Warm winds: New insight into what weakens Antarctic ice shelves
New research describes for the first time the role that warm, dry winds play in influencing the behavior of Antarctic ice shelves.

Predicting the movement, impacts of microplastic pollution
Microplastics, which are particles measuring less than 5 mm, are of increasing concern. They not only become more relevant as other plastic marine litter breaks down into tiny particles, they also interact with species in a range of marine habitats. A new study takes a look at how global climate change and the impact of changing ocean circulation affects the distribution of marine microplastic litter.

Global warming making oceans more toxic
Climate change is predicted to cause a series of maladies for world oceans including heating up, acidification, and the loss of oxygen. A newly published study demonstrates that one ocean consequence of climate change that has already occurred is the spread and intensification of toxic algae.

Climate change clues revealed by ice sheet collapse
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.

Forces that threaten sensitive coastlines
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, much of it caused by waves that eroded away the edges of the pond.

Rising water temperatures endanger health of coastal ecosystems, study finds
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 formation of gold deposits in South Africa
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 hydrothermal fluids played a major role.

Coral reefs struggle to keep up with rising seas, leave coastal communities at risk
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, coastal communities protected by the reefs are facing increased risks from storms, waves and erosion.

Canary in the kelp forest: Sea creature dissolves in today's warming, acidic waters
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.

Water is streaming across Antarctica
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.

In new paper, scientists explain climate change using before/after photographic evidence
A group of scientists offers photographic proof of climate change using images of retreating glaciers.

Arctic river ice deposits rapidly disappearing
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.

Migration from sea-level rise could reshape cities inland
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.

Models, observations not so far apart on planet's response to greenhouse gas emissions
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.

Glacier shape influences susceptibility to thinning
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 during the next century, a number that currently ranges from inches to feet.

Methane seeps in the Canadian high Arctic
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, discovered an astounding number of methane seep mounds in Cretaceous age sediments.

With magnetic map, young eels catch a 'free ride' to Europe
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, beginning the cycle again. Now, researchers have gained new insight into how the young eels make such a remarkable journey.

New study emphasizes the relative scarcity of lake water
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 understanding of climate change and the carbon cycle.
