Greenhouse effect — Arctic warming

Is a greenhouse effect a theory or a fact?

Greenhouse effect — Arctic warming

Greenhouse effect — Arctic warming

Perhaps a few of the “climate change scientists” in the Cowichan Valley area can provide answers to the following questions relating to a “greenhouse effect”.

Is a greenhouse effect a theory or a fact?

If it is a fact, is it a global effect, or a localized effect?

If it a global effect, why is the Canadian Arctic warming at twice the rate of the rest of Canada?

(Should be warming at the same rate.)

If it is a local effect, same question, why is the Arctic warming at twice the rate of the rest of Canada? (The fact is, the Arctic is “sparsely” populated, with very little industry to give off any significant amount of greenhouse gas emissions.)

If the warming of the Arctic is not due to a greenhouse effect, why should we not consider the warming as a “normal” sun radiation effect?
