Year 4, Month 9, Day 22: Why People Tear The Seam Of Anyone’s Dream Is Over My Head
Oceanic ecosystems are coming undone, notes the LA Times:
As climate change heats our oceans, you’d expect temperature-sensitive marine species to flee poleward to cooler waters. So why have some headed to warmer regions toward the equator?
Scientists have solved the puzzle. For the most part, these animals are relocating to cooler waters. But since the effects of climate change can vary widely across regions, sometimes those cooler regions are closer to the poles and sometimes they’re closer to the equator.
In other words, marine animals are still reacting to climate change, but at a local scale. And they’re doing it so reliably that you can actually measure the speed and direction of those changes by watching where animals go, according to a study published Thursday in the journal Science.
Just another day in the Solar System. September 14:
As climate change’s effects grow more intense, we’ll see more plant and animal species on the move; the transformation of the world’s ocean populations is just one example of something that’s happening everywhere we look. But the heart of the story isn’t that creatures are traveling to more salubrious locales. The intricacy and variety of Earthly life is created by the interactions between life-forms; local and regional habitats have evolved over thousands of years to support symbiotic relationships in a richly interwoven tapestry.
A particular type of fish moving where the water is cooler doesn’t sound like that big a deal — but it could easily spell disaster for other species in an interdependent oceanic environment. When the web of life unravels in one location, it will have impacts everywhere. With billions depending on the seas for their sustenance, the news of ecosystem disruption is bad news for everyone.

Year 4, Month 2, Day 14: And Because I Love You, I’ll Give It One More Try
The North Andover Eagle-Tribune reports on climate change in New England:
One of the harbingers of change has been the lobster industry, which Wahle called a kind of “canary in a coal mine.”
Maine fishermen have set record harvests over the past few years, perhaps due in part to higher water temperatures and fewer groundfish, which prey on young lobsters. Fishermen off Newburyport have also reported good harvests, with last year being among the best.
Meanwhile, in southern New England, it’s an entirely different story. Mass lobster kill-offs in Long Island Sound have been caused by warming waters, Wahle said, while a disease that infects lobster shells has been spreading northward through the sound and into Massachusetts waters.
“(The disease) seems to have stalled out just south of Cape Ann,” Wahle said.
If the disease spreads further north, it could have a devastating impact on northern New England’s lobster fisheries, Wahle said.
As of Feb. 6, the comment thread on this article was 100% denialist stupidity. Sent, with an optimistic tag:
New England’s not alone in feeling the increasing impact of global warming. While specific symptoms of climate change vary from place to place, regions everywhere around the planet are affected. Whether it’s drought in the corn belt, unseasonal monsoons in Asia, or warmer winters fostering pine beetle infestations in Colorado, the consequences of the greenhouse effect are hitting people painfully. Some communities may reap temporary benefits — like Maine lobstermen who are hauling in a bumper harvest — but since warmer winters may bring an end to the state’s skiing industry, there’s no real positive economic impact on a wider scale.
If there is any upside to the accelerating climate crisis, it is that our species’ future requires us to realize that what we do today in our own narrow corner of the world will affect people thousands of miles — and hundreds of years — away. Only by recognizing that political boundaries and cultural differences are irrelevant in the face of the gathering storm can we humans make a happy and prosperous future for our posterity.
