What moves the bulk of the heat from the equator to the poles where it is radiated is sea water. That flow is damaged or shut down by the addition of fresh water into the sea near the poles by ice melting at the poles.
This is a fact. What is coming and soon is cooling.
Fact 1: We're dumping huge amounts of CO2 into the atmosphere by burning fossil fuels. That's not up for debate.
Fact 2: It's well know that CO2 is a major greenhouse gas. In fact, if we didn't have CO2 in the atmosphere, the earth would be much colder. Adding CO2 to the atmosphere will increase the earth's average temperature. None of that is up for debate.
Fact 3: The earth's temperature has been steadily rising. It's been measured on land, at sea, and from space. Arctic sea ice is melting rapidly, and ocean temperatures are increasing. None of that is up for debate either.
The conclusion seems rather obvious, doesn't it? Burning fossil fuels is increasing the earth's temperature. We probably shouldn't keep doing this long term, since we only have one atmosphere. If we screw up the climate, we don't have a back-up planet to move to.
Nobody is suggesting that we shut down the global economy. But it would seem prudent to find other ways of getting economical energy that doesn't involve burning fossil fuels. Or if that is not possible, find a way to capture the CO2 instead of dumping it into the atmosphere.
I don't understand why this is a Left vs. Right issue. Quite a bit of the USA's agricultural production is in climate-sensitive areas like the Great Plains and California. Do we Good God Fearin' Amurricans really want secular Canada and Russia becoming the bread baskets and super powers of the world, with the USA becoming a food-poor third-world country like Mexico?
Reminds me of the false conclusion. Example= since most people who smoke used to chew gum, the theory was that gum chewing led to smoking. Another example= since most people who use heroin smoked pot at one time, then pot smoking leads to heroin use. Both were considered as true at one time, but are now known to be false.
The logic is valid but the premises are false.

Why is ice melting, on average, at the poles? That should not be happening (other than from seasonal cycles) if the earth is not warming.

That's a false analogy.
It's well known that CO2 is a greenhouse gas. If CO2 (and other greenhouse gasses like methane) were not present, the earth would be much colder than it is now; possibly too cold to support life.
Increasing the amount of greenhouse gasses will increase the average temperature. And we're doing just that, by burning through fossil fuels at a very rapid rate.
Why do you say that those premises are false? Can you link to a peer reviewed scientific journal article that states why most scientists working in the field are wrong?
The AGW crowd insists that the AGW theory is absolute. The big bang theory has learned scientists that disagree and they are not called crackpots. The theory that a meteor destroyed the dinosaurs has paleontologists who don't agree with it and they are not called crackpots. But let any scientist disagree with AGW and they are called crackpots. Makes no sense.

That human activities emit CO2, no, that is not up for debate, we also exhale huge amounts of CO2 too.
Humans are responsible for about 3% of that 0.04%, in the atmosphere. The natural production of CO2 by plants, animals and bodies of water and geological functions on planet earth make up the other 97% of CO2.

CO2 is a minor trace gas. Water vapor and methane are much stronger greenhouse gases than CO2.

Have you seen the climate record? The planet just came out of a little ice-age, of course it warmed up, otherwise we'd still be in the LIA. Would you prefer that we had never warmed up, and remained in a cool period?
BTW, we are living in a cool period, by comparison to the last 10,000 year averages.

You know what else came online about the same time as the industrial revolution? Radio frequency radio and TV? We have so much RF in the air now, from radio, TV, cell phone towers, satellites, WiFi... so maybe all that RF is cooking the molecules in our atmosphere.
There, that's my new theory, so ban cell phones, TV and radio.
