This should put an interesting "spin" on things?

Question

Following up on Brancomicguy's question "what would happen if we started clumping asteroids and planets...?"

It is believed that the earth is slowly increasing in size. Possibly because of the space dust continuously raining down on our planet.

Taking into consideration what I have said in my answer to BRANCOMICGUY's question, would'nt this be another possible explanation to global warming?

People! Please take the time to read my answer to BRANCOMICGUY's question before answering my question.

Answer 1

Hi. I read your other answer. See below. The atmosphere is almost 93,000 000 miles away, so don't worry. Earth is more that just wonderful. It is exceedingly rare in my opinion. Together with the Moon, her oceans, her temperature, her atmospheric environment - all these make for an unusual combination of life supporting qualities. We should cherish this home we have.

"This is wonderfull idea! Just imagine if could expand the size of our tiny little planet.

On the downside though, it is believed that the dimensions of earth is perfect for the exixtence of life on it. if we made her any bigger, our atmosphere would be too close to the sun, and earth would fry like a tomato.

Just my opinion."

Answer 2

The earth is slowly increasing in mass from space dust. However this happens at an extremely insignificant rate. There is not enough dust left in the solar system to amount to anything.

Even if earth did get bigger in say 1 billion years. I dont see any way how that in itself would effect global warming. The earth would keep the same orbit. If the earth got twice as wide, then yes we would be a bit closer to the sun, but the difference would again be very small.

so its not an explanation to global warming whatsoever

Answer 3

The theory is that 2 tons of space dust is raining on us every day.
Even if this is true, I doubt that it would create global warming due to the very nature of the stuff. It is said that it has the consistancy finer than talcum powder.
Now how in the world they figured that out I don't know, but I would assume they used a collector grid on a satellite and measured it.
The continuing theory is that it is burning up in earth's atmosphere and so doesn't collect up there and so wouldn't affect the atmosphere.

Answer 4

No.

The key issue is that global warming refers to an increase in temperatures that has occured only over the past 100 years. Accretion of matter from space has been happening fo billions of years. There is no reason to believe it has changed in the last 100 years, so it cannot account for a change in climate.
