A new study indicates sea levels likely will continue to rise in the tropical Pacific Ocean off the coasts of the Philippines and northeastern Australia as humans continue to alter the climate. The…

As sea ice begins to melt back toward its late September minimum, it is being watched by researchers who have put sensors on and under ice in the Beaufort Sea.  The international effort hopes to…

A new study on biological erosion of mesophotic tropical coral reefs - low energy reef environments between 30-150 meters deep - provides new insights into processes that affect the overall structure…

Changes to Antarctic winds have been implicated in southern Australia's drying climate but a new estimate says they may also have a profound impact on warming ocean temperatures under the ice shelves…

Whales are relatively rare and so they probably don't make much of a difference in the overall ocean.  A team of biologists disagrees. They reviewed several decades of research on whales from…

Iron is one of the essential elements of life. Found in enzymes like myoglobin and hemoglobin and cytochrome P450, iron is an essential cog in the biomachinery of every living cell.  Iron is…

A paper in Scientific Reports posits a new cause of the ice age that covered large parts of the Northern Hemisphere 2.6 million years ago. The study found a previously unknown mechanism by which the…

If your glass is half full, you recognize that in recent geological history, 90,000 of every 100,000 years have been ice ages, and it's been 12,000 years since the last one. In that light, global…

If the Greenland ice sheet ever gets past its stability threshold, it won't be the first time.  400,000 years ago, a nearly complete deglaciation of southern Greenland happened, raising global…

The Greenland Ice Sheet is huge, a 1.7 million-square-kilometer, 2-mile thick layer of ice that covers Greenland. In the last 40 years, ice loss from the Greenland Ice Sheet has increased four-fold,…
