To deny the eclipse is to deny orbital mechanics.

To deny global warming is to deny thermodynamics.

The Earth receives energy in the form of radiation from the sun, primarily at the higher end of the infra-red to near ultraviolet range
It then re-emits that energy as radiation back out into space, primarily in the infra red range
The atmosphere is more absorbent at some wavelengths and less absorbent at others

Carbon dioxide is mostly transparent at higher frequencies, but mostly opaque in the infra-red range
The primary fuel source of humans since the industrial revolution has been fossil hydrocarbons, which are molecules composed of hydrogen and carbon which have been trapped beneath the surface of the Earth for millions of years
Burning hydrocarbons produces water and carbon dioxide (and soot, if there is not enough oxygen)
By burning a large quantity of hydrocarbons, humans have increased the proportion of CO2 in the atmosphere

Because CO2 is transparent at the wavelengths of light received from the sun, but more opaque at the wavelengths of light emitted by the Earth, there is a net gain of energy into the atmosphere which leads to an overall increase in temperature
Hotter bodies emit more radiation, so eventually the Earth will heat up to the point it is emitting as much energy as it is receiving again and thermal equilibrium is reached
However, the increased thermal energy in the atmosphere and oceans is predicted to have many undesirable consequences

Various other gases, such as methane, which are produced in large quantities by human activities have similar effects to CO2

His point is this, you scientifically illiterate fuck

The spectrum of light coming in is different to the spectrum going out. CO2 is transparent at more of the incoming spectrum than the outgoing spectrum, ergo it retains energy in the atmosphere rather than allowing it to escape to space. You can't argue with simple thermodynamics. Well, YOU can, but that's because you don't know any better.
