Geese and People
Geese are important food for people.
These plastic enclosures are designed to warm the ground 2º.
Through this study, we are learning more about variables that affect plant growth, nutrient cycles and the use of carbon dioxide by saltwater tundra plants.
These chambers increase the temperature of the soil and plants on the delta by ~ 2º C. What will happen to the plants if the atmosphere warms by 2º. The mean annual surface temperature change in Alaska from 1994 to 2007 has been 3.4º F (www.fws.gov/alaska/climate/inak.htm)
Scientist at work
These scientists are first trying to understand what would happen to the plants that geese eat if the climate continues to increase.
