Researchers confirm existence of North Icelandic Jet current; implications for ocean response to climate change

Green Car Congress

An international team of researchers has confirmed the presence of a deep-reaching ocean circulation system off Iceland—the North Icelandic Jet (NIJ)—that could significantly influence the ocean’s response to climate change in previously unforeseen ways.

Rice researchers show ocean could have contained enough methane to cause drastic climate change 56M years ago

Green Car Congress

Analysis by researchers at Rice University suggests that the theory that the release of massive amounts of carbon from methane hydrate frozen under the seafloor 56 million years ago drove a massive climate change incident—the Paleocene-Eocene Thermal Maximum (PETM)—is quite possible.
