DEPLETION OFSUMMER SEA ICE Observed sea ice September 2003 Observed sea ice September 1979 These two images, constructed from satellite data, compare arctic sea ice concentrations in September of 1979 and 2003. September is the month in which sea ice is at its yearly minimum and 1979 marks the first year that data of this kind became available in meaningful form. The lowest concentration of sea ice on record was in September 2002. Source: ACIA, Impacts of a Warming Arctic, Climate Impact Assessment Report, Cambridge University Press, 2004
GREENLAND ICE SHEET MELT EXTENT Seasonal surface melt extent on the Greenland Ice Sheet has been observed by satellite since 1979 and shows an increasing trend. The melt zone, where summer warmth turns snow and ice around the edges of the ice sheet into slush and ponds of meltwater, has been expanding inland and to record high elevations in recent years. When the meltwater seeps down through cracks in the ice sheet, it may accelerate melting and, in some areas, allow the ice to slide more easily over the bedrock below, speeding its movement to the sea. In addition to contributing to global sea-level rise, this process adds freshwater to the ocean, with potential impacts on ocean circulation and thus regional climate.

We need to focus on local andregional needs/resources. -What are our Greenhouse Gas Emissions?
Our emissions choices affect future NE climate Pie chart source: Energy Information Administration (EIA), State Energy Related Carbon Dioxide Emissions by Fuel (2001).
We need to focus on local and regional needs/resources. -Where does our energy come from and what does it cost?
The High Cost of Importing Carbon Wholesale Fossil Fuel Expenditures – New England Fossil Fuel Expenditures in 2004 = $21 Billion Only 16% for Electric Generation (Public School Expenditures FY2004 = $23.6 Billion)
We need to focus on local andregional needs/resources. -Where does our food come from?
Postponed action is no longer an option… • We have greatly exceeded the resources available to us. • The time to consider our footprint and focus on local solutions is now. • UK 12 acres • US 24 acres • Ecovillage 6 acres
