Funny! It's a bit under 1 1/2 inches when I look at it sideways. I wonder why that is.

miles..... and since there is 14.7 pounds per square inch be exerted on the surface of the earth (allowing for the drop in pressure as altitude increases) so it would be wildly inaccurate however I wonder what the tonnage is for the entire atmosphere..... wait a minute, found it 5.5 quadrillion tons...

now the question is, as global warming progresses..... does that tonnage and the pressure on earth's surface decrease accordingly??

The total mass of Earth’s atmosphere is about 5.5 quadrillion tons, or roughly one millionth of Earth’s mass. Air is heavier at sea level, since the air molecules sit close together, compressed by the weight of air from above. As elevation increases, however, air molecules grow farther apart, and the air becomes lighter.

total weight goes down. I'm guessing that changes in the total mass and changes in the mix of gases in the composition of the atmosphere will dwarf that effect.

My guess.

Something is wrong.

I blew this up on my screen and measured with a ruler, but plugged in 5/8 for the earth diameter when it was really 5/16.

How can the Earth even still hold onto it being that far?

about 30 earth diameters.

Earth's Diameter at the Equator: 7,926.28 miles The average distance from Earth to the Moon is 384,400 km (238,900 mi)

So 30+ Earth diameters would fit between Earth and moon in that picture. I think that's about right.

And since you might want to know: Diameter of the Moon in miles: 2,159 miles
