“The Oceans will begin to boil…” – yes he actually said that, along with some other silly things. Watch this video:
One wonders, if Dr. Hansen realizes that no scientist has yet presented any credible evidence that the “oceans boiled” millions of years ago when atmospheric CO2 values far exceeded the 390 ppm we have now. Of course, given that this is a “Climate Progress World” production, such inconvenient facts don’t matter, as its all about the scare.
Hansen apparently has Venus on the brain. Even normally alarmist Wikipedia doesn’t embrace Hansen’s “runaway greenhouse effect” on Earth.
From http://en.wikipedia.org/wiki/Runaway_greenhouse_effect
The situation on Earth is very different from that which existed on Venus, as any terrestrial runaway effect is not irreversible on geological timescales. Potential runaway greenhouse effects on Earth may involve the carbon cycle, but unlike Venus will not involve boiling of the oceans. Earth’s climate has swung repeatedly between warm periods and ice ages during its history. In the current climate the gain of the positive feedback effect from evaporating water is well below that which is required to boil away the oceans. Climate scientist John Houghton has written that “[there] is no possibility of [Venus’s] runaway greenhouse conditions occurring on the Earth”.

Don’t you mean James Hansen of the Doomsday Clock and the Atomic Chickens?
He shouldn’t handle boiling acid so recklessly.
===============
Absolutely barking.
Hansen has completely lost it- bring on the men in white coats with a straightjacket.
Oh Puh-lease!
Something has gone unstable alright!
Is this what we get from NASA? Disband them!
I’m still waiting for NYC to go under water like he promised….
I’ll keep this in mind while I’m putting my plants in the garage tonight and covering up the outside faucets because of the freeze warning we have here.
Does ones brains go away with hair loss? If so,boy,am I in trouble.!!
That is the only thing I can think of to account for his nonsensical rubbish!
Maybe James ,and I will meet up in a sanitorium somewhere,someday,and opine on the loss of our senses[and hair],if not completely gone by then!
Awwwww, it would be nice to be able to just reach in and pull out a lobster, already cooked.
However, at least he’s honestly consistent. If you truly believe in a catastrophic tipping point, well, there is no well-understood upper bound on positive climate feedback, is there?
I wish he could read my remarks on nuclear bombs igniting the Earth and black holes created by the LHC swallowing the Earth. That might help him understand why his conclusions are truly laughable. He might look at the relative albedo for a completely cloud-enshrouded Earth and the Earth as it stands now, as well, and explain how the Earth is going to get all hot when 70% of the incident sunlight is reflected away by clouds. Or does he not believe in any sort of thermal instability that will carry all that extra water vapor up to where it hits e_s and clouds form?
Probably not. If he understood this, he’d understand why the feedback from water vapor isn’t, in fact, runaway solution positive, but is rather self-limiting.
On the good side, this sort of thing is precisely what we need to see from Hansen. The greater the level of hyperbole, the more the bullshit detectors of most living humans will start to sound the alarm. If he and Al Gore could only get together, perhaps with Michael Mann — well, one wouldn’t even need to satirize it, would one?

He reminds me of Michael Moore, Noam Chomsky, and Ralph Nader. They make a good living from getting the suckers to pay them lots of money to listen to garbage about what bad people they are. Personally, this guy should be just fired from NASA with prejudice.
Does he mean this about the Cayman vents are world’s hottest? You may have mentioned it, but I just saw it and decided to look through your blog.

And this is the guy that the History Channel, Discovery Channel, and the Weather Channel go to as an expert?
Hansen has definitely crossed the line from way out there to manically disturbed. To make the comments that he has show he has lost a grip on reality. The people in Congress need to see this video. It may act as a wakeup call on his credibility.
The Earth is now suffering from a run-away Jim Hansen effect.
That’s James Hanrahan to you-
http://en.wikipedia.org/wiki/Said_Hanrahan
Oceans boil at about 2:10 into his spiel. What a kook. It is hard to believe he is employed by the US Gubmint; but then so are Holdren and Chu.
The more I see and hear from this environmental wacko, the more he reminds me of Max Headroom.
He lost me at 01:35 when he started talking about it being unrealistic to transport life from our planet to another one. This guy may work at NASA/GSFC but he seems to have no concept of spaceflight and its future potential!
Captain Queeg comes to mind – strawberries anyone?
And AGW proponents people wonder why people find it hard to take Hansens’ views as being scientifically valid . The sad part is that thanks to his ‘management’ one of the worlds most important climate databases is now virtual worthless thanks to ‘adjustments ‘ so that it can support Hansens’ political goals .
He should stick to making muppets and quit trying to scare the children.
The oceans will boil over eventually. It will not be due to CO2 or human activity. It will be caused by the Sun in 4 or 5 billion years when it becomes a red giant and probably cooks the entire planet to a crisp. Or so they say!
After seeing the link, it’s too easy to mock Hansen, so I wont do it.
but I do have a message to NASA. ‘You guys should really pay attention here. Your reputation is at stake’
I watched the whole clip and tried hard not to laugh. This man is a complete idiot. He loves himself and his climate-pron so much, that he would sell his soul to swim in a boiling ocean.
I thought the thick sulfuric acid clouds were the main greenhouse driver on Venus. A real blanket that causes it to receive even less sunlight than Earth.
The Earth never experienced or will never experience a runaway greenhouse effect. For that the planet has to move closer to the sun.
The story about the melting of methane clathrates is still scientific speculation. There is no proof that this actually happened in order to explain the temperature rise.
Snowball Earth! Nobody really knows what caused the Earth to freeze over and it is still speculation if CO2 only melted it.
Hansen is becoming a believer of his own little fantasy world. Trapped inside his own beliefs. Some are right here: He should get fired from NASA. This is not a scientist speaking. He is a disgrace to himself.
this it truly sad…
….and even more sad that it’s contagious
