The rapid decline of ancient ice sheets could help scientists predict the impact of modern-day climate and sea-level change, according to new research.

Wind-driven expansion of marsh ponds on the Mississippi River Delta is a significant factor in the loss of crucial land in the Delta region, according to new research. The study found that 17 percent of land loss in the area resulted from pond expansion, …

Increasing water temperatures are responsible for the accumulation of a chemical called nitrite in marine environments throughout the world, a symptom of broader changes in normal ocean biochemical pathways that could ultimately disrupt ocean food webs.

The Witwatersrand basin in South Africa hosts the largest known gold repository on Earth -- but how was it formed? Scientists were able to figure out how parts of the Earth's largest gold deposits formed about three billion years ago. Crude oil and hot hy…

In the first ecosystem-wide study of changing sea depths at five large coral reef tracts in Florida, the Caribbean and Hawai'i, researchers found the sea floor is eroding in all five places, and the reefs cannot keep pace with sea level rise. As a result,…

The one-two punch of warming waters and ocean acidification is predisposing some marine animals to dissolving quickly under conditions already occurring off the Northern California coast, according to a new study.
April 19th
In the first such continent-wide survey, scientists have found extensive drainages of meltwater flowing over parts of Antarctica's ice during the brief summer.

A group of scientists offers photographic proof of climate change using images of retreating glaciers.
April 18th
Climate change is causing thick ice deposits that form along Arctic rivers to melt nearly a month earlier than they did 15 years ago, a new study finds.
April 17th
Researchers estimate that approximately 13.1 million people could be displaced by rising ocean waters, with Atlanta, Houston and Phoenix as top destinations for those forced to relocate.

Recent observations suggest less long-term warming, or climate sensitivity, than the predicted by climate models. But the mismatch is resolved by factoring in that Earth is still in the early stages of adjusting to greenhouse gases.

Researchers have identified glaciers in West Greenland that are most susceptible to thinning in the coming decades by analyzing how they're shaped. The research could help predict how much the Greenland Ice Sheet will contribute to future sea-level rise d…

Cretaceous climate warming led to a significant methane release from the seafloor, indicating potential for similar destabilization of gas hydrates under modern global warming. A field campaign on the remote Ellef Ringnes Island, Canadian High Arctic, dis…

Each year, young European eels make their way from breeding grounds in the Sargasso Sea to coastal and freshwater habitats from North Africa to Scandinavia, where they live for several years before returning to the Sargasso Sea to spawn and then die, begi…

What is the volume of water in lakes on Earth? Using a mathematical analysis, researchers now suggest that the mean depth of lakes is 30 per cent lower than previously estimated. Shallower lakes implies less fresh water and has consequences for our unders…

Microbes in streams flowing on the surface of glaciers in the Arctic and Antarctic may represent a previously underestimated source of organic material and be part of an as yet undiscovered 'dynamic local carbon cycle,' according to a new paper.
April 11th
A new study assessing the underwater soundscape off Southern California found that blue, fin and humpback whales experience a range of acoustic environments, including noise from shipping traffic as well as quieter areas within a national marine sanctuary…

When, in the foreseeable future, a tabular iceberg nearly seven times the size of Berlin breaks off the Larsen C Ice Shelf in the Antarctic, it will begin a journey, the course of which climate researchers can accurately predict.

In the first quantitative analysis of deep-sea bioluminescence, researchers show that three quarters of the animals in Monterey Bay from the surface down to 4,000 meters deep can produce their own light.

New research has looked to the distant past -- all the way back to Earth's earliest oceans. A newly developed model suggests that the early oceans, right around the time that life originated, were somewhat acidic, and that they gradually became alkaline.
