Climate change blather

Blah, blah, blah.

You don't do science by polls.  You do politics with polls, though.  That's what it is --- politics.

Once again, let me try to inject some scientific discussion into a political subject.

What the climate change folks want you to believe is that carbon dioxide will cause the Earth's climate to warm up unacceptably.  A bit of high school chemistry ( as I recall ), should cast some doubt upon that.  All gases, like carbon dioxide, follow a pattern of behavior with respect to temperature.  Temperature of a gas is proportional to the volume and pressure.

The equation PV= nRT is what I am referring to.  It is called Boyle's Law or the Ideal Gas Law.    Solving for T, where T is temperature gives:  T = PV/nR, where P is pressure, V is volume, n is number of molecules expressed as moles, and R is a constant.

If the Earth's atmosphere heats up, then it must expand in volume.  Pressure should increase as well. When you argue about global warming, you cannot just argue about temperatures.  You must also assert that these other numbers will move proportionally with temperature.

Let's run some numbers.

Let P = 1 atmosphere.  Let V= sea level barometric pressure.  Then you have (1 atmosphere) * (1 unit of sea level pressure, say 1000 millibars) = temperature expressed in units of temperature atmosphere and pressure.  Let's say 270 degree Kelvin atmosphere millibars.

Double the temperature to 2 * temperature.  Then Pressure times volume must equal 2 atmospheres-millibars degree Kelvin, right?  If pressure is the same, then volume is equal to 2.  And vice versa.  If both increase at the same rate , then you have the square root of 2 times itself, which is equal to 2. 

Thus when you talk about a warming atmosphere, you must also talk about barometric pressures and volume of the atmosphere.   The Karman line would go higher, don't you think?  This could be tested scientifically.  Pressures can be tested scientifically.

But the argument isn't about these things.  It is about polls.  Polls may make more interesting reading for most people.  Polls may be easier to understand.  Polls may be easier to lie about and misrepresent.  Polls can be misconstrued as science, when they are really about politics.

People don't want to read about the science.  They want to read about polls.  Then they claim that it is about science, but it isn't.  If it were, they would be talking about these other numbers.
