How To Talk To Your Relatives About Global Warming At Christmas Dinner

Just kidding. Over at Ben Shapiro's Daily Wire, a really persuasive case against global warming.

Here's point 7:

7. The CO2 cannot, from a scientific perspective, be the cause of significant global temperature changes:

The CO2 molecule is a linear molecule and thus only has limited natural vibrational frequencies, which in turn give this molecule only limited capability of absorbing radiation that is radiated from the Earth’s surface. The three main wavelengths that can be absorbed by CO2 are 4.26 micrometers, 7.2 micrometers, and 15.0 micrometers. Of those 3, only the 15-micrometer is significant because it falls right in range of the infrared frequencies emitted by Earth. However, the H2O molecule which is much more prevalent in the Earth’s atmosphere, and which is a bend molecule, thus having many more vibrational modes, absorbs many more frequencies emitted by the Earth, including to some extent the radiation absorbed by CO2. It turns out that between water vapor and CO2, nearly all of the radiation that can be absorbed by CO2 is already being absorbed. Thus increasing the CO2 levels should have very minimal impact on the atmosphere’s ability to retain heat radiated from the Earth. That explains why there appears to be a very weak correlation at best between CO2 levels and global temperatures and why after the CO2 levels have increased by 40% since the beginning of the industrial revolution the global average temperature has increased only 0.8 degrees centigrade, even if we want to contribute all of that increase to atmospheric CO2 increases and none of it to natural causes.
