When the surface of the earth reaches 212 % F. will any life exist?

Answer 1

There cannot be liquid water-based proroplasmic life at 212 degrees F. All other systems of life that have been conjectured are not proven to exist, even in the laboratories, so far.

I believe that there will be no functional life existing long before the earth reaches this point, if it does.. Same will be the case if the pollution pall shuts out the sun completely and the temperature plunges to say -300F, and a lot of the atmosphere becomes liquid and all water is long ago a solid.

Sci fi of course conjectures life forms that might exist under either circumstances, but cannot supply the factual biochemistry that permits such, aside from some suggestions on bioforming of humans over long period of time to use other biologies and structures.

But if modern ideas on stellar evolution are correct, we need not worry aout this for "billions asnd billions" of years. I think there are more immediate problems to solve, such as the supression of factual scientific data to promote political causes..and viewpoints.

Answer 2

Yes, there is a class of organisms that prefer hot hot temperatures called hyperthermophiles. Even above 121degrees F
However that scenario is not likely. I wonder how the hydrologic cycle would be effected.
In fact, I think it is not scientifically possible on Earth. Okay, so if you have more water vapor (which you will if the avg. global surface temp. is 212), there is a higher degree of cloud condensation. Clouds then increase the Earth's albedo cooling the atmosphere. Earth's surface heat will transfer to the atmosphere effectively cooling the Earth further. This cycle will continue.
I don't know how hot the earth can get, and still stay in a stable state for a period of time, but I do believe that it cannot reach 212degreesF.

Answer 3

There will absolutely still be life. Because that will just be the temperature at the SURFACE.

Life currently exists around volcanic vents in the deepest trenches of the ocean. These ecosystems are for the most part entirely closed - energy comes from chemicals instead of the sun, and no contact is necessary with the outside. It is hard to imagine a catastrophe so severe that it could destroy things under miles and miles of water. (Remember, high pressure increases boiling temperature and water absorbs huge amounts of energy)

Let us also not forget many of the ecosystems that exist and thrive in caves. Right now it only takes about a dozen feet of earth to completely shield you from the surface temperature variations... even in your extreme example I'm sure there will be any number of natural caverns that are quite capable of sustaining life. Even human life.

So no. Almost any amount of global warming is not likely to be the end of the story. The question is simply what kind of story we want it to be.

Peace.

Answer 4

Yes it would but there won't be much life.

At 212 Fahrenheit water boils and turns to steam but there's only so much water vapour that the atmosphere can hold so much of the water would just continue boiling. The world would become similar to a pressure cooker in that the temperature is at or above boiling point but much of the water remains as a liquid (in time it would dissipate into space).

There are some marine lifeforms that live in underwater thermal vents, not sure what they're called. The water here is under extreme pressure so is extremely hot, far in excess of the normal boiling point of water. These odd lifeforms would probably thrive - just about everything else would be well and truly cooked.

Answer 5

At that temperature all water would be in the gas form... so without liquid water not much of a chance of any life form we are familiar with surviving.

Answer 6

Yes. Life is amazingly adaptive. There are sea creatures now that live in the vents of undersea volcanoes. Something would survive and adapt.

Answer 7

Only if we all migrate to mars so we can start destroying that planet. Hopefully the Al Gore haters can put him aside and just look at the science and understand it before then so we can begin repairing Earth.

Answer 8

Roaches and Cher will be around no matter how bad the earth gets.

Answer 9

No, that would kill pretty much all life as we know it. Lucky for us it will not happen for several hundred million years.

Answer 10

It's not going to happen for a very, very long time, so don't worry.
