How can anyone deny climate change?
Let's imagine for a moment that all the data was made up by climate scientists to push an agenda, and let's ignore all real-world observations of how things have changed over time.
That still leaves two undeniable things:
>humanity takes carbon out of the ground and turns it into CO2, and there is no process for that carbon to go back into the ground even in the long term let alone the short term
>CO2 creates a greenhouse effect, as can be seen with how Venus is far hotter than a planet that is far closer to the sun, and as can be understood with pure optics

I've never heard an argument against either of these things, because denying basic science is even dumber than denying data. But if you believe both of these things, you can't possibly deny that humanity must be increasing global temperature.
