Watch IPY launch events on-line at the Arctic Portal and elsewhere. Throughout this week, over twenty nations around the world are celebrating the launch of the International Polar Year 2007-2008. New Zealand, Indigenous People, Argentina, and the Ukraine have already held extremely successful events. This week, Monday will see Press and Participants gathering in London, Strasbourg, and Washington DC, and Portugal will be holding their kick-off event on Wednesday. Thursday is the big day, with the Global Launch occurring in Paris at 1000 UTC (1100 local Central European Time) and national celebrations in Australia, Brazil, Canada, China, Denmark, Greenland, Finland, France, Germany, Iceland, Italy, Japan, Norway, ...

The Permafrost Young Researchers Network (PYRN) is hosting its kick-off meeting at the Abisko Scientific Research Station, Sweden on the 22nd to 24th of February 2007. PYRN (www.pyrn.org) is an international effort under the patronage of the International Permafrost Association (IPA) to bring young permafrost researchers together during the international polar year and beyond. The first phase of the PYRN project saw more than 300 young researchers from 31 countries join the network. It rapidly became the largest young researcher-driven network in the field of cryospheric science. PYRN offers, news, information and support to its members. It has sent 17 monthly newsletters since its start in 2005, maint...

We will study the responses of the terrestrial, aquatic and glacial communities of organisms, including the microbes, at both poles to global environmental changes. Our key questions include (a) diversity and biogeography, (b) food webs and ecosystem evolution, and (c) links between biological, chemical, and physical processes in icy ecosystems. This is a huge collaboration involving 17 nations and a wide range of field work.

Integrated Data and Information Services IPY projects cover a broad range of physical, life, and social sciences. The data from these projects will be unprecedented in their breadth and diversity and will be the primary legacy of IPY. Data management is the key to preserving and building on that legacy. The IPYDIS is the responsible for managing this immense and diverse volume of data and addressing substantial challenges in the evolution of scientific values, methods, and cooperation.

ITASC is a decentralized network of individuals and organisations working collaboratively in the fields of art, engineering and science on the interdisciplinary development and deployment of renewable energy, waste recycling systems and sustainable architecture to enable the production and distribution of open-format, open-source remote field research in Antarctica and the Arctic. ITASC is a lichen-like structure sharing and integrating local knowledge, resources and skills across seven continents in order to symbiotically engage with the air, ocean, earth and space commons.

There is now clear evidence that the effects of recent and past climate changes have varied in magnitude across of the world. Some changes over periods of thousands of years seem to have affected the Arctic and Antarctic regions alternately, and this has been called the “bipolar see-saw” effect. The BIPOMAC project will collect and examine climate records in sedimentary sequences spanning the past five million years from both polar regions. These records will provide a basis for analysing the complex interactions of environmental processes that have caused the observed patterns of climate variation. Improved understanding of such processes and their interactions will increase our ability to forecast future climate and sea level change.

Global Warming will have a large impact on glaciers in the Arctic region. Sea level will be affected, and substantial changes can be expected in sediment and fresh water supplies to embayments and fjords. In GLACIODYN we study the dynamics of Arctic glaciers by means of field observations, remote sensing from satellites, and computer modelling. This will deliver tools to make more accurate predictions about future changes.

Because of their cold, dry and stable air, the polar regions are the finest locations on the planet for making frontline astronomical observations. AstroPoles is a 15-nation project to assess the astronomical conditions at four polar sites – Dome A and Dome C in Antarctica, and summit Station and Ellesmere Island in the Arctic. By measuring sky brightness, optical seeing, water vapour content and the meteorological conditions at these sites, AstroPoles will provide baseline data to assess what astronomical facilities could be built in the polar regions, and the kind of science they could tackle.

PPS Arctic: Present day processes, Past changes, and Spatiotemporal variability of biotic, abiotic and socio-environmental conditions and resource components along and across the Arctic delimitation zone. PPS Arctic investigates the causes and consequences of changes in the circumarctic treeline zone, using fieldwork and remote sensing to study and model temporal and spatial aspects of ecological, social and cultural factors. Changes in the zone affect Arctic ecosystem processes, resource availability and the entire Arctic climate through changes in tree and shrub cover and in albedo, with global consequences.
