Stephen Hawking - Earth could become like 'sister planet' Venus due to global warming

Stephen Hawking explains why life survives on earth and a 'worst case scenario' greenhouse effect that could make life on earth unlivable.

@ascolti I find the logic behind Stephen Hawkings 'crap' far more acceptable than the scientists that like to try and make out that the problem isn't as bad as people say it is. Whether or not other scientists agree with him is in no way relevant in my opinion, history is filled with great minds being doubted only to be proven correct in the future. This is one occasion, where I hope it is proven wrong. Either way, whether people admit it or not, this planet is dying and NOT at a natural pace.

Some say "ignorance is bliss" -- and this is one of the topics. I think most of the Earth's population -- who farm and work with land everyday notice the changes. Who are the skeptics? Do they have organic farms or a farm in general? Do they work on that farm or do immigrants? Do they go on nature walks at all or plant in a garden?? There are only a small pocket of skeptics --- most of whom have money to have a computer and internet service. What does money have to do with being a skeptic? lol

Paint all the rooves on earth white. Problem solved.

Many of us have our heads in the sand but it is time to wake up and smell the coffee. This is becoming more and more obvious every day, Christmas tornados, there are bugs out here in December LOL, this wouldn't have been possible in past decades. If we wait until it is more obvious I guarentee there won't be time. We need to act now for the sake of our children and children's children's sake.

@mohamedbaniissa where do you get this, not in a science book, check your facts, this is total bs. Earth cant get out of this if it starts it will kill all life on the planet and no way we could survive. we are releasing millions of years of carbon into the atmosphere in just a short march of decades, common sense should tell us we can't keep putting more into the atmosphere than it can process every year without consequences. Don't want to make you mad God Bless ;)

@Joeykm1972 Sorry Joey this is wrong, scientist are paid big bucks to say things like that but the consensus is against it and most of us don't take this kind of "science" seriously, the tobbacco companies used to do the same thing keeping thier products unregulated for years more. There isn't time to listen to 'bad' science we need to do something really soon or there won't be time. If the sun was getting brighter our science is very wrong, Earth has 500 million more years 250 million good1s

@RoTMGFleek It will happen long before then. When the polar ice caps melt the now thawed permafrost will release millions of years of stored up carbon, even if we stop (producing carbon) totally we can't stop the permafrost release. Scientist used to say 150 to 200 years until the ice cap melts, but it has been going much faster than expected. We might last another couple hundred years or less. I hope you can see the light and help us find a solution before it is too late.

@Dianaranda123 Look who's been our leaders, do a search with Bushes name and see what kind of criminal activity shows up, and past generations too. It would be funny if it weren't so sad and future generations will bear the burden, god help us each and every one. Oh we won't survive without earth, there will be no oxygen, cant go underground because no air, cant go to space because of the radiaton and if we could and survive because of the low g we could never live on earth again. Pure Greed

@Joeykm1972 You can hold on to your unfounded beliefs, not backed by science (maybe scientists that work for the oil companies LOL) But I am hoping we will wake up and see the light, if not our children or childrens children will and what will they think, we can do something if we start now. Hope you can reevaluate your opinion because consevatives are best to convince conservatives, they don't listen to Stepen Hawking that's for sure. Its common sense that this cant continue w/o consequences

[GreenGreenLimaBean]

@garith21 Christmas Tornadoes and nobody believes in global warming, when I was a kid that was unheard of today it is news but nobody really cares. LOL Your post show's you have some knowlege of the issue. I hope we can find many more people to help raise awareness before it is too late.

[GreenGreenLimaBean]

@RoTMGFleek I think more like 100 to 150, Scientist say the Polar Ice caps will melt in about that time but everything is moving faster than they predicted. With the ice gone,not reflecting back the light combined with the melting of the permafrost (which will release millions of years of built up carbon) these factors will push us over. You see if the permafrost melts we cant control that, even if we stop totally. Our planet is in big trouble, hope you can see it, we need people to raise aware

[GreenGreenLimaBean]

I was just thinking about that today. Ignorance represents a lack of knowlege for whatever reason, stupidity refers to intellegence. Most Consevatives don't seek out the facts therefor they are ignorant of them, only believing those with like views. This is why they won't accept the facts on global warming. Hope we can get everyone aware of this, I am try to do something every day to help. We must for the sake of God and his creation. Sorry your post is still at the top after a year. Peace! ;o)
