Video: Cycle of Severe Weather in Canada

Agricultural meteorologist Drew Lerner explains why we're getting more intense storms, wind, droughts and temperatures -- but also how Canadian ag could benefit from climate change.

Video highlights:

• CO2 concentration continues to go up, which could positively affect vegetative development
• Wind has been more intense in some Canadian regions in recent years
• Earth's global cooling phase is causing cooler cold fronts and warmer warm fronts
• Currently we've had greater contrasts in air temperatures, which can create more extreme weather
