No. Claiming their argument is something other than it actually is is a flawed argument.
No, but arguing against the Earth riding on 4 elephants on the back of a turtle would be a flawed argument against biblical creationism.
In the case of this paper, one doesn't need much beyond the penultilate sentence of their conclusion:
Because the anthropogenic portion in the increased CO2 is less than 10 %, we have practically no anthropogenic climate change . The low clouds control mainly the global temperature.
If you know that the anthropogenic portion of the increased CO
2 is pretty close to 100% at the moment - from isotope analysis, and consistent with known emissions, then you can discard their conclusion as it seems to be based on that one factor.
Why spend any more time thinking about it?

Actually the paper looks pretty shabby, I'd have hoped to have done a more professional job as an undergraduate, at least stating my source for the cloud cover data.
One big red flag to me as an engineer with a physics background is the fact that they seem to be presenting
simple linear equationsa single equation for temperature effects, not even differential equations.
Still, if they managed to find a single equation with four variables to explain global warming, then maybe they need to publish this in Science and Nature, as this would be world-shaking if verified.
