Thank-you to everyone who was involved with launch events, who launched virtual balloons, who launched real balloons (see the Swedish launch web-cast!), those behind the scenes, and those on stage. IPY Celebrations around the world on March 1st, and throughout this week, have been a huge success. You can watch those you missed on the Arctic Portal, or still launch your virtual balloon now, and throughout IPY, to recognise the importance of the polar regions to the whole planet. Here is a map showing balloons that have been launched around the world (you can zoom in on where you live or zoom out to see the world map!): ...

IPY launch events around the world can be viewed live at the Arctic Portal. We also encourage everyone to launch a virtual balloon and show how many people around the world care about the polar regions and are interested in IPY. Everyone is welcome to join in, young or old, polar or tropical! The Official Opening Ceremony takes place in Paris at 11am local time. That is UTC 10:00, or, 1am in Anchorage, 5am in New York, 7am in Santiago, 3.30pm in Calcutta, 7pm in Tokyo, and 9pm in Sydney. You can watch it live or after the event on the web at the Arctic Portal, where you will also find webcasts of other national launch events from around th...

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...

Cape Farewell brings artists, scientists and educators together to bring about long-term change in cultural attitudes towards climate change. Created by artist David Buckland in 2001, Cape Farewell has lead three expeditions to the High Arctic, the frontline of climate change. From these expeditions has sprung an extraordinary body of artwork, a film co-produced by the BBC, Cape Farewell’s first major book title, The CD ARCTIC by Max Eastley, educational resources for GCSE Geography and Science and a UN award winning website. The project is widely acknowledged to be the most significant sustained artistic response to climate change anywhere in the world.

The 2007-2008 International Polar Year (IPY) provides an international framework for improving our understanding of high-latitude climate change and enhancing our skill in predicting world-wide impacts. Recent, well documented observations of the dramatically changing high-latitude components of earth’s cryosphere (e.g., those areas where water is frozen either seasonally or permanently) make IPY science investigations particularly timely and relevant to scientists, policy makers and the general public. Effective IPY investigations require a range of commitments of resources: from providing support to individual field activities, to those which require the international coordination of complex systems and their operations. During IPY, to date considerable progress is being made towards characterisation of key high-latitude processes by means of spaceborne snapshots of the polar regions. A number of ongoing efforts are described below which are designed to coordinate these satellite acquisitions, to help demonstrate the benefits of a cryospheric observing system component, and to develop IPY data legacy comprising critical climate benchmarks.

During the IPY, the USGS will highlight numerous long-term studies of the polar regions on the state of the cryosphere (glaciers, permafrost, sea ice), the impacts of change over the last few decades, the petroleum resource potential of the Arctic, and the consequences of permafrost thawing on the Yukon River watershed in Alaska and Canada. Also, we will produce a high resolution Landsat mosaic image of Antarctica.

Thermal State of Permafrost Permafrost conditions underlie upwards of 25% of the Earth's land surface. Permafrost temperatures are a function of past and present climates and vary greatly depending on location. Lacking is a comprehensive set of pemafrost measurements against which to assess present and future regional and global changes. Duirng IPY, TSP researchers will obtain a "snapshot" of permafrost temperatures in hundread of borehole throughout the world.

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.

This project – which involves scientists from two dozen countries – will examine how atmospheric processes in the Southern Hemisphere affect current climate, and provide an important baseline for assessing future climate change. COMPASS will obtain the first circumpolar snapshot of the Southern Hemisphere atmospheric environment – covering physical, chemical and ecological properties – a major observational milestone. Only by harnessing the resources of the global polar community can this multinational project achieve the depth of investigation required to improve knowledge of future climate change and its impacts.
