Sharks Face Growing Threat Warming and Acidic Seas

Climate Central: Shark Week, the annual television extravaganza featuring the most terrifying and toothiest fish in the sea, will wind down over the weekend. But even though sharks may disappear from the collective consciousness for another year, that doesn't mean they'll cease to exist. Like many species, sharks face a looming threat: a changing climate. The most ancient sharks date back to 450 million years ago, during a period when the oceans were much warmer and much more acidic -- an environment today's sharks...

Canadas Beaufort Sea is becoming acidic more quickly than any other ocean in the world
2015-06-23 16:00:00| Climate Ark Climate Change & Global Warming Newsfeed
National Post: Research suggests Canada`s Beaufort Sea is becoming acidic more quickly than any other ocean in the world, offering a window into what a major side effect of climate change will do to waters around the globe. "As goes the Arctic, so go the rest of the oceans," said Jeremy Mathis of the U.S.-based National Oceanic and Atmospheric Administration, lead author of the new paper published in the journal Oceanography. In about 10 years, he predicts the Arctic waters off the Northwest Territories will...
Acidic oceans helped fuel extinction
2015-04-09 22:21:00| Climate Ark Climate Change & Global Warming Newsfeed
BBC: Acidic oceans helped fuel the biggest mass extinction in the history of life on Earth, a study says. The exact causes behind the Permian-Triassic mass extinction have been much debated. Two separate pulses of CO2 into the atmosphere - a "one-two punch" - may have helped fuel the die-off, new research suggests. Changes to ocean acidity would have been one of the consequences, according to the study in Science journal. Computer models suggested that this CO2 may have been released by massive...

Acidic oceans implicated in Earth's worst mass extinction
2015-04-09 20:20:00| Climate Ark Climate Change & Global Warming Newsfeed
Reuters: It is one of science's enduring mysteries: what caused the worst mass extinction in Earth's history. And, no, it is not the one that wiped out the dinosaurs. Scientists said on Thursday that huge amounts of carbon dioxide spewed from colossal volcanic eruptions in Siberia may have turned the world's oceans dangerously acidic 252 million years ago, helping to drive a global environmental calamity that killed most land and sea creatures. The researchers studied rocks in the United Arab Emirates...

Greatest mass extinction driven by acidic oceans, study finds
2015-04-09 12:00:00| LifeSciencesWorld
[NEWS] Changes to the Earth's oceans, caused by extreme volcanic activity, triggered the greatest extinction of all time, a study suggests.The event, which took place 252 million years ago, wiped out more than 90 per cent of marine species and more than two-thirds of the animals living on land. It happened when Earth's oceans absorbed huge amounts of carbon dioxide from volcanic eruptions, researchers say. This ch…
