8 of the top 10 U.S. cities that have seen an increase in nuisance flooding, which causes road closures, overwhelmed storm drains and compromised infrastructure, are on the East Coast, according to a…

There's a concern that global warming may push Earth's climate system past a "tipping point," where rapid melting of ice and further warming may become irreversible. It's a hotly debated conjecture…

It sounds like it should be easy enough to know if ice is growing or retreating, but it really isn't.  Antarctic sea ice has been expanding, we are told, while Arctic sea ice is retreating, both…

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…
