Millions of Jellyfish Die from “The Blob”

Millions of Jellyfish Die from “The Blob”

Julia Parrish, a University of Washington professor, using 20 years of data from citizens who reported on coastal conditions all along the West Coast, found that mass die-offs of sailor jellyfish correlated with “the blob,” a patch of unusually hot ocean waters in the Pacific, according to a new study. 

Why this Matters: The Blob became prevalent in 2013 when surface waters off the Pacific coast began getting especially warm.

Portraits of Change: Climate Change Is Challenging Fishing in the U.S.

This week, we have featured this series of videos by the Environmental Defense Fund about the impacts climate change is having on the ocean as observed by the people who live and work there — fishermen and women. Their stories have been compelling and provided a sense of the ways that climate change is harming and shifting global fish stocks. 

Why This Matters:  On Tuesday, pursuant to President Biden’s climate executive order, NOAA announced: “an agency-wide effort to gather initial public input” on “how to make fisheries, including aquaculture, and protected resources more resilient to climate change.

Atlantic Ocean Currents Appear To Be Changing; So May Hurricane Season

Atlantic Ocean Currents Appear To Be Changing; So May Hurricane Season

In a little-noticed report that could have major implications for both the Eastern U.S. and Europe, scientists announced last week that Atlantic Ocean currents are thought to be 15% weaker than in 1950The Washington Post explained, saying that the “system of currents that includes the Florida Current and the Gulf Stream, is now ‘in its weakest state in over a millennium.'”

Why This Matters: We need to understand both these phenomena better to predict climate events.  They are quite a coincidence.

Experts Believe Spike in Shark Attack Deaths May be Caused by Climate Change

Experts Believe Spike in Shark Attack Deaths May be Caused by Climate Change

by Amy Lupica, ODP Contributing Writer  Sharks have killed seven people in Australia in 2020, the most since 1934, and scientists believe climate change might be responsible. According to the Taronga Conservation Society Australia, for the past 50 years, the average number of yearly shark attack fatalities was one. Despite the total number of shark […]

Climate Change Impacting Fish Spawning, While Not Enough Habitat Is Protected By Fisheries Managers

Climate Change Impacting Fish Spawning, While Not Enough Habitat Is Protected By Fisheries Managers

We know that rising ocean temperatures are causing fish stocks to migrate to cooler waters, and now we have new evidence as to why.  A study by German scientists found that juvenile fish and fish that are ready to mate are especially sensitive to changes in water temperature, and as a result, up to 60 percent of all species may be forced to leave their traditional spawning areas as waters warm.

Why This Matters:  Fish populations need functional habitat to survive and procreate.

Two Blobs – Both Scary – One Dying and One Now On Display

Two Blobs – Both Scary – One Dying and One Now On Display

In September, when ocean temperatures were five degrees above normal, scientists at the National Oceanic and Atmospheric Administration (NOAA) feared the re-emergence of a large ocean heatwave in the Pacific, which was known as “The Blob” when it formed before in 2014-15 and wreaked havoc with ocean ecosystems and wildlife at the time.  But due to a major shift in the weather pattern in the Gulf of Alaska, this year’s warm ocean water “blob” has begun to weaken and is expected to continue to lose strength as storms in the Pacific churn up colder water. 

Meanwhile, a blob of another variety went on display over the weekend at the Paris Zoo — and according to Popular Mechanics, it isn’t an animal, plant, or fungus, it has 720 sexes but no brain, loves oatmeal and is a billion years old.
