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

[thirtyminuteslater]

Paint all the rooves on earth white. Problem solved.

[GreenGreenLimaBean]

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.

[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)

[GreenGreenLimaBean]

More people need to see this video and one's like it. This is an existential problem to all life on the planet, prudence dictates something must be done, yet some still dont believe global warming is a fact. They believe thier leaders and never bother to seek out the facts. Hope we all, Liberal and Consevative can join to solve this problem, I fear it is the only way we will get anything done.

[RoTMGFleek]

For those of you who are scared, this wont happen till MILLIONS of years... or next year :3

[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]

@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.

[claton95]

@topwomble George Carlin is a fuckin idiot

[Jayywatt1973]

Should I listen to probably the smartest man on the planet, or a twelve year old? Hmmm...tough choice.

[Joeykm1972]

Stephen Hawking is also failing to mention that global warming is also caused by the sun increasing in luminousity. This is where most of our global warming is occurring. The greenhouse gases just add fuel to the fire. When the earth was young, its atmosphere required more greenhouse gases because the sun was lower in luminousity.

[garith21]

@Joeykm1972

The sun hasn't increased in luminosity over the last few decades and temperatures have continued to increase on average even when solar activity is at a minimum. Not to mention the mechanism of increased luminosity takes much longer than a few decades to occur, which is primarily what the current case of global climate change is about.

[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]

@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]

@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

[Dianaranda123]

Exactly what the big evil bankers want, they dont care about anyone, except there own selfs, They probably already have plenty of ways to get away from earth.

Go Go bilderberg and co.

[GreenGreenLimaBean]

@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

[mohamedbaniissa]

YOU ARE WRONG stephen hawking you see the co2 came from the earth which means back when earth was new it had extreme weather the co2 got traped uder the earth and it will get trap again think back to dinosaur times who know that during that era they could also have extrime temeprts wich killed the dinosaurs the co2 got traped eventuly and know it has surfaced. nature is all about life cycles the only way we would turn like venus would be that something has to brake the cycle. by the way i am 12

[Donkeez2007]

@mohamedbaniissa I could have done a lot better than that when I was twelve. I could also spell properly. Does the phrase "positive feedback loop" mean anything to you? Because that's what Hawking is trying to explain. You seem very ready to discard the opinion of one of the most eminent physicists of our times.

[GreenGreenLimaBean]

@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 ;)

[mohamedbaniissa]

you are wrong steaven hawking you see the co2 came from the earth which means back when earth was new it had extreme weather the co2 got traped uder the earth and it will get trap again think back to dinosaur times who know that during that era they could also have extrime temeprts wich killed the dinosaurs the co2 got traped eventuly and know it has surfaced. nature is all about life cycles the only way we would turn like venus would be that something has to brake the cycle. by the way i am 12

[jetflyfiftysix]

"We don't know where the global warming would stop, but the worst case scenario is that Earth would become like its sister planet, Venus, with a temperature of 250 Centigrade and raining sulfuric acid. The human race could not survive in those conditions."

you guys are nerds :P

[sakinehbs]

Human race is so stupid, it needs to be destroyed. One out of 1000,000,000 or more comes out genius, the rest are hanging to religions god for help them.

[TheMtnLife]

@sakinehbs You proved your point well lol. How can you love nature so much after what it did to you, and you forgot a comma on the billion. 

[WeaselWJ]

@sakinehbs There are many atheists in the world, far more than one in 1 billion.

[BudCharles999]

Evidence for climate change:

*Parts of Greenland are living up to the name!!

*There are many natural disasters we would expect with climate change, including:

Cyclone Yasi, Hurricane Katrina, the Queensland Floods, the Australian Drought, the European Heatwave

*"Whoa, whoa, whoa!!" you say. "What about the super-cold WINTERS of the Northern Hemisphere recently?" Well, we should expect not just HOTTER conditions, but even more so, erratic conditions.

And I do belive we have about 15 years left.

[BudCharles999]

I predict about 30 degrees warming in the next 1000 years but by that time humans would have been extinct since 2200 and the other climate change effects will have phased out gradually. This would, however, mean a return to dinosaur-era conditions. Unnatural considering the fact the we are naturally supposed to be heading for an ice age.

