Venus has an extremely thick atmosphere, which consists mainly of carbon dioxide and a small amount of nitrogen. The pressure at the planet's surface is about 90 times that at Earth's surface—a pressure equivalent to that at a depth of 1 kilometer under Earth's oceans. The enormously CO2-rich atmosphere generates a strong greenhouse effect that raises the surface temperature to over 400 °C. This makes Venus' surface hotter than Mercury's, even though Venus is nearly twice as distant from the Sun and receives only 25% of the solar irradiance.
Studies have suggested that several billion years ago Venus' atmosphere was much more like Earth's than it is now, and that there were probably substantial quantities of liquid water on the surface, but a runaway greenhouse effect was caused by the evaporation of that original water, which generated a critical level of greenhouse gases in its atmosphere.[9] Venus is thus an extreme example of climate change, making it a useful tool in climate change studies.
So your answer is YES

yeah it is! Granted though this could not happen on earth for a LONG LONG time. The level of CO2 on venus is 96% ! Earth's is just .03% This makes for an oven on Venus, trapping heat on the planet making it roast. Article cited, read the first line. They use the same verbage as the question asks :o) Venus' atmosphere represents a runaway greenhouse effect

>Will worldwide warming make Earth appear like Venus in a million years? probable no longer. Even assuming that human beings reason adequate worldwide warming to make themselves extinct, the warming technique could provide up and opposite itself quickly after that factor besides, and with the aid of the time some thousand years have been up issues could be rather lots returned to favourite (minus fairly some species of plant life and animals, yet no longer adequate to make a drastic replace interior the Earth's atmosphere). And provided that we are going to probable have reached a posthuman technological point with the aid of the time our planet's environment warms up with the aid of extra advantageous than one or 2 tiers celsius, and that once all our supplies of fossil fuels are somewhat limited, it sounds as though no longer likely that worldwide warming is a danger to our civilization as an entire. >...and if so, is it available that Venus gave the impact of Earth a million years in the past? No. Scientists are extra or much less particular that Venus's present day environmental situations have been around for a impressive style of the planet's organic historic previous, it rather is to assert countless billion years. there is not any explanation why it is going to have been lots cooler interior the previous few million years besides.

Its mostly because Venus is closer to the sun, but the earth and Venus have about the same amount of carbon; Venus' is in her air and ours is sequestered in and under the oceans and in the Earth's mantle.
If you could release all the carbon in and on the Earth and put it in the air, it'd would be almost as bad as Venus, i.e; a runaway greenhouse effect.
Venus started off with oceans like the Earth but lost them early just because she is slightly closer to the sun. What a shame!

no i thnik that would really be a stretch even under really extreme global warming .earth and venus are different sizes different makeups and different distances from the sun mars may offer a better comparison if you have to use one of our other planets.

No, Venus is not. Venus is very different from Earth. It has a thicker atmosphere and it is smaller. Its atmosphere's composition is much like Earth's was billions of years ago.

That is a good question, I wish I knew. I think Venus has a lot more complex gases then we do. Plus they are much closer to the sun, so it has added heat.

No, Venus' climate is the way it is because of its short distance from the sun.
