  1. The Science of Global Climate Change: How Climate Change May Affect Minnesota’s Ecosystems Dr. Jeffrey R. Corney, Managing Director of the University of Minnesota’s Cedar Creek Ecosystem Science Reserve

  2. What May Happen to Minnesota’s Climate? How May Changes in Climate Affect Minnesota’s Ecosystems?

  3. Welcome to Lake Superior?

  4. It’s All About the Climate… CLIMATE is the prevailing weather conditions of a region averaged over long periods of time. Wikipedia

  5. …and the Biomes that Result North America’s Biomes A BIOME is a large land area characterized by a prevailing CLIMATE that supports a major ecological community type. Wikipedia

  6. Minnesota’s Biomes MN DNR Minnesota is unique in that it supports three major biomes, making it a grand ECOTONE… a transition zone between biomes.

  7. Where Goes the Climate, so Goes the Biomes…

  8. Temperature (Solar Radiation) Precipitation (Amount & Timing) Soil Moisture (Evapotranspiration)

  9. Pearson Education

  10. Global Biomes “Survive & Thrive”
