Thank you very much, Mr. Chair, and thank you to our witnesses for being here today.
I'd like to start with Mr. MacLean. I just have a couple of clarification questions on some of the items that were stated in the questioning. You were commenting about being able to see some of the challenges on the atmosphere. The pollution you saw in China is now coming into the north and into northern Canada.
Did I understand that correctly? Is it the same theory? Is seeing the same global warming somewhat of a Chinese phenomenon? Can you indicate how much is man-made and how much is natural, assuming the same thing?
