Understanding the greenhouse effect
Sometimes I wonder if I learned the same thing that everyone else learned in school about how our planet operates.
Global warming is political
When we have cloud cover, the Earth below gets 10-15 degrees cooler. Physicists have told me that whether it be CO2 or H2O, the Earth gets cooler, not warmer, when these gases increase in the atmosphere. Why? Because the Earth isn't a greenhouse. A greenhouse has glass walls. It's the glass that traps the heat, not the CO2.
Global warming, if it occurs at all, is a political condition, not a meteorological condition.

Wow I am not even sure where to start with this. First off cloud cover is water droplets. The water droplets are absorbing the light and provide shade thus cooling down the area below. And actually if you have enough humidity (more H20) in the atmosphere it will get warmer - been to Florida recently?
But the basic premise of this letter just pisses me off more from how scientifically incorrect it is. I would be curious exactly which physicists this guy is talking to. The reason certain gases cause the greenhouse effect is due to how elements interact with different light frequencies. Since Mr. Jarvis and physicists friends seem to have all the answers then why don't they tell me why the sky is blue? HMMMM?
The earth atmosphere absolutely does act like a greenhouse, if there wasn't some type of greenhouse effect then nothing could live here and our planet would be cold like the moon. But even with the absence of glass walls the gases in our atmosphere does create a greenhouse effect by not allowing the thermal energy of the sun to escape back into space.
The concern now is that we are adding considerably more gases to the atmosphere thus increasing the greenhouse effect. From a political standpoint I think it is impossible to have this discussion with people that align themselves with a party that has had a long standing war against science. I find it way more effective to talk about the political ramifications of continuing to allow our country to be dependent on countries that hate us for our energy needs. That seems to get through the thickest of Republican heads, even Rep. Urquhart!
Did I mention these people scare me?
