Looking for ways to get your local monthly meeting off dead-center, vis-à-vis environmental matters?
Looking for ways to get your co-workers, friends and neighbors thinking about life-style changes?
Just show them the images below.
The first pair: what’s happening at the Pole

The image above, generated from satellite data, shows the extent of Arctic sea ice at the end of the northern summer in 1979. The one below shows the extent of the ice twenty-six years later, at the end of the summer in 2005.

The second pair: what’s happening at home

The map above is a chart of where plants of various sorts would grow in 1990. Zone 3, at the top, would grow only plants that could survive winter cold snaps below -30° F — plants like the arborvitae, the aspen and birch, the Canadian hemlock, some of the tougher junipers, maples, oaks, pines, and spruces, and (from Siberia) the dwarf Russian almond. Zone 10, at the bottom of the map, would grow even subtropical plants that would die if the temperature ever fell below +40° F.
The map below, just recently compiled by the National Arbor Day Foundation using weather data from 5,000 stations throughout the U.S., shows where the same plants would grow in 2006:

Invite your meeting, your co-workers, your neighbors and friends to find themselves on these maps. Invite them to imagine the situations of animals and plants that need a certain sort of climate.
Ask them what they think it will be like in another sixteen years.
Please.
