Will global warming make Earth look like Venus in a million years?

Question

...and if so, is it possible that Venus looked like Earth a million years ago?

Answer 1

i highly doubt it.

honestly there is no way to really prove that there will be global warming,

if you notice that they base it on Temperatures and there has always been a pattern in the Temperatures each year..

1913-134

1922-136 which was the hottest ever recorded on earth.

1990-around 122.

(it starts going down again.)

1999-about 114.

Do you see what i mean?

its like a roller coaster...

but i'm not brilliant i'm only 14.

and i think that we may need to take per-caution with pollution in the air.

because all of those chemicals and carbon create a lot of heat.

i hope i could help out some:)

Answer 2

No.

1.  Earth is farther from the sun that Venus so it doesn't get as much solar energy.

2.  Earth has a lot more water, which will moderate higher temperatures.

3.  Earth has plants, which hopefully will keep the carbon dioxide levels from getting too high.

Answer 3

>Will global warming make Earth look like Venus in a million years?

Probably not. Even assuming that humans cause enough global warming to make themselves extinct, the warming process should stop and reverse itself soon after that point anyway, and by the time a few thousand years were up things would be pretty much back to normal (minus a number of species of plants and animals, but not enough to make a drastic change in the Earth's environment). And given that we will probably have reached a posthuman technological stage by the time our planet's atmosphere warms up by more than one or two degrees celsius, and that in any case our supplies of fossil fuels are rather limited, it appears unlikely that global warming is a threat to our civilization as a whole.

>...and if so, is it possible that Venus looked like Earth a million years ago?

No. Scientists are more or less certain that Venus's current environmental conditions have been around for most of the planet's natural history, which is to say several billion years. There is no reason why it should have been much cooler in the past few million years anyway.

Answer 4

No,

For the simple reason that humans won’t be around anymore to create the problem.  With the increase in temperatures the flooding of most or our cites (where most people live) and the destruction of our food supply humanity will render itself extinct in a couple of 1,000 years.  With humanity out of the picture the planet will have time to repair and restore itself.  Life will survive in the oceans and if the past is any indication some life forms will have either survived on land or will try to re-colonize the surface world.

People think that humanity is capable of destroying the planet, but we are not.  Even a full scale thermonuclear war won’t do that.  It will eradicate all life on the surface and most of it in the ocean.  The following global winter will kill even more life forms off, but the planet itself will survive and heal itself.  Already Chernobyl has the largest population of deer in Russia and insects survive inside of the reactor complex itself.  To destroy the planet would take more nuclear weapons then are in the total world supply.  Even then the planet would cool off and eventually restore itself before the sun dies.  Mother nature is tougher than we give her credit for, humanity is not so tough though.

One of the big problems with global warming is that is has a feedback nature where the problem gets worse quite quickly.  When the ice caps melt less sunlight is reflected and the temperatures start to shoot way up.  The problem with this is that few plants and animals will have time to evolve to the quickly changing conditions.  Humanity will stick around longer than some because of our technology, but in the end even that won’t be enough to save us.

Venus is a case of global warming run amok, but on a much larger scale than what we are seeing or will ever see.  Long before it gets that bad the conditions will get so bad that humanity will be extinct.

Venus has a lot of fuel in the form of volcanoes to keep the global warming going.  The constantly erupting volcanoes are spewing ash and smoke into the air to keep it so thick.  Air pressures can reach a surface pressure of 9,300,000 pascales, while the air pressure on Earth is only 101,300 kilo pascales.  This huge air pressure is what helps to drive global warming there.  Earth’s air pressure won’t ever reach that scale.

Eventually, no matter what we do the temperatures on the earth will rise; in the 4-5 billion years that the sun has left before it expands into a red giant.  At that point it will absorb the planets Mercury and Venus and it should push Earth into an orbit farther out.  In the process though it will melt the surface of the planet; then we should see temperature conditions like what we see on Venus now.

Not too many species have survived over 4 billions years, mankind may make a good effort, but the way we fight among ourselves I kind of doubt it; so we won’t be around to see the planet melt and turn into something like Venus.

Oh, by the way the impending collision with the Andromeda galaxy shouldn’t affect this problem one way other.  The stars near the center of the galaxies may be destroyed, and some stars may even be flung off into deep space, but that actual chance of any intergalactic matter colliding is pretty slim.  Out here in the Orion Arm the Earth and our Sun are pretty safe.

Answer 5

The answer is no. Venus is a planet of lava, rivers and rivers of lava. All global warming is going to do is melt glaciers in both poles and make the water levels rise to dangerous heights until they cover the whole or at least part of the Earth's surface. No, Venus has always been that way as far as anybody knows and there are no signs that there was ever any life there, which there would have been if it had ever resembled Earth. However, Earth did sort of resembled Venus when it was first forming and a long time before the dinasours first appeared.

