Penguin populations in flux By Summit Voice FRISCO — Just six months after scientists documented breeding emperor penguins moving from sea ice to ice-shelf habitat, a new study reinforces the idea that Antarctica’s iconic birds may be more mobile than thought. It’s too early to say for sure, but that could be good news in … Continue reading Environment: Are Antarctica’s emperor penguins going mobile in response to global warming?

Long-term studies show potential impacts of climate change Staff Report A new set of scientific reports highlights the value of long-term observations in relatively undisturbed ecosystems and also offers a preview of how global warming may change Antarctica in coming decades. The research shows that a period of unusual warmth in 2001 and 2002, caused … Continue reading How will Antarctica respond to global warming?
Study shows growing population since end of last ice age Staff Report Global warming is expected to take a toll on some penguin populations, but other species could thrive — at least for a while. Shrinking glaciers are opening new breeding areas for Adélie penguins in East Antarctica, perpetuating a 14,000-year trend of population increases, … Continue reading Adélie penguins could be climate change ‘winners’
Genetic study tracks history of Antarctica’s emperor penguin populations Staff Report FRISCO — A genetic study shows that emperor penguins may have just barely survived the last ice age, with a few scattered populations enduring centuries of bitter cold and ice. The study covers about 30,000 years and suggests that only three populations survived, including … Continue reading Climate: Too cold for penguins?
‘If we don’t worry about the imminent threats now, it’s probably not worth worrying about the medium-term future’ By Bob Berwyn FRISCO — The world’s penguins could use a little help, a team of leading conservation biologists said last month, announcing results of a study that systematically assessed global risks to the southern hemisphere sea … Continue reading Study shows why Penguins need more protection
New study projects 50 percent decline by century’s end as sea ice habitat dwindles Staff Report FRISCO — Antarctica’s emperor penguins may be colonizing new territory right now, but the long-term outlook for the birds is grim, according to new research showing that changes in sea ice concentration will likely cause most colonies to decline … Continue reading Climate: Are emperor penguins doomed?
Collapsing icebergs could disrupt breeding and feeding By Summit Voice FRISCO — Climate change, and the the increasing frequency of unpredictable, extreme weather event, are making it difficult to project trends in penguin populations, French researchers said in a new study published this week in PLOS ONE. The authors suggest that penguins are able to … Continue reading Climate: Adélie penguins face uncertain future
Recent satellite observations show birds adapting to changes in sea ice By Bob Berwyn FRISCO — Emperor penguins living at the edge of their range may be able to find new breeding grounds as their sea-ice breeding habitat dwindles in coming decades. Recent satellite monitoring shows that the Antarctic birds moved from their traditional sea-ice … Continue reading Can emperor penguins adapt to global warming?
Plans to protect Antarctic marine biodiversity falter FRISCO — For all its reputation as an icy wasteland, Antarctica actually teams with life, which makes it all the more disappointing that an international conservation commission once again failed to finalize plans for long-sought marine protected areas in the Ross Sea and off the coast of East … Continue reading Morning photo: Antarctica wildlife
International commission to reconsider proposals for new marine protected areas in the Ross Sea and East Antarctica By Summit Voice FRISCO — For only the second time in its 32-year history, an international Antarctic conservation commission will meet outside its regularly scheduled session, and stakes are huge, as delegates from around the world will decide … Continue reading Crucial Antarctica conservation talks start next week
