You are ready now to use a climate model to find out how the surface temperature in Alaska, Northern Canada, and Greenland might change if carbon dioxide doubles over the next 100 years. The model assumes carbon dioxide concentration reaches 560 parts per million by the end of the next century.

By the way, the scales in the model show temperature in degrees Celsius (°C). To understand the conversion from Celsius (°C) to Fahrenheit (°F), use this Temperature Conversion Scale. (Page will appear in a new window)
