4. Severe coastal erosion will be a growing problem as rising sea levels and a reduction in sea ice allow higher waves and storm surges to reach shore. Along some Arctic coastlines, thawing permafrost weakens coastal lands, adding to their vulnerability. The risk of flooding in coastal wetlands is projected to increase, with impacts on society and natural ecosystems. In some cases, communities and industrial facilities in coastal zones are already threatened or being forced to relocate, while others face increasing risks and costs.

11. Transportation and industry on land, including oil and gas extraction and forestry, will increasingly be disrupted by the shortening of the periods during which ice roads and tundra are frozen sufficiently to permit travel. As frozen ground thaws, many existing buildings, roads, pipelines, airports, and industrial facilities are likely to be destabilized, requiring substantial rebuilding, maintenance, and investment. Future development will require new design elements to account for ongoing warming that will add to construction and maintenance costs. Permafrost degradation will also impact natural ecosystems through collapsing of the ground surface, draining of lakes, wetland development, and toppling of trees in susceptible areas.

14. Impacts are Local: While IPCC and climate and global change research, during the past 10- 20 years, have substantially enhanced and deepened our knowledge of the global means and large-scale trends of climate change and is consequences, the reality is that now we must extend that knowledge to the regional or more local scales where the “patchiness”, extremes, and “surprises” are most likely to be expressed. This is where residents, stakeholders, and governments “see” the consequences of climate variability and change.

15. International Polar Year (2007-09) Drivers include: Growing need to understand change in the polar regions Anniversary of past IPYs and IGY provides impetus New advances in technology and logistics provide ways to address new issues and access new areas

16. ICSU IPY Themes 1. Determine environmental status of polar regions by quantifying spatial and temporal variability. 2. Quantify past and present environmental and human change in the polar regions 3. Advance understanding of polar - global teleconnections on all scales and processes controlling these interactions 4. Investigate the unknowns at the frontiers of science in the polar regions. 5. Use the unique vantage point of the polar regions to develop and enhance observations on Earth and beyond (Earth's inner core, magnetic field, the Sun and beyond. 6. Investigate cultural, historical, and social processes that shape the resilience and sustainability of circumpolar human societies and identify their contributions to global cultural diversity and citizenship.

17. ICSU Observational Initiatives 1.Produce synoptic set of multidisciplinary observations to establish the status of the polar environment in 2007-2009 2. Acquire key data sets necessary to understand factors controlling change in the polar environment 3.Establish a legacy of multidisciplinary observational networks 4.Serve as launch of internationally coordinated, multidisciplinary expeditions into new scientific frontiers 5. Help implement polar observatories to study important facets of Planet Earth and beyond 6. Create datasets on the changing conditions of circumpolar human societies from the First IPY 1882-83 to the present