[TheAlanisme]

lol wow

[onthecuttingedge2005]

if you consume then you must fart, it is the fart you are worried about.

[Theblizzardking]

"Anyone from Harvard, Yale, Princeton, or any good college, and who has a high IQ is just some stupid liberal who obviously is wrong about this global warming lie."--standard conservative.

[harrycolvile]

you now i totaly admire stephen he always realites some thing to space and explains it so well and because of him hu. i know as much as he does i guess stephen is my roll model i want to take on his place if he dies ( i think they shouls frezze him because hed love to see the future) go stephen!

[cr4yv3n]

@harrycolvile sadly the SF concept of freezing is not perfect ( that is to say you don't get preserved as you see in fiction ).

[MrWiLDAPEMAN]

we will be fine

[MrWiLDAPEMAN]

Global warming is a pile of horse shit

[chrisstevensjunior]

@MrWiLDAPEMAN Why is it fake?

[coolarjan1]

without the greenhouse effect we had not even Lived he means is the enhanced greenhouse effect

[GrimJackalGrin]

*cry* i sure hope its not already to late

[StarRosePink]

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

[miiror13]

@StarRosePink i live in canada i totally agree im out of the way close to alaska i see the changes in our valley very derasticly there was once a ver powerfull river in our suberb farm area anyways the river were there used to be bear moose and fish is now barley a small creek the eddyes we used to swim in that were 12ft deep or litterally not there any more and the forest out side of our vally has turned to a grassland the thing is we live in a rainforest area not a grassland

[GreenGreenLimaBean]

@StarRosePink I was thinking the same thing today Star, you know ignorance is not stupidity, stupid people can't comprehend but ignorant people can be very intellegent but unaware of the facts for whatever reason. Most conservatives just believe what they are told and dont seek out new information and this issue proves that. Sorry your post is still up top after a year, we need more people to raise awareness and try to shock people into action. tyvm ;o)

[The82ndParatrooper]

Global Warming is a scam by the government to make money. I thought Hawking would be smart enough to know that

[Rafabilbao]

It's funny how a theoretical physicist like Hawking can believe without a doubt the hypothesis that the tiny increase in CO2 concentration caused by human activity is seriously affecting the global climate and that, beyond the supposed ' models', is something measurable and observable!

[BeardedBill86]

@Rafabilbao Perhaps you should ask him why he does? :)

[StarRosePink]

@Rafabilbao Who says it is a small amount?? lol How many cars are there in the world?? How much coal do we burn for energy? On top of that there is pollution in other ways --- you should eat sea fish everyday for a year and come back to us to tell us how high your toxicity levels are, lol. Why are there pharmaceuticals and pesticides in our water? What does that do to our insides.? Also --- we have killed off nearly a third of all species on this planet. We our selves are bombs.

[Rafabilbao]

Es curioso cómo un físico teórico de la categoría de Hawking puede tragarse sin género de duda la hipótesis de que el pequeñísimo aumento en la concentración de CO2 provocada por la actividad humana, está afectando seriamente el clima planetario, y que, fuera de los supuestos 'modelos', es algo medible y observable!

[bellyzbad]

i hope plaint earth dont become like that

[1madaboutguitar]

Stephen Hawkins, you are a complete fuckin twat! We all know this a scam, you have sold out...prick!

[johnocfc17]

everyone keeps arguing with each other about this face it by the vtime this happens we'll all be dead so who gives a shit

[juliaxskiba]

@johnocfc17 we're not arguing we're discussing :)

[lovinit19791]

@juliaxskiba expression of oppinion....thats not arguing :)

[juliaxskiba]

@lovinit19791 precisely. hm i've just noticed you're double my age. scientific discussions - for all ages!

[lovinit19791]

@juliaxskiba indeed :) the younger you start the more you will learn....wish i had internet when i was a kid lol :p

[juliaxskiba]

@lovinit19791 yeah, i appreciate the internet a lot :)

you can find out all sorts! ha

[lovinit19791]

what a load of bullshit....the global warming bollox is not true. They blame carbon dioxide...what do you breathe out? what do trees and plants breathe?? Its a big lie to bring in a carbon tax....a tax on air!

