The climate is always changing but is doing so more rapidly because of carbon dioxide emissions being spewed into the atmosphere. That message was delivered to a Senate committee examining the effects of climate change on agriculture and forestry.
University of Guelph, Ontario Professor Emeritus Barry Smit says there's a misconception about the tipping point with climate change. He points out the change is gradual, not sudden.
The Senate committee heard from farmers more concerned about a carbon tax than climate change. That doesn't surprise Smit who says most people associate climate change with higher temperatures but don't make the connection with extended periods of dought.
Senators were told were it not for climate change, we would be in a period of cooling.
Smit says farmers adapt to climate change by switching to different crops and that's why you now see corn being grown in Atlantic Canada.
