The slice of land that has supported the Biloxi-Chitimacha-Choctaw Indians through trapping fishing, and agriculture for 170 years is rapidly being swallowed by the Gulf of Mexico.
So what is going on? Is global warming beginning to cause more frequent and intense El Niños? And what effect might more powerful El Niño cycles have on the planet’s steadily warming climate?
“The findings are concerning. It’s clear evidence that the oceans are taking the brunt of the greenhouse gases and are accumulating a lot of heat. As for the ecological implications, that’s hard to say. There is a lot of life in the deep oceans and there’s lots we don’t know about the impact upon that life.”
Tropical coral reefs cover less than 1% of the ocean, but they are home and nursery to 25% of all marine species; billions of fish, mollusks and other creatures rely on reefs for their food and shelter. Their wonder and beauty generates needed tourism dollars for many poor nations, and they act as natural barriers providing storm surge protection for many millions of coastal residents.
David Lusseau, senior lecturer in Marine Top Predator Biology at the University of Aberdeen, told IBTimes UK this does appear to be the largest whale stranding for any type of baleen whales. He said: “I do not know of other events with such large numbers of individuals involved. Seeing multiple sei whales stranded together in clusters is beyond the ordinary.”
“Overall, we found there’s a decrease in species diversity and abundance irrespective of what ecosystem we are looking at. These are broad scale impacts, made worse when you combine the effect of warming with acidification.
According to a 2013 study, marine species are pushing their range boundaries poleward, away from the Equator, at an average speed of 4.5 miles a year. That’s 10 times as faster as the speed at which species on land are moving.
by nicola jones In Hawaii this summer, as corals engage in their once-a-year courtship ritual of releasing sperm and eggs into the water by moonlight, Ruth Gates will oversee a unique mating: the coming together of “super-corals” in her lab…. Read More ›
If you thought the worst extinction event on Earth was the one that killed the dinosaurs some 66 million years ago, think again. A far worse event, the Permo-Triassic Boundary mass extinction event, happened some 252 million years ago, which over the course of about 60,000 years is thought to have wiped out more than two-thirds of land species and more than 90% of marine species on the planet.
