Arctic sea ice has been rapidly declining since satellites first started tracking it in 1979, and according to NASA, roughly 13.3 percent of the ice disappears every decade. Models have projected that manmade global warming would heat the Arctic faster than it would heat more temperate regions, and observation has borne that out. The Arctic is warming at least twice as fast as the rest of the globe, and the first two months of this year both had the lowest levels of sea ice on historical record.
“To lose coral reefs is to fundamentally undermine the health of a very large proportion of the human race,” said Ruth Gates, director of the Hawaii Institute of Marine Biology
cientists say that the equivalent of a dump truck load of plastic is deposited in the world’s oceans every minute, and this quantity will only increase as consumption and population grow, too. By 2050, it’s said there will be more plastic than fish in the seas. The UN writes, “As many as 51 trillion microplastic particles – 500 times more than stars in our galaxy – litter our seas, seriously threatening marine wildlife.”
A large research synthesis, published in one of the world’s most influential scientific journals, has detected a decline in the amount of dissolved oxygen in oceans around the world — a long-predicted result of climate change that could have severe consequences… Read More ›
The amphipods were contaminated with PCBs — polychlorinated biphenyls — toxic chemicals used for decades in industry, as well as other industrial pollutants known as persistent organic pollutants.
“Every sample we had,” Jamieson says, “had contaminants in it at very high or extraordinarily high levels.”
“The situation is completely out of control,” says Lorenzo Rojas-Bracho, a cetacean expert at the National Institute of Ecology and Climate Change in Ensenada, Mexico, and member of the International Committee for the Recovery of the Vaquita, an international advisory group to the Mexican government. “Of course, there’s a risk in capturing the vaquitas. But it’s clear now that they will be killed [in gillnets] anyway.”
Farther south, the Bering Sea has emerged as a hot spot for warming-water studies — almost literally. Sea-surface temperatures in the Bering reached 14 degrees Celsius last summer (57 degrees Fahrenheit) and were generally 3 degrees Celsius (5 degrees Fahrenheit) warmer than normal, scientists reported.
