I have my doubts about how much of it actually is, primarily because earth has always gone through heating and cooling cycles and the data is given to us my people who primarily rely on public funding but let’s assume it is. Does putting ourselves at a competitive disadvantage to China, Russia, India countries who have no interest in cleaning up pollution make any sense? Because all that will happen is that those countries will handle all the resource extraction and manufacturing. Does having a policy of purposely bidding up energy prices make sense? Americans disproportionately have larger families, larger vehicles, larger homes, travel longer distances, rely on products that travel longer distances energy prices are highly correlated to our quality of life. There would be great political consequences for any politician who went this route.
And what scientific evidence and research do you have that shows this to be true? That is, evidence to show current warming has nothing to do with man-made emissions?
I don't doubt that man-made global warming is real. I accept the consensus among scientists who have studied the issue.
What I find dubious is the doomsday predictions that have been made. If the temperature rises, then people will turn up the AC. If sea levels rise, then people will avoid coastal dwellings and build on higher land. Stuff like that. Billions of people already live in hot, tropical countries and are fine with that.
Global warming is not going to kill off large populations of humans. People will adapt to climate change as they have for thousands of years.

There is no doubt that carbon dioxide is a greenhouse gas and increasing the amount of it in the atmosphere will increase global temperature. The bulk of the increase in global warming models is based on feedback effects of other elements besides C02, especially water vapor. Those effects are not as easy to predict, which is way the most alarmist graphs you see are always off. It is also complicating that earth's climate is known to have wildly fluctuated before humans were burning any fossil fuels. e
I support some reasonable govt regulations to protect the environment including reduced CO2. Things that are clearly overreach like banning all cars are about other political aims to limit freedom rather than help the environment.

Backwards Logic! If you are making the claim that something extraordinary is happening, the onus is on YOU to prove it.
You have to prove that current climate change is different from the natural changes that have always been happening and that it's being caused by human activity. That hasn't been done.
I regard people who deny man-made climate change the same way I regard intelligent design(ees?), young earthers, and anti-vaxxers, they're views don't matter to me.

This graph, based on the comparison of atmospheric samples contained in ice cores and more recent direct measurements, provides evidence that atmospheric CO2 has increased since the Industrial Revolution.

Only the science matters, and the science is telling us that the earth's atmosphere has heated faster during the industrial revolution than at any other time humans have been on this planet. THAT'S what matters.

Human civilization is less than 7,000 years old.
When we excavate the remains of past civilizations, we rarely find any evidence that they made any attempts to adapt in the face of a changing climate. I view this inflexibility as the real reason for collapse.