PS: There is no way to prove that after world flooding there will come the next Ice Age. In fact, the only way for that to happen is for all of the continents to relocate near the Ecuador where they used to be about a million years ago.

Answer 6

ha ha ha  its a lot sooner than your million years  might be 10 /  yes 10 years...   but its NOT venus more the ICE AGE   look into it its really interesting it is going to be soon though  or watch the day after tomorrow that also gives you a good impression whats going to happen  but not millions of years  better 10  or if we lucky  20 years from now,. its just how things are  we do not have a grip on it   dont get me wrong its good to recycle and down oure carbon foorprint  but it wont make any changes , because simply we dont work together  the world doesnt work together if any one in the world would do that we had a chance  but we can hardly life / work together in our own country  so that wont happen  or the aliens would have a plan? mm who knows? who knows...

Answer 7

no, Global warming will probably kill most animals but the plants will thrive and take over therefore equaling out the co levels

Answer 8

No. Global warming and cooling cycle. Earth warms, then cools at fairly regular intervals. We are near the end of a warming cycle, and will start to cool in the next ten or twenty years.

The biggest problem is Goreism- AlGore's tactic to scare people into socialism by taxation, for no real purpose.

Besides, man's machines did NOT cause any noticeable shift in warming, and we can NOT cause any noticeable shift in cooling. But, we can pass laws that allow industry to add expensive, but ineffective mechanisms, such as catalytic converters, so auto manufacturers can jack up their profits.

If they want to reduce pollution, they should go back to engines like they had in the 50's and 60's which would power a mid-sized auto and get 28 miles to a gallon. Less gas used, less exhaust gases.

Answer 9

no.

Answer 10

NO. I just seen this on discovery channel. What will happen is earth would become a giant ball of nothing, but water...then another ice age type effect would set in and basically the earth would be a giant mass of ice similar to what it's like in Antarctica. :)

Answer 11

no

Answer 12

I don't know what the prospects are for a million years from now, but Venus is a prime example of the runaway greenhouse effect, that may be possible.  Since we are starting to do something about it, we may be able to stop global warming before it becomes irreversible.

Venus has the densest atmosphere of all the terrestrial planets, consisting mostly of carbon dioxide, as it has no carbon cycle to lock carbon back into rocks and surface features, nor organic life to absorb it in biomass. It has become so hot that the earth-like oceans that the young Venus is believed to have possessed have totally evaporated, leaving a dusty dry desertscape with many slab-like rocks. The best hypothesis is that the evaporated water vapor has dissociated, and with the lack of a planetary magnetic field, the hydrogen has been swept into interplanetary space by the solar wind.  The atmospheric pressure at the planet's surface is 92 times that of the Earth.

Venus's surface has been mapped in detail only in the last 22 years, by Project Magellan. It shows evidence of extensive volcanism, and the sulfur in the atmosphere is taken by some experts to show that there has been some recent volcanism

Venus is a planet with no intrinsic magnetic field, so it has no shield to protect it from the continuous attack of the capricious and violent solar wind. The planet is embedded only in a local magnetic field induced by the solar wind itself and perhaps by local magnetism derived from the surface.

Venus is one of the four solar terrestrial planets, meaning that, like the Earth, it is a rocky body. In size and mass, it is very similar to the Earth, and is often described as its 'sister'. The diameter of Venus is only 650 km less than the Earth's, and its mass is 81.5% of the Earth's. However, conditions on the Venusian surface differ radically from those on Earth, due to its dense carbon dioxide atmosphere. The mass of the atmosphere of Venus is 96.5% carbon dioxide, with most of the remaining 3.5% composed of nitrogen.

Answer 13

If it continues unchecked, yes.  But that's IF it continues unchecked.

And it is likely that Venus once resembled earth in physical surface conditions like temperature and atmospheric pressure.  No evidence that there was ever life there though, and if there was it would have been microorganisms.

Answer 14

No. Venus has no atmosphere. The Earth does.

Global Warming is a natural cycle. The Earth has proven to go through many warming and cooling cycles.

For example, the Ice Age and its period of warming.  

Answer 15

No and no.  Earth has had more C02 than it has today but that was millions of years ago.  There was more when the dinosaurs were around about 64 million years ago.  Fossil fuels and called fossil fuels for a reason.  They once were living things, usually algae algae and plankton, mostly small organisms, that have been turned into fossil fuels by heat and pressure.

Answer 16

No, even when the dinosaurs were around and CO2 levels were a lot higher than today, it was never as hot as Venus on Earth.
