“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”.

Will he buy me a new bullshit detector?
Mine’s permanently knackered now, the needle bent around the endstop!

James Hansen: the Crazy Cat Lady of climate science
NASA, I’m disappointed in you.
Are only nutters left in the Alarmist camp?
Wentz et al in SCIENCE for July 7, 2007 in a Peer reviewed paper: “How much more Rain will Global Warming bring ?” OBSERVED that a one deg C rise in the global mean surface Temperature resulted in a 7% increase in each of the variables: Total global evaporation (of H2O), Total Atmospheric water content, and Total global precipitation (of H2O).. They also reported that the GCMs also predict the same 7% increase in Total global evaporation and total global precipitation. Everybody understands that total global precipitation and total global evaporation must balance, or the oceans would end up over our heads. The first (evaporation) is simply a consequence of the Clausius-Clapeyron equation.
But the GCMs only predicted; excuse me, that’s projected, a 1% to 3% increase in Total atmospheric water content. That 3:1 fudge factor ratio is obligatory in climate “science”, and of course the GCMs are somewhat more dependable than actual observed measured data.
Not reported by Wentz et all, but also self evident, is that precipitation is often accompanied by (precipitable) clouds, so a 7% increase in precipitation likely means a 7% increase in precipitable clouds, which could be, more cloud area, optically denser clouds, longer cloud peristence times, or cloud movement to higher moisture locations.
So it is reasonable to conjecture that this pattern would repeat for some increases in Temperature.
But, it is also self evident, that ANY increase in atmospheric water content, including clouds, MUST result in LESS solar energy reaching the earth surface, since H2O absorbs significant parts of the solar near and IR spectrum.
So how is the earth’s ocean going to boil in the face of ever diminishing surface solar energy ?
He should be fired for being either incompetent or a liar.
He says:
All the species will be gone from global warming.
The oceans will end up in the atmosphere.
The ice sheets will be gone in a century.
Just add the “warming” from methane, water vapor and carbon dioxide together to get an accurate picture. Their absorption bands don’t overlap or anything right?
I’m shocked that anyone with a basic education in climatology would make these statements.
Starburst at the top (end?) of skyrocket trajectory
I had a conversation with a retired left-wing professor the other night at the campus bar. He agreed that CO2 wasn’t a problem. But he figured that ocean acidification would get us instead. I don’t think he realized the implication of what he was saying. You can’t simply make a multi-trillion dollar mistake, say “so sorry”, and then expect the public to roll over for your next great idea.
The true believers will continue to believe in one form of apocalypse or another, but if their CO2 arguments collapse it will be fifty years before the general public will again listen to them.
Wow! Dr. Hansen is completely insane!
This video was produced by bt.com (Big Think), but after this drivel, they should certainly consider changing it to bs.com.
The Cause is certainly getting desperate following Climategate 2.0, the Durban Debacle and no warming since 1998, falling: AMO, PDO, ENSO sea temps and falling ocean levels and what looks to be a weak solar cycle 24.
If NASA had any integrity, they should fire Dr. Hansen immediately, but with BHO as president, this will never happen.
Well, Dr. Hansen is on record now, and this video will come back to haunt him….
Disgusting!
The reference to strengthening storms eventually causing something analogous to what happened in New Orleans, suggests that strong storm Katrina was the cause of all the flooding. My understanding is that the cause of all the flooding in N.O. was the ineptitude and failure of Big Gov’t; local, state, and last – federal, but mostly local and state. Primarily the mismanagement of levees and marshes.
“He maketh the deep to boil like a pot…He is king over all the sons of pride.”
Had no idea Hansen was just a straightforward Old-Testament catastrophist nutbag — he’ll be hanging around on streetcorners in sandwichboards any day now, predicting the end of the world, and still collecting his NASA paycheck.
Hansen 2003:
”We have taken over control of the mechanisms that determine the climate change.”
http://www.nytimes.com/2003/11/11/science/when-will-the-next-ice-age-begin.html
Yep. James Hansen has seen the naughty yellow pixies who pull the special, magic Climat-O-Levers which control the weather (and) have been paid by evil capitalists with fat cigars in their mouth and $ signs on their pinstripe suits to make the world’s climate all horrid.(h/t Delingpole)
Obviously the guy is a kook but don’t kid yourself that the pro-AGW crowd will watch this and realize that Hansen is unbalanced. Every believer I know will eat this up like it’s cookies and ice cream.
Wow! He gets paid to make these pronouncements?
FISH SOUP, ANYBODY?
He forgot to say: the moon will turn red, there will be earthquakes in divers places, there will be wars and rumours of wars, and they will see the (insert belief of the day) coming in the heavens….
this man hansen brain is in a real mucking fuddle.
Insane sociopath or just a pathological liar?
Hansen’s giving his employer (NASA) a new meaning for the acronym.
James Hansen: Not A Scientist Anymore
“Dr. James Hansen of NASA GISS, unhinged”
When was he ever hinged?
NASA surely employs some very, very strange people. Some of them are – allegedly – real scientists.
“…you could melt the ice sheets in less than a century”—is this perhaps the easiest to debunk? We have a pretty good idea of how much energy comes in from the sun over a century (and an idea of how much leaves), and the mass of the ice sheets; there are complicating factors (not all of the energy is available to melt the ice, there’s difficultly getting the energy to the ice (the elevation of Antarctica’s ice cap surface), and other things, but it should be pretty easy to set bounds on what is possible. At 30 million cubic km of ice for Antarctica alone, that’s a lot of ice per year to melt, and an upper practical limit on how much energy enters and stays in the system.
Let the rationalizations begin!
R.Gates? a physicist? Lazy Teenager? Anyone?
We would need 4.00 x E26J for the ‘oceans’ to boil. Hansen is a loon.

Pronouncements like this one from James Hansen don’t happen in an ideological vacuum.
In light of the near- total propagandization of the populace by the warmist collaborators, one could easily assume that it will be fifty years before people stop listening to them.
