AB: Recent studies of the arctic environment have revealed unexpected changes including lower sea-level atmospheric pressure, increased air temperature over most of the Arctic, but lower temperatures over eastern North America and Greenland, changed ocean circulation and rising coastal sea level, warmer Atlantic waters penetrating farther in the Arctic Ocean, reduced sea ice cover, and thawing permafrost. These changes are affecting every part of the arctic environment and are having repercussions on society. To understand the recent observations and put them into the context of natural variability and anthropogenic forcing, a multi-disciplinary, multi-agency program, has recently been developed. This program, SEARCH (Study of Environmental Arctic Change), has the potential to significantly contribute to the IPY by creating a framework for extensive new observations and placing the results into the context of a changing physical, biological, and social environment. Our contribution will outline SEARCH and explore its possible connectivity with the IPY.
