David Keith on the BBC HARDtalk Show Geo-Engineering Stephen Sackur

Few branches of science divide opinion as sharply as that championed by Professor David Keith. He's one of the pre-eminent geo-engineers striving to find new ways to combat global warming, by altering the way the sea, the clouds and the atmosphere work. This isn't a replacement, he says, for the political drive to reduce emissions. But is geo-engineering a cost-effective, emergency stop-gap, before the effects of climate change become irreversible, or a dangerous leap into the unknown?

A more sophisticated approach, using multi-layered nanoparticles (consisting of aluminum and barium titanate), was published by David Keith in 2010. He suggests utilizing the effects of photophoresis to increase the amount of time the aerosols stay airborne".

Aerosols could be injected into the upper atmosphere to engineer the climate by scattering incident sunlight so as to produce a cooling tendency that may mitigate the risks posed by the accumulation of greenhouse gases. Analysis of climate engineering has focused on sulfate aerosols. Here I examine the possibility that engineered nanoparticles could exploit photophoretic forces, enabling more control over particle distribution and lifetime than is possible with sulfates, perhaps allowing climate engineering to be accomplished with fewer side effects. The use of electrostatic or magnetic materials enables a class of photophoretic forces not found in nature.

Photophoretic levitation could loft particles above the stratosphere, reducing their capacity to interfere with ozone chemistry; and, by increasing particle lifetimes, it would reduce the need for continual replenishment of the aerosol. Moreover, particles might be engineered to drift poleward enabling albedo modification to be tailored to counter polar warming while minimizing the impact on equatorial climates.

Thanks, Martin! --Spooner

@elMONGOreal No worries dude.

[tnman37040]

hes the biggest moron to ever set foot into the scientific community. and a dangerous moron at that. hes a terrible liar, and when confronted with the facts, shifts and gets nervous. him and his geek buddy bill gates need to be held responsible for wrecking this planet, and his other buddy the arrogant ass ken caldiera.

[durongloria]

you do not have permission to do this to my air you son of a bitch !!!

[lindasayshello1]

The reason why this planet is not protected any more is because of the Illuminati USA GOVERNMENT SYSTEM THAT DON'T WORK ANY MORE, IS THEM OVER USING THE HAARP MACHINE THEY HAVE BEEN USING ON MAN KIND FOR A WHILE NOW, AND BILLIONS OF WATTS IS WHAT RIPPED ARE PROTECTION FROM ONE SIDE TO THE OTHER. ITS ALL PART OF THERE PLAN TO KILL WHAT GOD MADE.!

[lindasayshello1]

He is an Illuminati to then because Bill Gates is an Illuminati to. If you Morph some one to find out if they are, and if they are please post for the rest of us to wake up to.

[lindasayshello1]

Some one should find out if he is one of them reptilians, possessed soul of Satan. You just take a close up of the person you want to find out about, and slow the video down 20+ times, and if they are possessed by Satan, then you will see for a few frames of them Morph. Snake like eyes and teeth, like in the Garden of Eden.

YOU CAN DO HARDLY ANYTHING, EXCEPT PROTECT YOURSELF...

Phoenix tears cannabis oil, one drop per month (at least), could help deflect the toxins from damaging your nervous-immune-organ systems. So, take hemp oil and outlast the sheep... That's all you can do.... for yourself and loved ones.

[MrCannatopia]

Fuck all this noise....

Prof. Keith killed it in his first opening statement (answer to question, "What is geo-engineering?")

How do we combat global warming (two ways)?

Grow plants to suck up CO2 or spray the sky with reflective metals to deflect sunlight.

Wow, same thing with cancer as global warming....

Radiation-Chemotherapy (Solar Radiation Management, Chemtrails)

Hemp Oil (Grow the cannabis plant everywhere, it sucks up carbon emissions!!)

[borrible]

@MrBillytree BBC is paid to obscure the truth and cough inpolitely throughtout the transission of REAL news... the tool of the Lower RHS of the City of L. Illuminati. Check clapham common on google earth, link it up to city of Lodon, and see if you can see th triple pyramids laid out over an 11km region. 11 x3 = 33 its messed up how they control us and we dont give a shit, the shit rly will hit the fan when ppl find out...

[HAPPYxGEORGE]

Better copy of it on my channel........ If you wish to copy it and use it on your channel, your most certainly welcome

Just this past week I did a search on chemtrails after experiencing a heavy assault on our own area once again i wanted to see who else got hit I found it was pretty much a Global effort this last time. Australia S.Korea Brazil Mexico Germany Sweden Holland Canada all 4 corners of the US & interior The UK people posted vidoes on Nov 14th heavy chemtrail spraying & we then experience severe weather again compared to last springs tornado outbreak. This is wrong & a crime as far as Im concerned