Global warming is due to the suns solar flares and our position in the galaxy, its nothing to do with carbon dioxide

[juliaxskiba]

@lovinit19791 prove it.

[lovinit19791]

@juliaxskiba lol can you not use google??

news.bbc.co.uk/1/hi/sci/tech/3­869753.stm

[lovinit19791]

@lovinit19791 if you do a bit of research you will find that what you believe is true is infact wrong and misguided:( thats just one link....there are MILLIONS debunking the global warming rubbish.

We exhale carbon dioxide, plants breathe it. Its amazing what some people believe now days just because someone on TV said it :p lol

[juliaxskiba]

@lovinit19791 er no - i didn't say prove the positioning of solar flares i'm not bloody stupid. i meant prove that co2 has nothing to do with global warming.

[lovinit19791]

@juliaxskiba how can it???? CO2 is a natural element in our eco system. Without it we we not be here. Look through history and you will see hot stages and cold stages....its happened for 1000s of years. How comes the industrial revolution never caused "global warming" this was this biggest push in industry in history. Millions of tons more co2 each year for decades

[juliaxskiba]

@lovinit19791 you just said 'hot stages' do you understand what 'global warming ' implies? that the planet is getting hotter? bloody hell. industrial revolution? how about cars, used by practically everyone these days? as well as the much larger scale factories that are being used to manufacture goods these days? not to mention deforestation so less oxygen can replace co2, as well as the fact that global warming is aided by HOLES IN THE O-ZONE LAYER,caused by greenhouse gases not solar flares!

[lovinit19791]

@juliaxskiba If thats what you believe thats cool :) You wont mind being taxed on air.

I on the other hand do not believe the "global warming" lie, i have looked into it, both sides of the story. Deforestation is nothing, that would not cause global warming. If you look into this deeper you will find that algea is the biggest user of co2....and theres trillions of algea all over the world consuming more co2 than every forest on the planet.

[juliaxskiba]

@lovinit19791 obviously the taxed on air thing is crap, and i'm not saying i believe anything to be true. it may be the changes of polarity and all that crap causing craziness but i just don't think we can come out and say something's not true because we never know, it may be.

in fact, many people believe (as i'm sure you know) global warming is due from cows.

just goes to show that anything's possible.

:)

[lovinit19791]

@juliaxskiba What else would you call it?? CO2 is a byproduct of us breathing, yes it comes from car exhausts too but ultimatly it is a tax on air.

I try not to believe a great deal im told by the news lol or by people in government. Look at the lies about this oil spill for example...will tell the public anything to hide the truth and save their arses.

haha the cow thing would make more sense ;0)

[juliaxskiba]

@lovinit19791 yes but not just breathing seee ;D

hmm perhaps. mass executions of cattle. that would be an interesting approach to the situation.

[hfdpayner]

Nice vid but one part is innacurate he said that the seas warming could release co2 but it actually will release methane which is a lot stronger greenhouse gas than co2, triggering the positive feedback effect that caused the permean mass extinction. He probably said co2 because people dont realise methane has a larger impact on global warming

[christianmichelbach]

CO2 isn't the ONLY greenhouse gass, water vapour is also a greenhouse gas (and is the most abundant)...but I guess many people don't want to get rid of water.

[SimplyPhenomenal7]

co2 is a minority of the problem, as its only a small amount of the air. i think the suns rays are getting more powerful, possibly due to the ozone layer but i thought it was repaired. if its got a hole, then yes, co2 is a big problem.

[okiedokies]

F Off Stephen Hawking. CO2 has a half life of something like 15 years in the atmosphere. There is only so much fossil fuel to dig up and burn.

Earths system will purge itself of humans before humans can destroy it. Water, food, Disease, all have parameter boundaries which can lead the collapse of human excesses.

[jazcash]

Microsoft Sam's so stupid.

