Ocean Circulation Implicated in Past Abrupt Climate Changes

glaciers

A paper co-authored by BIOS President and CEO William Curry found that there was a period during the last ice age when temperatures in the Northern Hemisphere went on a rollercoaster ride, plummeting and then rising again every 1,500 years or so. Those abrupt climate changes wreaked havoc on ecosystems, but their cause has been something of a mystery.

With Coral Reefs in Hot Water, Bermuda Could be a Safe Haven

Elevated ocean temperatures have threatened coral reefs around the world for over a year, but this October marked a tipping point. NOAA scientists declared the onset of a global coral reef bleaching event impacting coral reefs in every ocean basin, and projected the bleaching will only intensify in 2016. This is the third such global bleaching event in history

New Study Links Global Ocean Processes with Local Coral Reef Chemistry

Five years of data collected on reefs and offshore in Bermuda shows that coral reef chemistry – and perhaps the future success of corals – is tied not only to the human carbon emissions causing systematic ocean acidification, but also to seasonal and decadal cycles in the open waters of the Atlantic, and the balance of biochemical processes in the coral reef community
