CO2 and Global Warming: I’m still not convinced.

Every time I get curious about how CO2 is impacting the Earth’s climate, it seems I always find articles that agree upon one thing: The amount of carbon dioxide in the air is 0.04%. Now, you have to understand just what that number means. If we were to add 0.96 percent to the 0.04 it would total just one percent of a hundred percent. The graph below represents the atmosphere. There are one-hundred squares, so each square represents 1% of the whole. That little black line in the bottom right square is the amount of CO2 in the air. And, that teeny-tiny amount of carbon dioxide is keeping the Earth’s excess heat from seeping out into space? Hey, I’m no climatologist, but this surely offends my common sense.

If we were to turn this graph into a grate that covers a heating duct, and then have experts claim that the little black line is causing your house to heat up more than usual (into dangerous levels), you’d call him crazy (wouldn’t you?).

This article states that “Scientists widely agree that Earth’s average surface temperature has already increased by about 2 F (1 C) since the 1880s,…” Two degrees? In 140 years of the most industrial time of smoke stacks and cars with zero emissions controls? Again, I’m no expert, but I find a 2 degree increase over that time period to be rather remarkable. It proves that our planet knows how to take care of itself quite well.

What I find most odd is the fact that it is well known that plant life NEEDS carbon dioxide in the air — it’s the stuff that forests grow on. So, the question that we and our scientists should be asking is, What would happen to all of Earth’s vegetation if we accidentally decreased the CO2 levels to zero, or close to zero? Would plant life diminish? Completely die off? Now, THAT’S a scary thought.

What’s missing in this whole climate change debate is the answer to how massive amounts of ice has been melting for the last 2.6 million years without any human interference, and how that particular process is separate from what we’re seeing now? How does a few hundred years of human industrialization get blamed for a process that started even before homo erectus evolved into homo sapiens?

What would it take to convince me?

Build two rooms of the same size right next to each other. Clean the air of one room, and make sure the other room has 0.04% CO2. Place highly sensitive temperature monitors in both rooms. If the one with the CO2 heats up more than the clean room, I will be convinced that such a minuscule amount of CO2 can make a difference.

I know I’m wrong, but after hearing the numbers involved, what I would expect the scientific community to be shouting is:

One thought on “CO2 and Global Warming: I’m still not convinced.

  1. Sadly, it is more complicated than you realize, and the “dangerous” warming of 3-5° is only about 10% of the 33° that CO2 and H20 vapor together already gave us. Nice imagery BTW, but the heat duct analogy isn’t adequate to the reality.
    (Not to mention that covering the heat duct cools the house).

    In terms of the analogy you’d need to call the duct initial size as 0.028 % of the floor area of the house, and they increase it to 0.41% – which is a 46% increase. (see below)

    So how DOES it work?

    I wrote an explanation here. The Physicists haven’t complained so it is pretty close.

    Remember, that it is 410 parts per million, but the other 999590 parts don’t have any long term effect at all. (H20 vapor is more potent but as a condensing gas it precipitates out too quickly to have a long term effect on temperature. It has to be boosted into place by the long term gases).

    So we really changed from 280->410, about 130/280 or 46% not 0.04%
