5 Potential Changes in: Temperature Sea level Sea ice extent Salinity CO2 concentrations and ph Rainfall patterns Storm frequency, wind speed and wave conditions Climate patterns

6 Temperature Figure 1-3. Contribution of Working Group I to the Fourth Assessment Report of the Intergovernmental Panel on Climate Change, 2007

7 Rising Sea Levels Contribution of mountain and subpolar glaciers to sea level. Shown are sea level change (mm/year, red) and sea level rise (mm, blue). [From M. Dyurgerov, INSTARR, University of Colorado]

10 Ice cover Figure Multi model mean sea ice concentration (%) for January to March (JFM) and June to September (JAS), in the Arctic (top) and Antarctic (bottom) for the periods (a) 1980 to 2000 and b) 2080 to 2100 for the SRES A1B scenario. The dashed white line indicates the present day 15% average sea ice concentration limit. Modified from Flato et al. (2004).

16 Poll Question How will marine mammals be affected? A) Prey B) Distribution, Migration C) Habitat D) Reproductive success E) All of the Above

17 So, how will marine mammals be affected? Direct Habitat Temperature Indirect effects Prey Distribution, Migration Community Structure Reproductive success Disease NOAA Photo Library Type B pack ice killer whale from the Antarctic. Bob Pitman, NOAA Southwest Fisheries Science Center

18 Examples for: Temperature Sea level Sea ice extent Salinity CO2 concentrations and ph Rainfall patterns Storm frequency, wind speed and wave conditions Climate patterns

19 Responses to climate change Move move to a different area to track environmental changes Change stay in same place, but change to match environment change prey, change reproductive timing, migratory timing etc. Extinction
