CAVIAR is an international and interdisciplinary project that aims to
increase understanding of how Arctic communities are affected by
climate and other changes, and to contribute to the development of
adaptive strategies and policies.

THORPEX-IPY suggests that extreme weather events in the Arctic will
become more common as the winter ice cover retreats, with potentially
severe consequences for human activity.
“It is important that we get better at forecasting these weather
phenomena, in order to prevent the loss of human lives and
environmental disasters in the future,” said Dr. Erik Kolstad, at the
Bjerknes Centre for Climate Change, who led the study.

Our second IPY project in profile today investigates the question "Are
trees invading the Arctic?"
The 'expected' answer to this question is 'Yes': but is this really
true?
It is currently too cold for trees to exist north of the present-day
treeline, so a warming climate ought to produce a northward advance of
the trees. However, nature responds in a complex manner to changing
climate or other environmental changes. IPY project PPS-Arctic
investigates this question further with circumpolar treeline research.

The State and Fate of Permafrost on a Warming Planet:
Recent observations indicate a warming of permafrost in many northern and mountain regions with resulting degradation of ice-rich and carbon- rich permafrost. Permafrost temperature has increased by 1 to 2°C in northern Russia during the last 30 to 35 years. This observed increase is very similar to what has been observed in Alaska where the detailed characteristic of the warming varies between locations, but is typically from 0.5 to 2°C

International Team Confirms an Alps-like Mountain Range Exists under the East Antarctic Ice Sheet
Flying twin-engine light aircraft the equivalent of several trips around the globe and establishing a network of seismic instruments across an area the size of Texas, a US-led international team of scientists has not only verified the existence of a mountain range that is suspected to have caused the massive East Antarctic Ice Sheet to form, but also has created a detailed picture of the rugged landscape buried under more than four kilometers (2.5 miles) of ice.
“Working cooperatively in some of the harshest conditions imaginable, all the while working in temperatures that averaged -30 Celsius, our seven-nation team has produced detailed images of last unexplored mountain range on Earth,” said Michael Studinger, the co-leader of the U.S. portion of the Antarctica’s Gamburstev Province (AGAP) project.

In the Arctic, climate change is more than just a topic of conversation: it’s a fact of life. Arctic communities have already begun to feel the impacts of climate change, both large and small. Land erosion, melting permafrost, and flooding are forcing several Alaskan villages to consider relocation. In addition, the changing climate is affecting the health of residents, both directly and indirectly.
Results from a workshop entitled "Emerging Threats and Responses of Arctic Communities to Climate Change", are presented here the Arctic Human Health Initiative, AHHI.

In a mission of unprecedented scale, scientists are covering West Antarctica with a network of sensors to monitor the interactions between the ice and the earth below — 24 hours a day, 365 days a year.
“Our preliminary results show that we can dramatically improve our estimates of whether Antarctica is gaining or losing ice,” said Terry Wilson, leader of POLENET: The Polar Earth Observing Network—www.polenet.org

For the first time, more than 1400 early career professionals from 40 different countries working in the coldest and most remote places on this planet are united in crossing national and disciplinary boundaries to help address the rapid changes occurring in the Polar Regions and how these changes are affecting the entire planet.
“Having APECS preside over [the IPY Ceremony in Geneva] signifies not only the progress of our organization, but the confidence the senior research community has in the next generation of polar researchers to carry forward the progress made during the IPY, and to lead future research in addressing the rapid changes occurring in the harsh but fragile Polar Regions,” said Dr. Jenny Baeseman, Director of APECS, the Association of Polar Early Career Scientists.

ICECAP Completes First Field Season
Researchers with the ICECAP (Investigating the Cryospheric Evolution
of the Central Antarctic Plate) project are flying an upgraded World
War II-era DC-3 aircraft with a suite of geophysical instruments to
map the thickness of the ice sheet and measure the texture,
composition, density and topography of rocks below the ice. The data
will help them model East Antarctic ice stability, forecast how the
ice might react to climate change, and show its potential impact on
global sea level.

Circumpolar Flaw Lead System Study Celebrates with IPY in Geneva
David Barber, CFLlead scientist, says: " IPY gave us this tremendous
window into climate change. What we learned about climate change was
more dramatic and immediate than we had anticipated. Now we must take
our work to the next level and understand the very strong physical
processes which are shaping the sea ice in the Arctic and to
understand how these changes are affecting northern peoples,
industrial development and the marine ecosystem.”

If the Arctic continues to warm as predicted, large changes in
vegetation will have important consequences for the status of
permafrost, depth of the thaw layer, snow patterns, hydrological
cycles, wildlife and human uses of arctic landscapes.
'Greening of the Arctic' principal investigator Donald “Skip” Walker
says,
“If you have a map of Arctic vegetation, you have a lot of information
about how the system works. Surprisingly, there are no long-term
repeated measures of biomass in the Arctic. We'll be creating a
baseline of vegetation data in a systematic way so that we can look at
change over time.”

An IPY initiative extending Antarctic helicopter support from February
into April allowed scientists to find out what happens to aquatic
ecosystems during the summer-winter transition. Their discoveries
confirm that Antarctic ecosystems are amongst the most extraordinary
on earth, and as such will always have some new way of surprising the
scientists who study them.
Dr. Ian Hawes says, "In the best traditions of IPY, a one-off
injection of support enabled us to take a substantial step forward in
understanding these
important communities. "

Today's IPY project in profile is SALE-UNITED:
Ever since subglacial lakes captured the imagination of scientists and
the public more than a decade ago, researchers have dreamed of
entering and sampling these alien environments to unlock secrets that
might guide us in the search for life elsewhere in our solar
system.Today, what once seemed to be only lofty scientific ambitions
are now closer than ever to becoming a reality.
