Last January, a study in Nature Climate Change showed the world's glaciers are the smallest they've been in human history, revealing radiocarbon material that hasn't been exposed for 40,000 years. Now, new research published in Nature quantifies how much the world's lost glaciers have contributed to rising sea levels. From …
Some 80 percent of Arctic ice may disappear in 30 years, not 90 as scientists had previously estimated, according to a new study on the impact of global warming. "The amount of the Arctic Ocean covered by ice at the end of summer by then could be only about 1 …
PARIS: Updating the waterwheel to generate electricity and compete with solar and wind As sources of green power go, generating electricity from hydropower, using a creek or stream on your local property, has a lot to recommend it. Provided you have a stream, that is, and it flows fast and …
The asynchronous relationship between millennial-scale temperature changes over Greenland and Antarctica during the last glacial period has led to the notion of a bipolar seesaw which acts to redistribute heat depending on the state of meridional overturning circulation within the Atlantic Ocean. Here we present new records from the South …
Sailors, fishermen and cruise passengers should be on the alert. If anybody spots a yellow rubber duck bobbing on the ocean waves, NASA would like to know. The U.S. space agency has yet to find any trace of 90 bathtub toys that were dropped through holes in Greenland
WASHINGTON: More than two trillion tonnes of land ice in Greenland, Antarctica and Alaska have melted since 2003, according to new NASA satellite data that show the latest signs of what scientists say is global warming. More than half of the loss of landlocked ice in the past five years …
Reconstructions of ancient atmospheric carbon dioxide (CO2) variations help us better understand how the global carbon cycle and climate are linked. We compared CO2 variations on millennial time scales between 20,000 and 90,000 years ago with an Antarctic temperature proxy and records of abrupt climate change in the Northern Hemisphere. …
Two new studies point to random, wind-induced circulation changes in the ocean--not global warming--as the dominant cause of the recent ice losses through the glaciers draining both the Greenland and West Antarctic ice sheets.
By Deborah Zabarenko, Environment Correspondent WASHINGTON (Reuters) - To help figure out what's happening inside the fastest-moving Greenland glacier, a U.S. rocket scientist sent 90 rubber ducks into the ice, hoping someone finds them if they emerge in Baffin Bay. The common yellow plastic bath toys are one part of …
How fast will our coastlines be swallowed up by rising sea levels? This week, an ice-age glacier lent support to the controversial view that sea levels could rise by 1 metre per century - and so drown land now occupied by 145 million people by 2100. To get a better …
It is thought, that the Northern Hemisphere experienced only ephemeral glaciations from the Late Eocene to the Early Pliocene epochs (about 38 to 4 million years ago), and that the onset of extensive glaciations did not occur until about 3 million years ago. Several hypotheses have been proposed to explain …
To understand what has happened to the earth's atmosphere--and, therefore, how our climate might change in the future--some ice-core scientists in the Arctic are training their eyes directly downward. It's an incredibly important job. It's also, as the participants in the North Greenland Eemian Ice Drilling (NEEM) project will attest, …
As the world heats up, the sea levels are rising. Many experts warn that dramatic sea-level rise is global warming's biggest danger. Two main factors are behind this: thermal expansion of the ocean and melting Ice. First, as the ocean gets wanner from global warming, its volume expands. This is …
The meltdown in the Arctic is speeding up and as a result the North Pole could be ice-free by 2013 instead of in 60 years' time as earlier predicted, scientists have warned. Their apprehensions are based on computer studies of satellite images that reveal that ice at North Pole melted …
Rivers of melting ice form on the Sermeq Kujalleq Glacier in Ilulissat, Greenland, pictured in October 2007 You can't see climate change in action, much to the disappointment of photographers and magazine art directors. Warming is a function of time, and we see it only as time passes. Years go …
By THOMAS L. FRIEDMAN Sometimes you just wish you were a photographer. I simply do not have the words to describe the awesome majesty of Greenland's Kangia Glacier, shedding massive icebergs the size of skyscrapers and slowly pushing them down the Ilulissat Fjord until they crash into the ocean off …
By Thomas L. Friedman Jorgen Peder Steffensen made me an offer I couldn't refuse: "If you come to Copenhagen, I will show you a real Christmas snow, the snow that fell between 1 BC and 1 AD." Now that's an offer you don't get every day! But then I don't …
