If global warming is left unchecked,How long before the earth in uninhabitable?

Answer 1

About 50 million years.

The earth just came out of a global cooling period that lasted from 1945 to 1975.

Before that, they was a global cooling period that lasted from 600 ad to 1880 ad.

And before 100 ad, there had been another period of global cooling.

Believe it or not, scientist cannot explain why the earth went thru any of those periods of global cooling, or the periods of global warming between them.

We do know the warming period from 100 AD to 600 AD was alot hotter than it is now.

In Britian, they could grow grapes for wine and exported wine during this period.

Britian is to cold to grow grapes now.

The above are reasons alot of people are doubtful about the current predictions.

If scientist cannot use ice core and tree core samples to explain why we had those periods of cooling and warming in the past.

Just how can they use the same data, to predict the future?

Answer 2

There is not a single person on this planet that can answer that question. Regardless of whether global warming is fact or fiction, it would be pure conjecture on anyones part to claim to know an end date. Remember that in the 1970's there were claims that we had less than a century before the next ice age. As with the news frenzy of today, it was sold to the public as fact and not theory. Global warming MAY indeed be real, but don't take it to the bank. Keep an open mind and think for yourself.

Answer 3

Entirely uninhabitable?  Probably never.  However, huge amounts of it would be intolerable for humans.  During the Paleocene-Eocene Thermal Maximum, high-arctic sea surface temperatures went above 70°F.  This is considerably warmer than anything off the west coast of the USA!  There would be narrow bands of relatively temperate land right around the poles, and everything else would be extremely hot by today's standards.

Answer 4

This is a difficult question to answer because, while it may take many years, centuries even, before even the most right wing global warming debunkers admit that it is real, once the runaway effect starts, it may not take long at all. If, say, in 100 years we realize that our planet is so polluted that not enough of the sun's energy is reflected back into space by the earth's albedo (reflective index) because our polar caps have shrunk beyond hope, things may develop very quickly, a matter of decades. I admit that I am only guessing, but that is the nature of exponential growth. Double a penny and get two cents, it is small change, but double a penny 64 times and you have an astronomical number.

Answer 5

Forever, barring other events.

Global warming will not kill us all, or even most of us.

But, unreduced global warming would still be an enormous disaster. Moving people away from the coasts, redoing farms and irrigation systems, and replacing things lost to coastal flooding, will cost huge sums of money. There are other effects. More details here:

It's not necessary to exaggerate the results of unreduced global warming. The reality is horrible enough.

We can reduce it enough to cope. Here's the plan:

Answer 6

Millions of years. Some parts of the planet will get hotter and drier, while other parts get colder and wetter. It has always been this way. Not long ago (geologically speaking) the Sahara was a tropical area and the middle of America was a shallow sea. The Mediterranean sea has been dry and closed off from the Atlantic ocean. Islands come and go along the mid-atlantic ridge. Florida has been underwater. Study the geological history of the planet before jumping into panic mode.

Answer 7

approximately one hundred years on the fee of human inhabitants explosion. we are already eating 50% of the completed annual biomass production of our in ordinary terms abode. that doesn't leave lots for something of life does it. All it relatively is going to take is a million greater % for people to be eating greater advantageous than 0.5. Mass extinctions have all started already with bee's and amphibians and there are various creatures on the endangered checklist. as quickly as we've destroyed the food chain our extensive kind is up. it is the upshot of our events and mindless 'circulate forth and multiply' attitude. And except humanity is composed of its senses right now or there's a important calamity to wipe us out, there isn't any wish in any respect. because of the fact people idiotically forget approximately approximately all warnings to their destruction. it relatively is going to bring about mass starvation, ailment and loss of life. practising Shaman... quantum physics rocks.

Answer 8

For me approximately 50-70 years and I won't give a damn. The earth will probably be enveloped by the sus atmpsphere sometime after that.

Answer 9

Don't know. It may stay inhabitable for a long time, although you wouldn't want to live in some parts of it.

Answer 10

the reality is that is not going to have the same consequences everywhere, there are parts of the earth that are going to be not altered as we think., if you want to know something more you can read dont know much about geography by kenneth davis
