Fish and other sea life have been heading toward the Earth’s poles for more than three decades, a mass migration to cooler waters that provides more evidence of a rapidly warming planet and has repercussions for fish harvests around the globe, according to a first-of-its-kind study released Wednesday.
The study, in the journal Nature, found that significant numbers of 968 species of fish and invertebrates examined by University of British Columbia researchers moved to escape the warming waters of their original habitats. Previous studies had demonstrated the same phenomenon for specific places in the world’s oceans. The authors said their research is the first to assess the migration worldwide and to look back as far as 1970.
The research is more confirmation that “global change is real and has been real for a long time. It’s not something in the distant future. It is well underway,”said Boris Worm, a professor of marine biology at Dalhousie University in Halifax, Nova Scotia, who was not part of the study.
This blog has become a place where I post articles that I find related to global warming - causes and effects, as well as a few other topics - related or not.
Jellyfish are like poster-boys of global warming changes - jellyfish are one species of animal that are doing very well. The increased acidity of the oceans, warmer waters, the decrease in predators as fish and other wildlife decline have all favored jellyfish. They seem to thrive on the fertilizers that people have been washing into the seas. Most animals do not.
I also like to post discoveries - especially discoveries that are being made out in space as people are able to see farther and farther galaxies and nebulas and supernovas. Even though I don't think that people will ever go live any of those places - I just like knowing that they are out there. It's part of keeping in mind that the earth and it's inhabitants are such a small part of what is going on in the universe.
I have another blog with posts on art and artists - it's called M'S IMPRESSIONS.