[SimplyPhenomenal7]

@jazcash LMAO

[hamoostaffat]

@jazcash Its not microsoft sam, its an audio board from a telephone unit back in the 60's. (just so you know)

[pivotkid85]

@jazcash

they should call it microsoft stephen, cause it sounds like stephen hawking

[malcjow]

He`s always talked rubbish - proberbly likes watching flash gordon.

[Cozzi0]

If we destroy all the rainforests around the world for wood i can see the earth dying out very soon after indeed, and with other threats such as bee disapearance and super volcanoe eruption i believe earth could look like venus but most probably mars in the next few hundred years.

[ascolti]

Well, everything is possible. So long as you know what you're talking about.

Stephen Hawking is talking utter crap on this front.

Odd how Cox, Dyson and Deutsch all totally disagree with Hawking. Who just seems more interested in getting headlines than working these days. e.g. Space aliens could come and kill us etc.

[MadMonkeyVids]

@ascolti Well what Hawking said about the tipping point on climate change is true. However I'm also sceptical about whether CO2 is the badass mofo, but that's not the real issue about fossil fuels, more the addiction we have to it as an energy source.

[5505miller]

@ascolti W ell soon as everything he said was facts, and was not a theory, I don't see were the crap could come from.

[ascolti]

@5505miller Nice. Put your fingers in your ears.

The reasons behind the running "greenhouse gas" effect on Venus don't apply on Earth. Why? Simply of hundreds of variables why.

What about Venus's size, distance from sun, volcanic activity. What about the negative feedback from Earth's atmosphere. Hey, lets compare Earth to Mercury or Pluto why don't we.

[5505miller]

I wasn't mocking your stance on his use of Venus, I was mocking your stance on global warming which came across from your comment as its a load of crap, which is wrong, if you believe we are not going through a state of warming, and you don't believe humans have nothing to do with it from the facts which are there in front of us made from independent and government scientists, then I find it naive personally.

[ascolti]

@5505miller You don't know me. Here's my understanding;

a) The climate changes, we are currently looking at a warming trend

b) There have been warming and cooling trends several times in human history.

c) Humans DO affect the climate - The urban heat sink effect for example.

d) CO2 IS a greenhouse gas, and human activity DOES cause it.

HOWEVER, the lack of negative feedback modelling in IPCC AR4 skews the results towards alarmism. Included it drops the 100 yr future increase to 2-3c. Not +10c

[ascolti]

@5505miller Incidentally, I'm one of the "independent" scientists you're eluding too. But you're a kid and you've been drinking the kool-aid. You can't help yourself.

[DaveIsParamount]

@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.

[DaveIsParamount]

@DaveIsParamount Addititonally, Mr Hawking says himself towards the end of the clip 'we don't know when the global warming will stop, but the worst case scenario is that earth would become like its sister planet'. He just said himself, that is the worst case scenario, not that it would happen, not that it looks like its going to happen, just it's the worst case scenario. I can't think of a worse scenario besides our sun taking early retirement, so there's nothing wrong with his ideas at all.

[ascolti]

@DaveIsParamount Look, this must be a bit tricky to understand. But alarmism is polluting science to the extent that only headline grabbing statements make it to the news.

Recent studies have shown that reducing particles from coal and diesel (nominally soot) will have the same or greater effect on the atmosphere than CO2 reduction. Did you see that story in the news anywhere?

How about the news that the arctic cooled from 1950-1990 to pre-industrial levels; despite rising CO2? See that one?

[DaveIsParamount]

@ascolti ??I do not find any of this 'tricky' to understand at all, not sure why that was implied, anyway I have indeed seen many of the reports of trends in both warming and cooling, and honestly i'm not in any way disputing that there is a massive amount of scare-mongering that comes with this, and as we know the media loves to hype things up even further. I completely understand that there are natural cycles that our planet goes through and that we are probably seeing that right now.

[DaveIsParamount]

@DaveIsParamount additional...again... However I am not willing to accept that human activities do not have an accelerating and thus detrimental effect on this trend. Natural cycles are all well and good, elements being proven to not be as 'dangerous' as reported are routine in this day and age and I always take reports on such matters with a pinch of salt. But one thing that I am sure of is that our species is messing up this place, possibly to the point of no repair.

