BPSDB After babbling on with a number of factoids about global population, the land surface area of Texas and so on, the ‘Tennessee Conservative Watch (TCW)” asks “Considering that the earth’s atmosphere extends 50 miles up from the surface, how can anyone with half a brain think that humans can do anything to change the atmosphere much less the earth’s climate?”
What the TCW has done is parrot one variation of the popular “common sense” arguments that climate change Deniers like to use. They all include some form of “common sense tells you” coupled with some completely irrelevant, misleading factoids. They are based on an appeal to ‘use your brain’, so let’s try that and see what happens.
“Mankind occupies less than 4 tenths of 1 percent of the surface of the earth.” TCW
Common sense tells you that:
Here, try this logic with any housemates you may have: ‘I occupy less than 4 tenths of 1 percent of the surface of this house/apartment, how can anyone with half a brain think that I can do anything to change the amount of dirt and mess?’ Think that might work? I doubt it, even if your housemates have only half a brain.
It isn’t just the physical space you physically occupy that matters, it’s how much of the space that you use. Our actual use of the Earths’ land surface is 83%, and we have brought the oceans to the point of collapse even without climate change.
Common sense tells you that:
There are many examples that we all know of where very small amounts of something can have a huge effect. A typical bullet weighs about 250 gms, less than 2 tenths of 1 percent of your body weight, but it can still kill you.
That is because of the kinetic energy the bullet picks up when fired and then transfers to your body in the form of damage. Sort of like the way CO2 picks up thermal (heat) energy and then reradiates (transfers) it, some back to the Earth.
Of course if you were to eat the lead bullet in powder form it would take 30 times less to kill you. Let’s not even start to talk about radioactive substances where amounts so tiny they can hardly be seen with the naked eye are deadly.
A non-lethal experiment would be to powder just 1 gm of a magnet and blow it into your computer (something no one with any common sense would ever actually do) and see if that makes any difference .
Or take 250 gms of water (about 1/4 qt), a perfectly natural substance that makes up 60% of your healthy body, and that is essential to life; just like CO2. If you poured the water into your lungs and kept it down you would choke to death; a good example of how an abundant, natural, necessary substance can be lethal when there is a little too much in the wrong place.
