If bacteria with no technology can change the Earth from a Co2 heavy atmosphere to an Oxygen heavy atmosphere, triggering the first great extinction event, I don't see why a different organism with much higher technological advancement could not also trigger changes. Living organisms have impacts on the biospheres they exist inside, this shouldn't be mystical or surprising to anyone.
What do people think they are gaining by denying climate change.
Ignorance maybe, not much else.
People aren't denying that the climate changes. In fact, people on the right said that the climate naturally changes long before global warming was changed to climate change, when the warming modals were proven to be completely wrong.
There is science that says the sun that causes the natural fluctuation of earth's temperatures.
Here is a good write up on the Global Warming Hiatus without political overtones. It does a good job of explaining it in the context of how climate data are analyzed. There is nothing sinister going on.
There is science that says the sun that causes the natural fluctuation of earth's temperatures.
The science says that there are a multitude of factors that combine to effect changes on the climate, Milankovitch cycles being one of those factors. There is no science anywhere that says that the sun is the only factor that drives climate change.

Yes, climate does change naturally. And if humans didn't exist, then the earth would be cooling, based on historic trends; instead it's doing the opposite. This is why Tangier island in Virginia will be uninhabitable in a few years and nearly a third of Tuvalu residents are now climate refugees.

There is science that disagrees with you.
There is science that says the sun has the greatest effect on climate.

I never said the sun was the only factor in climate change.
However, the earth's movement affecting the amount of radiation reaching the earth's surface is a similar to the idea that it is the amount of energy that reaches the earth from the sun that causes the the climate to change, not the amount of CO2 in the atmosphere.
I'm not completely convinced that CO2 in the atmosphere affects global temps as much as claimed. It's a theory.
So yes, mankind adds CO2 to the air. There is no debate on that.
I don't think you know what a scientific theory is.
A scientific theory is a well-substantiated explanation of some aspect of the natural world, based on a body of facts that have been repeatedly confirmed through observation and experiment. Such fact-supported theories are not "guesses" but reliable accounts of the real world. https://en.wikipedia.org/wiki/Scientific_theory

The amount of solar radiation reaching earth varying over time relative to the position of the sun and that radiation being trapped by the greenhouse effect once it reaches the earth are not mutually exclusive concepts.
