Six glaciers in West Antarctica are moving faster than they did 40 years ago.

The amount of ice draining collectively from those half-dozen glaciers increased by 77 percent from 1973 to 2013, causing global sea level to rise, according to new research. 

It is said that nothing dies of old age in the ocean, that everything gets
eaten and all that remains of anything is waste.

But that waste is pure gold to
oceanographer David Siegel, director of the Earth Research Institute at U.C. Santa

In a study of the ocean's role in the global carbon cycle, Siegel and his colleagues used those nuggets to their advantage. They incorporated the lifecycle of phytoplankton
and zooplankton — small, often microscopic animals at the bottom of the food chain —into a novel mechanistic model for assessing the global ocean carbon export. 

Research using satellite observations and ice thickness measurements gathered by NASA's Operation IceBridge is giving new insight into one of the processes causing Greenland's ice sheet to lose mass.

A team of scientists calculated the rate at which ice flows through Greenland's glaciers into the ocean, which gives a clearer picture of how glacier flow affects the Greenland Ice Sheet and shows that this dynamic process is dominated by a small number of glaciers.

Operation IceBridge has been measuring the thickness of many of Greenland's glaciers, which allowed researchers to make a more accurate calculation of ice discharge rates. Researchers calculated ice discharge rates for 178 Greenland glaciers more than one kilometer (0.62 miles) wide.

Temperature has been driving the fluctuating size of Peru's Quelccaya Ice Cap, not snowfall, according to a new analysis.  The Quelccaya Ice Cap is the largest ice mass in the tropics and sits 18,000 feet above sea level in the Peruvian Andes. The dramatic shrinkage of the tropical glacier in recent decades has made it a poster child for global climate change.

The findings support suspicions that tropical glaciers are shrinking because of a warming climate, and could help scientists to better understand the natural variability of past and modern climate and to refine models that predict tropical glaciers' response to future climate change. 

Deep waters formed in the northern North Atlantic fill approximately half of the deep ocean globally.

As you might gather, that impacts the circum-Atlantic climate and regional sea levels and soaks up much of the excess atmospheric carbon dioxide from industrialization.

Changes in this circulation mode are considered by some to be a potential tipping point in future climate change that could have widespread and long-lasting impacts including on regional sea level, the intensity and pacing of Sahel droughts, and the pattern and rate of ocean acidification and CO2 sequestration. But this pattern of circulation has been relatively stable during warm climate states such as those projected for the end of the century.

Twice in recent history, the periodic El Niño event has caused sea level drops abruptly in the tropical western Pacific. The tides remain below normal for up to a year in the South Pacific, especially around Samoa, and Samoans call the resulting wet stench of coral die-offs arising from the low sea levels "taimasa" (pronounced [kai' ma'sa]).

A team of scientists at the International Pacific Research Center, University of Hawai'i at Mānoa and at the University of New South Wales, Australia is studying the climate effects of this particular variation of El Niño.  

Satellite observations of global sea-surface temperature have shown that a 30-year upward trend slowed in the last 15 years.  It can't be due to successful mitigation, since outside the United States and a few countries in Europe, CO2 emissions have not dropped back to those levels.

Some satellites carry instruments that provide a global view of the surface temperature of oceans and seas. Satellite and local readings show that sea-surface temperature rose rapidly during the 1970s and '80s but then significantly slowed in the last 15 years.

 Mesopelagic fishes like lantern fishes (Myctophidae) and cyclothonids (Gonostomatidae) live in the twilight zone of the ocean, between 200 and 1,000 meters deep.

 With a stock estimated at 1,000 million tons so far, mesopelagic fish dominate the total biomass of fish in the ocean and are the most numerous vertebrates of the biosphere. Now it turns out they have been severely underestimated. Researchers writing in Nature Communications have estimated their numbers are 10 times higher than previous estimated, based on acoustic observations conducted during the circumnavigation of the Malaspina Expedition.

It's cold and snowy just about everywhere except where you expect it. Ice in northern Alaska’s lakes during winter months is on the decline, as shown by twenty years of satellite radar imagery demonstrating how changes in our climate are affecting high-latitude environments - at least in the last few decades. 

Changes in air temperature and winter precipitation over the last five decades have affected the timing, duration and thickness of the ice cover on lakes in the Arctic. In this region, warmer climate conditions result in thinner ice cover on shallow lakes and, consequently, a smaller fraction of lakes freezing all the way through during winter months. 

Are they landing marks for aliens? Craters from World War II bombs?

The first pictures, which appeared in 2008 after being taken by a tourist, showed some strange circular formations in the shallow waters off the famous white cliffs of chalk on the island Møn in Denmark. And then they disappeared.

In 2011, the circles came back, and this time there were so many that they made it into media stories.
Since those first images appeared, people have searched for an explanation.
