Document Summary
Climate change and global warming is not the same thing. Tracked pollen to see what changes happened due to temperatures. Didn"t effe(cid:272)t pollinators (cid:271)e(cid:272)ause they"re wind pollinators. Temperature increases about 0. 1 c per decade. C3 plant species grow better as co2 levels increases- cover this in mod 3. Predicted result of warming trend- more erratic weather patterns and less predictable precipitation patterns. Longer growing seasons mean a migration of plants/crops and insects associated with them as. Canada now has the temperature levels they require now. Farmers always pushing the adaptation limits of crops. Ex sweet potatoes in ontario and new brunswick. Days > 30c corresponds with the cauliflower line. P value is a probability- its significant but it doesn"t convey the relationship. Greater moisture also means more disease factor that can reduce yields.