[ascolti]

@DaveIsParamount See my comment to 5505Miller 5 days ago.

Look, if things are really as some pundits would make out, what is the point of doing anything? We might as well build a space ark and get off the planet. Of course, I'm being sarcastic at this point. But you can see my point.

My problem is that to fulfil one requirement we create another problem. An area in Canada the size of Wales is rendered lifeless in order to create lithium batteries for electric cars. That doesn't sound logical.

[DaveIsParamount]

@ascolti I agree, it doesn't sound logical... At no point have I offered a solution, for electric cars or otherwise, so I'm not sure why you bought that one up. I haven't offered a solution because I don't have one, but if governments continue the trend of encouraging profit rather than researching sustainable and safer means of obtaining energy then the problem will indeed only get worse.

[ascolti]

@DaveIsParamount "At no point have I offered a solution, for electric cars or otherwise, so I'm not sure why you bought that one up" - Sorry, I thought it was a conversation. I didn't realise we were point scoring.

[DaveIsParamount]

@ascolti And now you're turning sarcastic, you clearly have no intention of having a grown up discussion, merely choosing to sarcastically insult instead, great shame that an adult would behave worse than the majority of school pupils.

[DaveIsParamount]

@ascolti Finally, you seem to imply things about what people have said, rather than taking it as it has been said to you. I enjoy discussing things with people normally, but I dont appreciate people that will only accept their view as the definitive one and disregard other views as being stupid, "i know this must be hard to understand" and the comment about lithium batteries, both of which you have said with absolutely know basis from my discussion. Thus I leave you to bask in your opinion.

[ascolti]

@DaveIsParamount Woah. I think you're reading far too much into what I said. I was merely making a small point about how jumping to conclusions and pushing an agenda can have dire consequences, for example the use of lithium and the impact it's mining has on the environment as a whole.

Now I'm not going to read the rest of your post because I'm pretty sure it's going to be rather over the top....... [pause for breath]

[ascolti]

@DaveIsParamount ... [continued]

But as a scientist (particle physics) I'm perhaps a little more attune to the nuances of a unproven theory rather than a known fact. Climate science is a relatively new science and seems to have something to prove to itself........

[ascolti]

@DaveIsParamount ... continued again

It's lack of balance is only present in media presentations. The number of actual climate scientists (using the general temp) who believe in catastrophe is actually quite low.

But why let the facts get in the way of a good story.

I don't believe I have all the answers or that my word is god. I'm a scientist. So when I hear statements like "the facts are unequivocal" or that "there can be no disputes" that just gets my science radar going. :-)

Take care. R

[ascolti]

@DaveIsParamount Lets take the recent news with regards an ice shelf coming off the Arctic. Biggest in 50 years, but not the biggest ever. By a long shot.

And lest we forget history, what sank the Titanic again?

I'd send you the link. But youtube hates urls. So look this up in google

university of colorado arctic antarctic and alpine research

[tom4705]

@DaveIsParamount Chances of this happening are 1 in a million.

[WeaselWJ]

@DaveIsParamount The planet is dying? Extreme statements such as this are utter rubbish and serve to further deter the general public from actually understanding the impacts of global warming. The PLANET is not dying, but global warming could have some negative impacts on the HUMAN RACE.

[ASwiftHippie]

@DaveIsParamount ...The earth is not dying you twit.

[GreenGreenLimaBean]

@DaveIsParamount I am trying to do something everyday to make people more aware, even at the risk of looking crazy to some. I hope you and others can help and get somebody to do something, I guarantee by the time most realize it will be too late. Then they will be really mad because their leaders lied to them. When you think of it it is obvious what will happen, common sense dicatates if more carbon is put into the atmosphere than it can absorb then there must be consequences. tyvm ;o)

[markl328]

What he said was true.

[robostairs]

@markl328 earth could never become as hostile as venus, the worst that would happen is what has happend before ; deserts/rainforests extending to the poles.

[123456lvr]

First!
