and bigger question marks.
