The current climate change is not only mostly anthropogenic, the warming is occurring faster than anytime in the paleo-record.
Carbon dioxide has been observed and known as a greenhouse gas as early as 1861, John Tyndal.

The amount of warming due to increased CO2 was calculated closely to what we are currently experiencing in 1896, Svante Arrhenius.

In 1931, American physicist E.O Hulburt ran calculations to determine the effect of doubling carbon dioxide came up with a figure of around 4°C of warming. Current calculations as well as observations are 3.0-3.5°C.

And I can go on showing that global warming and climate change due to increased atmospheric carbon dioxide is real and well established well before politics and social media begin it misrepresentation of climate science.
But I'm sure your next question is how do we know the increased atmospheric CO2 is due to fossil fuels? Actually quite simple. The ratios of 12C & 13C are noticeably different from those contained in fossils and that of naturally occurring atmospheric CO2.
