The United States Navy is drawing up a plan to operate in what is rapidly becoming a seasonally-open Arctic Ocean, and thus a new theater of operations. The amount of sea ice that covers the Arctic Ocean at the end of melt season in September has receded by about 3% per decade since 1981, with a record low set in 2012. Show More Summary
For our second Science Graphic of the Week, we bring you some beautiful views of some bad news. The images in the gallery above show how pulses of warm water, dumped into chilly Arctic seas by rivers crossing continents, are...
The heat from warm river waters draining into the Arctic Ocean is contributing to the melting of Arctic sea ice each summer, a new NASA study finds.
The melt season across the Arctic is getting longer by five days per decade, according to new research from a team including Prof Julienne Stroeve (Professor of Polar Observation and Modelling at UCL Earth Sciences). read more
The ice-free season across the Arctic is getting longer by five days per decade, according to new research from a team including Prof Julienne Stroeve (UCL Earth Sciences). New analysis of satellite data shows the Arctic Ocean absorbing ever more of the sun's energy in summer, leading to an ever later appearance of sea ice in the autumn. Show More Summary
No mention though of the possibility that this is all part of a natural pattern, and of course no mention of Ms. Stroeve’s Greenpeace connections to her research, which bring her scientific objectivity into question. From NSIDC and UCL: New … Continue reading ?
Thicker, older ice has declined dramatically as Arctic climate changes
Antarctica's Ross Sea is one of the few polar regions where summer sea-ice coverage has increased during the last few decades, bucking a global trend of drastic declines in summer sea ice across the Arctic Ocean and in two adjacent embayments of the Southern Ocean around Antarctica. read more
(By Jacob Chamberlain) One of nature's key defenses against global warming—the reflection of the sun's rays away from Earth by Arctic sea ice—has fallen victim to… global warming. And according to a…
Scientists have long modeled the expected warming due to the decreased albedo effect as melting Arctic sea ice exposes more open ocean. As early as the 1960?s climate researchers have predicted how this phenomenon will amplify global warming. read more
The Arctic's "old ice" -- ice that had been around for at least 4 years -- used to make up about a quarter of all the ice in the Arctic sea.
From the beginning of February through Monday, Arctic temperatures were between 7.2°-14.4°F above normal. The post Even In Perpetual Darkness, Arctic Sea Ice Coverage Drops To Record Lows appeared first on ThinkProgress.
The retreat of sea ice in the Arctic Ocean is diminishing Earth's albedo, or reflectivity, by an amount considerably larger than previously estimated, according to a new study that uses data from instruments that fly aboard several NASA satellites.
Less Arctic sea ice means a warmer Arctic, which means less Arctic sea ice, which mean an even warmer Arctic... The post Melting Ice Makes The Artic A Much Worse Heat-Magnet Than Scientists Feared appeared first on ThinkProgress.
Guest Post by Willis Eschenbach There’s a new study in PNAS, entitled “Observational determination of albedo decrease caused by vanishing Arctic sea ice” by Pistone et al. Let me start by registering a huge protest against the title. The sea … Continue reading ?
If you think the weather has been weird, the Arctic sea ice loss astounding, and the accelerating Greenland ice sheet loss worrisome with the modest Arctic warming we've had to date, well, buckle up, we're in for a bumpy century. The post Arctic Autumns On Track To Warm A Staggering 23°F, NOAA Warns appeared first on ThinkProgress.
As the Arctic continues to see dramatic declines in seasonal sea ice, warming temperatures and increased storminess, the responses of marine mammals can provide clues to how the ecosystem is responding to these physical drivers. Seals,...Show More Summary
Recently, surface temperatures haven't appear to warm as fast as expected — although the oceans have, while Arctic sea ice, Greenland and Antarctica have melted faster than expected. New research finds the slowdown is due to anomalously fast trade winds. Show More Summary
Measurements from ESA’s CryoSat satellite show that the volume of Arctic sea ice has significantly increased this past autumn. The volume of ice measured this autumn is about 50% higher compared to last year. In October 2013, CryoSat measured about … Continue reading ?
Antifreeze proteins from fish living in icy seas have inspired a new way to freeze blood which could one day increase the precious stocks available for medical procedures.
