Minnesota natural history: Pretty good, not bad, or just different?  .

North America's three largest biomes meet in Minnesota. The north woods of the boreal zone, the prairies of the west, and the eastern deciduous forests intersect here. Our mid-continental location has a climate of extremes- hot summers bringing humidity from the gulf and legendary winters of arctic temperatures. The southern, eastern and western boundaries of Minnesota biomes reflect these extremes and are already responding to the effects of greenhouse gas emissions on climate. Change is perhaps more evident here than in many places.   But drama isn't new to Minnesota. Glacial cycles, ancient seas, a mid-continental rift with massive lava flows, a fossil record of how early photosynthesis changed Earth's atmosphere, and the oldest rock exposures in North America. It's all right here in fly-over country. How plants responded to these events offer deep lessons from the past and hope for the future.
