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.

Ocean Warming Causing Fish Migrations and Strife

Ocean Warming Causing Fish Migrations and Strife

Warming ocean temperatures are causing fish populations to migrate north, complicating fisheries management and fishing businesses that are not able to keep up because the fishery-specific regulations and catch quotas are regional and they no longer align with where the fish are being found.

Marine Species in the Pacific Are Climate “Migrants”

The Pacific Coast of Northern California is finding a new sort of climate refugee washing up on its shores and inhabiting its bays and coastal waters — species that have shifted their migratory patterns and habitat due to warming ocean waters throughout the Pacific.
