Reducing it will result in the same climate conditions we saw before it's introduction. Not exactly difficult to comprehend.
Climate isn't static. Never has been. We could reduce our emissions to zero and the climate on this planet will still change.
'Changing' isn't the problem. It's the rate of change. That is unprecedented in the 800,000 year record of temperatures that we have.
The problem is that many species, including our own, can't adapt that quickly to the new biosphere.

Climate models have been correctly predicting climate for 60 years now. Reducing greenhouse gasses to the same levels Y years ago should result in the same climate we saw Y years ago.
Or am I off base?
Now, think of it the other way. Climate models are predicting some pretty drastic weather over the coming century. Which is cheaper, a carbon tax now, or all that damage for all that time?
You're off base.
You're ignoring the natural change within the Earth during that time period. These changes or events will happen on Earth whether we are here or not. Are we pushing the timeline closer? Yes.
No, they will not occur if we are not here. As pointed out, the rate of change of atmospheric CO2 is never seen before, except in the extreme events such as a volcanic eruption. And even then, not at this rate of change, and the evidence is directly related to burning fossil fuel.
Nothing else on Earth burns fossil fuel.

How much closer? We don't know.
Yes, we do. And we also know that by the time we have enough data to say statistically "for sure" that we are the cause of global warming, it will already mean that parts of the Earth will be uninhabitable and many species will already be gone. It's that pesky 'rate of change' again.

How much more time can we buy by doing these changes? We don't know.
Yes, we do. How bad its going to be and how soon is the only debate left. Starting earlier means less cost later. We were told that Hurricane Katrina was just the start of things to come. Then Hurricane Sandy pummelled New York, and there were more warnings. Then Hurricane Harvey set a new standard for destruction, and highlighted exactly what was predicted for Hurricane development affected by global warming.
It wasn't just a powerful storm, it was also met with totally calm upper winds that let it dump it's full force on Houston for days, instead of the upper winds moving it along.

A carbon tax in Canada will have zero effect on climate change on Earth. It's not needed.
We've already proved this repeatedly as we've advanced so far as a Country without a carbon tax. The massive amount of energy reduction. The removal of certain chemicals that damaged the ozone. All of this stuff was done without a carbon tax.
We can still 'do out part' without a carbon tax.
Given the level of denial around here, show me the political will to change without being forced to change. Humans are a fickle creature. We don't plan well for the future longer than a season, we don't like the uncertainty required in planning for things on a global environmental scale, and we don't like to do something if it's going to cost us.
Well, we've been dumping toxins and pollutants into our environment for a couple generations because we thought it had no effect, and now the bill is coming due. Time to pay the cheque.
