Two Tales of Acidification–The Old and the New
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.
Ancient Climate Change Records Discovery
Naturally occurring climate change lowered oxygen levels in the deep ocean, decimating a broad spectrum of seafloor life that took some 1,000 years to recover, according to a study that offers a potential window into the effects of modern warming…. Read More ›
Gulf Stream Weakening Could Impact Weather and Marine Ecosystems
Editor’s Note: Neptune 911 has included several videos that include animations of the Atlantic overturning system and scientific workshops. The Atlantic overturning is one of Earth’s most important heat transport systems, pumping warm water northwards and cold water southwards. Also… Read More ›
A Short Winter for the Arctic
(Reuters) – Arctic sea ice this year is the smallest in winter since satellite records began in 1979, in a new sign of long-term climate change, U.S. data showed on Thursday. The ice floating on the Arctic Ocean around the… Read More ›
Researchers Debate Upwelling Variance by Climate Change
CORVALLIS, Ore. – A report to be published Thursday in the journal Nature suggests that global warming may increase upwelling in several ocean current systems around the world by the end of this century, especially at high latitudes, and will… Read More ›
Low Oxygen and Warming Seas Historical Research
“Our modern ocean is moving into a state that has no precedent in human history.”
UCSB Research Report: Ocean Wildlife Armageddon Possible
…our knowledge of the ocean and how we are affecting it is lacking – we have explored less than 5% of the ocean, so the official number of species human activity has wiped out could be much higher.
Researching Corals in Acidic Ocean
A key reef-building coral that can survive a more acidic ocean is giving scientists hope that the world’s reefs stand a chance against climate change. An international team of researchers has been using baby corals from the Great Barrier Reef… Read More ›
Ocean Health Report Card: D Grade
one reason the overall scores ticked up since 2012 was because conservation measures have been gaining some ground and slowing some of the decline that has occurred since the preindustrial era. New marine protected areas have also “made a big difference,”
