@Ed Zachary
Thank you very much for your link. How did you find it? I had to pay $30 for my pdf file that I uploaded onto my Google docs. The link I gave works fine for Chrome and Firefox. What browser did you use?
Your welcome. I googled the title and the author with Internet Explorer, and it came up.

There is actually a second article, actually a note, by Emory Bunn re-doing the calculation of the first article. My guess is that you can't understand how two peer-reviewed papers about thermodynamics could be absurd.
I can understand how one paper criticizes the improper application of the 2nd LoT by creationists, and how another article properly applies the 2nd LoT to evolution, is not absurd.

One clue is that the author of the first article thanked the reviewers for helping him write the article. They may be fanatical atheists trying to make creationists and advocates of intelligent design look bad.
They also probably chew with their mouths open, beat their dogs, and recycle their bathwater. It doesn't make this particular argument unsound or invalid.

What part of my refutation of the article isn't clear? For example, does an airplane have a temperature? I have a YouTube video titled "Evolution and Religion" which may help you understand evolutionary biology and the second law of thermodynamics.

The other absurdity in the article is the idea that energy from the sun can decrease the entropy of a system. The entropy of a system increases when you add heat to it. For example, you make ice from water by extracting heat from the water. The entropy of the ice is less because there is more knowledge about the speed and location of the water molecules. There is more order or complexity in ice than in water. You are going from high entropy to low entropy.
This does not violate the second law because the water-ice system is not isolated.
Here is what the article actually said:
Quote:
The Sun heats the Earth through electromagnetic radiation
largely in the visible and near-infrared bands. The Earth
radiates electromagnetic radiation largely in the far-infrared
band into outer space, where it eventually joins the cosmic
microwave background.9 The Earth itself remains almost
constant in temperature, so the incoming radiant energy from
the Sun must balance almost exactly the outgoing radiant
energy into space. In short, the Sun heats the Earth and to a
nearly equal extent the Earth heats outer space.
Each of these “heatings” is accompanied by an entropy
change. The change of entropy for a system at constant absolute
temperature T, gaining heat Q quasistatically, is
S = Q/T
If the heat transfer is not quasistatic, then the associated
entropy change is greater than this quotient. The Sun emits
heat and hence decreases in entropy, while outer space absorbs
heat and hence increases in entropy. Meanwhile, the
Earth is nearly constant in entropy.
I didn't see where the article said the sun decreases entropy on earth. It said that by radiating energy, the suns entropy decreases.
