will the sun grow past the size of the earth's orbit? and is that another reason it is getting warmer?

Question

the sun is expanding .ok

Answer 1

yes it will happen. but not for a very very long time. The sun does have a weather system that effects the earth but its shorterm not long term at this stage.

The earth will be engulfed eventually, in a few billion years. We will be either dead or elsewhere by then.

Answer 2

Great question, No, Based on spectroscopy of the Sun, it has enough hydrogen to more or less not to expand much past it's present size or general radiation output for about another billion years.

While it will expand past the present orbit of the Earth in size an interesting effect happens - since the overall giant size of the sun will mean that gravity will be less strong directly towards / from the center of mass of the sun and as a result the Earth and other planet's orbits will shift outward - so it may be that while the sun is expanding so is the orbit of the Earth at that time.


However, that's not the best explaination for why the Earth is getting warmer, to be fair, a few scientists (notably those funded by the oil/gas and coal industries), have posed an interesting and possibly plausible theory that there is natural variability in the Sun's radiation / heat output and (predictably) reached a slightly less plausable conclusion that this solar variation conveniently accounts for all global warming and therefore we can't and therefore shouldn't try to do anything about it.

However, The overall theory of global warming predicted as possible in the 1910's has more or less panned out as accurate since about the 1960's or so forward we've been able to collect excellent data environmental data on earth to support the theory as factual.

Disturbingly enough - while there were one or two political jabs the movie Inconvenient Truth actually does an excellent job of explaining most of the science behind the theory.

Answer 3

The Sun if it follows the example of other suns of its kind in the galaxies probably expand past the orbit of the earth. But if this is a factor at all it is totally insignificant to the problem of global warming. Probably comparable to the CO2 output of one moped.

On a more serious note thawing of the tundra will produce run away warming from CO2 production. The rotting of the biomass being the cause. When that starts anything man can do or has done to change the balance of CO2 Methane etc in the atmosphere will be insignificant.

Answer 4

O.ok., for starters-if the Earth stopped rotating on its axis, there could be little circulation interior the ambience as nicely because of the fact the oceans. this might impact the two our climate and the temperature of the ambience-plus its ability to eliminate impurities (smog, volcanic ash, etc.). If the Earth have been to quit in its orbit around the sunlight, it does no longer have sufficient forward speed=centrifugal tension, to maintain an outstanding course. at last gravity (the two from the sunlight or outer area), might take over, at which element it relatively is a one-way fee tag to the two of those. so a techniques, i did no longer see any point out of the Moon in those solutions. because of the fact it relatively is held in tension wager. the Earth and the sunlight, it would maximum probable hit Earth in the two situations. it is a foul hair day. Afterthought-it would even impact plate circulation under the Earth's crust, too. no longer that it would count-considering the fact that each and every person could be long gone. This (plate tectonic component), is yet another question...

Answer 5

Yes, the Sun is getting warmer and yes it will expand to a very large size in the future. But it will take billions of years. It is warming way too slowly to make any difference at all in less than a million years.

Answer 6

Hi. No. The Sun may eventually turn into a red giant and engulf space out to about the Earth's orbit, but that is billions of years away.

Answer 7

It will in about 4 billion years, but it doesn't explain global warming.

Answer 8

Perhaps
