Guest essay by Eric Worrall

The US Senate is considering funding for albedo modification geoengineering experiments – pumping particles or aerosols into the stratosphere, to reflect sunlight back into space, and counter the alleged impact of elevated CO2 levels on global climate.

According to ScienceMag;

To fight global warming, Senate calls for study of making Earth reflect more light

Budgetmakers in the U.S. Senate want the Department of Energy (DOE) to study the possibility of making Earth reflect more sunlight into space to fight global warming. Earth’s reflectivity is known as its albedo, and the request to study “albedo modification” comes in the details of a proposed spending bill passed by the Senate appropriations committee to fund DOE, the Army Corps of Engineers, and related agencies for fiscal year 2017, which begins 1 October. The bill does not specify how much money should be spent on the research.

Critics argue that albedo modification and other “geoengineering” schemes are risky and would discourage nations from trying to reduce their emissions of carbon dioxide, the heat-trapping gas that comes from the burning of fossil fuels and that is causing global warming by absorbing increasing amounts of energy from sunlight. Still, climate researchers say they should find out what its potential of albedo modification might be.

“The recommendation is great,” says Joyce Penner, an atmospheric scientist at the University of Michigan, Ann Arbor. Albedo modification “is not a solution to global warming, it is only a way to avoid, perhaps, a tipping point in the climate.” David Keith, an atmospheric physicist at Harvard University, says, “Ignorance is not a good basis for making decisions, so learning more about this is extremely valuable even if we find out that it will never work.” Keith adds, however, that the few existing studies suggest albedo modification could help ameliorate some effects of global warming.

The call for further research comes in a bill that would provide $5.4 billion for DOE’s Office of Science next year. It also builds on the recommendations of a February 2015 report from the National Academy of Sciences (NAS) entitled Climate Intervention: Reflecting Sunlight to Cool Earth. That report warned explicitly that albedo modification shouldn’t be deployed now because the risks and benefits were far too uncertain. Still, the committee urged further research to find out what those risks and benefits might be.

It is difficult to imagine a more ridiculous waste of taxpayer’s money.

The US spends taxpayer’s money regulating coal plants, forcing any coal plants which survive Obama’s war on energy, to fit expensive scrubbers, to remove particulates from their emissions.

If this measure is passed, the Department of Energy will get to spend even more taxpayer’s money, burning sulphur and other compounds, to generate and emit the same types of particulates which the US government previously forced domestic US coal plants to scrub.

All they need to do is create white plastic sheets with Styrofoam Floatie edges and float them in the Arctic/Antarctic Oceans during the summer. They will naturally conglomerate in the ocean, as images of floating plastic garbage islands would seem to indicate, and would also separate for the occasional passing ship of fools

It is now brighter sunshine (and warmer) due to less particles in the air.

They must want more acid rain in order to grow blueberries?

oeman50

All you have to do is turn off the SO2 scrubbers on existing power stations and voila! you have lots of sulfate particles in the atmosphere to reflect the sunlight.

Just put sulphur back in jet fuel. Use sulphur free from one tank fot take off, so smog controlled, then swap to high sulphur at altitude where you want it. Zero cost as removing t he sulphur adds cost…

Bryan A

You most not be from Californie … Way back when, MTBE was a required additive for fuel and fuel providers raised their prices to be able to retool their facilities so it could be added. Only later was it discovered that MTBE in boat motor fuel contaminated fresh water used for drinking. Fuel companies then charged us more to not put it in

Slacko

Tiburon, yes they are. Surprised you got that through the filter. We do our best to follow them from their location of origin, usually anywhere from Richmond to Moss Vale, as they drift out over the Sydney basin, gradually spreading out to form what we call “white sky.” How could H2O do that in a relative humidity of less than 15% on a bright sunny day with no other type of cloud? We decided to ask the BOM but our questions became too difficult …er.. inconvenient.
Only purely empirical evidence will be acceptable on this site, such as (hopefully) that from spectroscopic analysis of such trails as they are being laid down. Unfortunately we’re running a little short on funding until the Big Oil cheque comes in.

