One of the things climate change science deniers say, to throw you off, is that Antarctic sea ice is expanding. They even claim that the amount of expansion of Antarctic sea ice offsets the dramatic retreat of Arctic sea ice (see this for the latest on the Arctic). I’ve even seen it argued, in that…
As it does every summer, the Arctic Sea ice is melting off. Over the last several years, the amount of sea ice that melts by the time it hits minimum in September has generally been increasing. So, how’s it doing now? The graph above shows the 1981-2010 average plus or minus two standard deviations. Before…
By Tim Radford, Climate News Network A sophisticated array of automatic sensors will allow scientists to conduct the longest ever monitoring programme to determine the precise physics of summer sea ice melt in the Arctic.
An international team has placed sensors on and under Arctic sea ice to monitor this season's retreat. Scientists hope to understand the physics of the ice edge in order to predict summer conditions in the Arctic Ocean.
As sea ice begins to melt back toward its late September minimum, it is being watched as never before. Scientists have put sensors on and under ice in the Beaufort Sea for an unprecedented campaign to monitor the summer melt. The international effort hopes to figure out the physics of the ice edge in order to better understand and predict open water in Arctic seas. read more
Great news for seals! For caribou, not so much.
Arctic Ocean sea ice. (Photo: NASA Goddard Space Flight Center / Flickr Creative Commons) - A new analysis focusing on sea level rise found that coastal flooding has dramatically increased in frequency along the Eastern Seaboard in recent years. The analysis found that flood levels met or exceeded NOAA’s flood thresholds more than 20 days a year in six coastal cities. Reuters
Sea ice in summer looks dramatically different than sea ice in winter, even in the polar Arctic. Summer snowmelt, pools of water on thinning ice and exposed ocean replace vast winter expanses of white snow-covered ice -- and this weekend NASA's high-flying laser altimeter begins a campaign to investigate these features.
Rising global temperatures are melting Arctic sea ice, so much so that some companies are now viewing the Arctic Ocean as a major shipping route for energy supplies.
This month’s open thread. Topics of potential interest: The successful OCO-2 launch, continuing likelihood of an El Niño event this fall, predictions of the September Arctic sea ice minimum, Antarctic sea ice excursions, stochastic elements in climate models etc. Just for a change, no discussion of mitigation efforts please!
National Geographic is making a major change to its next atlas: National Geographic’s mapmakers drew their new rendition based on how the Arctic looked in 2012, using sea ice data collected by NASA and NSIDC. While the amount of Arctic ice grows and shrinks throughout the year depending on the season, the Atlas depicts multiyear ice — ice that’s older than an […]
Filmmaker Adam Ravetch was able to capture stunning video of polar bears searching for sea ice using a GoPro camera, and he is using it to highlight the challenges the arctic predators face as climate change radically alters the landscape in which they evolved. Ravetch, an award-winning cinematographer who heads Arctic Bear Productions, captured the
A smaller Arctic ice shelf is the biggest change National Geographic cartographers have made since they had to divvy up the U.S.S.R.
National Geographic's latest global atlas reveals how Arctic ice is disappearing. National Geographic comes out with a new world atlas about twice a decade, as mapmakers struggle to stay up to date with things like shifting political borders and ballooning populations. Show More Summary

For the first time in roughly 2 million years, melting Arctic sea ice is connecting the north Pacific and north Atlantic oceans. The newly opened passages leave
Warmer Atlantic water has caused a retreat of the ice edge north of Svalbard during the last decades, researchers report. In contrast to other areas of the Arctic Ocean, the largest ice loss north of Svalbard occurred during winter. The Arctic sea ice area has been measured, using satellites, since 1979.
A new digital resource brings together centuries of cultural knowledge for the first time, showing that networks of trails over snow and sea ice, seemingly unconnected to the untrained eye, in fact span a continent – and that the Inuit have long-occupied one of the most resource-rich and contested areas on the planet.
The U.S. Geological Survey (USGS) on Friday released the first-ever video shot from the perspective of a polar bear on Arctic sea ice. The video, which was recorded using a video collar device, shows a bear walking on sea ice, swimming, attempting to eat a frozen seal and playing with a potential mate. Show More Summary
At least, we all live with the Arctic, since what happens in the Arctic – and the Antarctic – affects every other part of the globe, and vice versa. Melting sea ice brings changing weather patterns; ocean temperatures and currents are shifting, with fish and other sea life following them, changing the availability of food […]
