New data confirms Arctic ice trends: Sea ice being lost at a rate of 5 days per decade
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 a later appearance of sea ice in the autumn. In some regions, autumn freeze-up is occurring up to 11 days per decade later than it used to. (2014-03-04)

This data set provides researchers with a reliable tool to evaluate climate change impacts. (2014-02-24)

Graduate student makes major discovery about seal evolution
Modern pinnipeds (the group that includes seals, sea lions and walruses) show a range of sexual dimorphism (large differences in size between males and females) and mating systems that span the extremes of modern mammals. This new study using the fossil record establishes that sexual dimorphism in pinnipeds, marked by harem-like behavior, arose around 27 million years ago in association with changing climatic conditions. (2014-02-19)

Increase in Arctic cyclones is linked to climate change, new study shows

Arctic biodiversity under serious threat from climate change according to new report
Climate change caused by human activities is by far the worst threat to biodiversity in the Arctic. Some of these changes are already visible. Unique and irreplaceable Arctic wildlife and landscapes are crucially at risk due to global warming caused by human activities according to the Arctic Biodiversity Assessment, a new report prepared by 253 scientists from 15 countries under the auspices of the Arctic Council. (2014-02-14)

How do polar bears stay warm? Research finds an answer in their genes
Among polar bears, only pregnant females den up for the colder months. So how do the rest survive the extreme Arctic winters? New research points to one potential answer: genetic adaptations related to production of nitric oxide, a compound cells use to help convert nutrients into energy or heat. (2014-02-10)

Ice age's arctic tundra lush with wildflowers for woolly mammoths, study finds
A recent study in the journal Nature finds that nearly 50,000 years ago during the ice age, the landscape was filled with colorful wildflowers, which helped sustain woolly mammoths and other giant grazing animals. (2014-02-07)

DNA reveals new clues: Why did mammoths die out?
Why did mammoths and other large mammals of the tundra suddenly become extinct some 10,000 years ago? It's a question that has divided scientists over the years. Now researchers from Lund University in Sweden (and 30 other research teams from 12 countries), have used new DNA technology to show that a drastic change in the dominant vegetation -- from protein-rich herbs to less nutritious grass -- could be behind their demise. (2014-02-06)

A 'smoking gun' on the Ice Age megafauna extinctions
It was climate that killed many of the large mammals after the latest Ice Age. But what more specifically was it with the climate that led to this mass extinction? The answer to this is hidden in a large number of sediment samples from around the Arctic and in the gut content from permafrozen woolly rhinos, mammoth and other extinct ice age mammals. (2014-02-05)

Largest evolutionary study of sponges sheds new light on animal evolution
To provide a wider framework for understanding the molecular complexity behind the evolution of sponges, authors Riesgo, Windsor, Farrar, Giribet, and Leys (from the University of Barcelona, University of Alberta and Harvard University), performed the largest sequencing study to date on the genes of representatives from eight sponge genera covering all four currently recognized sponge classes. (2014-02-04)

Dramatic thinning of Arctic lake ice cuts winter ice season by 24 days
Arctic lakes have been freezing up later in the year and thawing earlier, creating a winter ice season about 24 days shorter than it was in 1950, a University of Waterloo study has found. (2014-02-03)

€2M EU funding for UEA project to understand Arctic ice melt
The University of East Anglia is launching a project to predict how the Arctic will cope with global warming by constructing a sea ice chamber. The chamber will reproduce the chemical exchanges between the ocean, sea ice, snow and the atmosphere in the Arctic. The aim is to help researchers make better predictions about the effect of global warming on both the Arctic and the rest of the world. (2014-02-02)

Polar bear diet changes as sea ice melts
A series of papers recently published by scientists at the American Museum of Natural History indicates that at least some polar bears in the western Hudson Bay population are using flexible foraging strategies while on land, such as prey-switching and eating a mixed diet of plants and animals, as they survive in their rapidly changing environment. (2014-01-21)

Arctic warmth unprecedented in 44,000 years, reveals ancient moss
Using radiocarbon dating, new research in Geophysical Research Letters has calculated the age of relic moss samples that have been exposed by modern Arctic warming. Results show that temperatures in the Arctic are warmer than during any sustained period since the mosses were originally buried. (2014-01-21)

Arctic cyclones more common than previously thought
Scientists have analyzed huge troves of data synthesized at the Ohio Supercomputer Center by Ohio State's Dr. David Bromwich, and they found that from 2000 to 2010, about 1,900 cyclones churned across the top of the world each year, leaving warm water and air in their wakes -- and melting sea ice in the Arctic Ocean. That's about 40 percent more of these Arctic storms than previously thought, according to the study. (2014-01-16)

Mercury and ozone depletion events in the Arctic linked to sea-ice dynamics
This week a new study published in Nature and co-authored by Drs. Chris Moore and Daniel Obrist of Nevada's Desert Research Institute establishes, for the first time, a link between Arctic sea ice dynamics and the region's changing atmospheric chemistry potentially leading to increased amounts of mercury deposited to the Earth's northernmost and most fragile ecosystems.

Climate change threatens genetic diversity, future of world's caribou
Caribou in southern and eastern Canada may disappear from most of their current range in 60 years if climate change takes the toll on their habitat that scientists predict in a paper appearing online Dec. 15 in the journal Nature Climate Change. Scientists looked at reservoirs of genetic diversity in caribou and whether that diversity was linked to stable habitats. (2013-12-15)

Antarctic fjords are climate-sensitive hotspots of diversity in a rapidly warming region
In the first significant study of seafloor communities in the glacier-dominated fjords along the west Antarctic Peninsula, scientists expected to find an impoverished seafloor highly disturbed by glacial sedimentation, similar to what has been documented in well-studied Arctic regions. Instead, they found high levels of diversity and abundance in megafauna. The difference can be explained by the fact that the subpolar Antarctic is in an earlier stage of climate warming than the Arctic. (2013-12-03)

Arctic study shows key marine food web species at risk from increasing CO2
A research expedition to the Arctic, as part of the Catlin Arctic Survey, has revealed that tiny crustaceans, known as copepods, that live just beneath the ocean surface are likely to battle for survival if ocean acidity continues to rise. The study found that copepods that move large distances, migrating vertically across a wide range of pH conditions, have a better chance of surviving. (2013-12-02)
