I'm not saying anything is causing climate changes. There are many factors in this chaotic system, but CO2 is not significant.
You are wrong. the vast majority of climate scientists disagree with you, and decades of scientifically collected data shows otherwise. You fail to present data nor peer reviewed studies to support your idea.
Do scientists agree on climate change?
Yes, the vast majority of actively publishing climate scientists – 97 percent – agree that humans are causing global warming and climate change. Most of the leading science organizations around the world have issued public statements expressing this, including international and U.S. science academies, the United Nations Intergovernmental Panel on Climate Change, and a whole host of reputable scientific bodies around the world.

It is not just the US govt. that believes in climate change, and is willing to take action to combat it. China is taking action also, and they are not under any control of the US. They are not doing enough, because they don't have enough money, and in some cases they lack the correct natural resources, like natural gas to power enough electricity to get off coal.
After decades of fossil fuel-driven economic growth and industrialisation, China is now the world’s biggest carbon emitter, contributing almost a third of the world’s greenhouse gases in 2020.
It is also the most exposed to the impact of the climate crisis, in terms of its population size and number of environmental disasters, according to UN figures. Average temperatures and sea levels have risen faster than global averages, and in just one year since Cop26, China has experienced record-breaking floods and heatwaves, bringing with them severe energy crises.
China’s government has signed up to global climate pledges and is a big driver of renewable energy, but like with many countries, experts have raised concerns over the scale of the cuts.
“It is complicated,” said the Trivium analyst Cory Combs. “The general summary is: they are genuinely ambitious but also probably not enough.”
