Your car = the atmosphere of planet earth
The sun = the sun


The sun beats down on your car on a sunny summer day. Over the course of a few hours, the inside of your car gets even hotter than it is outside. This is because the radiant heat from the sun is being trapped inside the car. Even after the sun goes down, the inside of your car is still much hotter than the outside air because of trapped radiant heat.

Now, if you let your windows down the air inside of the car eventually balances with that outside. This is because the radiant heat is not being trapped!

Car windows are sort of like greenhouse gasses - they are see-through but they trap radiant heat. Pollution in the form of carbon, methane, etc. = rolling up the windows of your car on a sunny day.




Now, about the whole "global cooling myth" in the 1970s.

Again. let's use your car as an example.


You are in your hot car on a summer day. So, you turn your air conditioner on full blast to cool the inside of the car. Why is the car cooling down? CFCs! That's right, there is a chemical cooling down the temperature inside of your car.

CFCs being released into the atmosphere during this period before CFC aerosols were made largely illegal caused a slight cooling to occur during this time. As a consequence, we dissolved a hole in the ozone layer.


Any questions?

Where is my sammich?

And cool story bro.

Global cooling is apparently somewhat of a possibility due to changes in ocean currents in places like the bering strait and the gulf of mexico i think. Global warming is more likely though.

i don't get it. THEN WHAT IS YOUR HOOD?

Entropy always increases. The cooling would be merely cool air from the poles shifting towards the equator as the mean average temperature of the whole globe trends upwards.

I wash your dishes, your laundry, and iron your clothes and all I get is a "where's my sammich" ? It's in the kitchen! make it yourself!
