  1. SEARCH Study of Environmental ARctic CHange

  2. Winter Europe Temperatures Spring Alaska Temperature Permafrost temperature Barents Sea Cod Growing Seasons Greenland Shrimp Atlantic Water in Arctic N. American Caribou Arctic Sea Level Pressure Norway Deer Stratosphere Temperature Marine mammals Sea Ice Area Snow Area Tundra Area Arctic Changes Over the Past 35 Years

  3. PC1 Correlation Magnitudes Principal Component/EOF AnalysisMode 1 Regime-like 86 time series Climate Indices Atmosphere Ocean Sea Ice Terrestrial Biology Fisheries

  4. High latitudes are sensitive to changes in atmospheric and oceanic circulation Temperature anomalies for NH winter following the eruption averaged for all six volcanoes with ENSO signal removed. Light shaded areas with anomalies <-0.25C, Dark shaded areas with anomalies >+0.25C. Robock & Mao, 1995, J Climate

  5. Zonal mean Surface Air Temperature anomalies Wintertime (Nov – Apr) Semenov et al,2003

  6. 2000 1980 1960 1940 1920 1900 1880 1860 Surface Air Temperature Anomalies (April)

  7. 2000 1980 1960 1940 1920 1900 1880 1860 Surface Air Temperature Anomalies (January)

  8. Feedbacks are important The lost tundra areas between 1978 and 1998 The change in NDVI from 1980s to 90s Photos from the Ayiyak River (Alaska) show an increase in shrubs.Sturm et al., 2001, Nature

  9. THEMES This is an Open Science Meeting • Change and Impacts Monday • Feedbacks Tuesday • Connection with Global Climate Wedensday