JohnKnight

They’ve been doing over me (Northern Central California), and/or to my West, for at least a decade. Blatantly obvious, massive at times, not the slightest doubt in my mind.

JohnKnight April 21, 2016 at 10:02 pm
Thanks John,
A couple of weeks ago there were trails appearing in widely separated parallel pairs, seemingly originating just west of Katoomba. They extended as far as I could see to the north and south without seeking a higher elevation. When a pair was directly over my house I estimated a separation of about 15 to 20 degrees. At that time the next pair would be visible through the trees to the west and the previous two pairs to the east. I wondered if these clouds might have formed naturally, so I looked for any evidence of rolling turbulence which could hold them in such tight formation. That happens sometimes when a north-easterly brings long rolling clouds in over the Queensland coast. But I could see no indication of turbulence whatsoever. They just hung there in a non-turbulent layer of air that drifted slowly east toward Sydney.
About 50km to the east of my position and 2000ft closer to MSL, observer #2 was at the same time watching the earlier trails in the series as they passed over his house. They were somewhat dispersed but still held the same pattern of parallel pairs. By the time we discovered them they already covered at least 80km east to west, and we dare not guess the N-S spread. Can they be natural? I think the pairing discounts that possibility. So could they be con-trails?
They don’t line up with any commercial traffic that I’m aware of, but they did originate in the vicinity of Richmond Air Base. Even so, do con-trails behave like that? I watch any plane that leaves a trail, to see how long it takes to dissipate. Many trails from commercial jets don’t last 13 seconds. A few can take several minutes. How do dozens to hundreds of trails last (in their entirety, dispersed but not even partially dissipated/sublimated) for more than half a day, leaving a “white sky” in which additional con-trails freely dissipate or fail to form?

Slacko April 21
Aircraft are following a ground track while flying in a cross wind that is less than a 10th their speed. The contrail (water from the engine eflux freezing into ice crystals) left behind will drift – in the same way as clouds do, with the wind. 10 minutes later (a standard air traffic control separation) another aircraft follows the same air route and leaves a similar contrail. This may continue all day. The observer on the ground will see a series of evenly spaced contrails.with the space between them dependent on the wind speed.
Contrails only appear when the air at the aircraft level is sufficiently humid that the extra water added by the engine eflux does not evaporate despite its heat but condenses and freezes. If the humidity is just barely enough for contrails then the contrail forms then the ice crystals sublimate back to water vapor. This leads to what is called non-persistent contrails that form then fade. At the other end of the spectrum the water in the air at the contrail level may be supercooled but not condensing as there are no cloud condensation nucleii. A contrail forming in air with a lot of supercooled water vapor can be the trigger for the water to start condensing out. This is what is seen when the single contrail seems to grow into a thin layer of cirrus.
No such thing as chem trails.

MarkW

The humidity at the surface has nothing to do with humidity at altitude.
Secondly you have to understand the differences between the behavior of water droplets and ice crystals.
Sheesh, the unmitigated ignorance of some people.

James at 48

It’s ice, it’s 6 or more miles up. RH at the surface has nothing to do with contrails and what governs their formation and persistence.

JohnKnight

Each and every person who declares a negative with certainty in this realm, is either an imbecile or liar, as far as I’m concerned . .

MarkW

John, so you are really taking the position that unless someone can prove beyond a shadow of a doubt that the govt is doing things to the atmosphere via jet exhaust, you will continue to believe that they are?
And to think, you are calling others imbeciles.

JohnKnight

Readers, please consider carefully;
How could commenters here know with certainty that things for which there are (numerous) patents, and which are not illegal, have not been going on at all, I ask?

Menicholas

For all I know, when i leave the house for work, my two cats put on reading glasses and read War And Peace.
But I doubt it.
About as much as I doubt chem trails are anything more than a figment of some overactive imaginations.

JohnKnight

Well, apparently it won’t be long before you will know for certain it’s happening . . I mean the spraying, of course ; )

Slacko

Thanks Ian W for that explanation.

MarkW

Some people’s minds are so open that their brains have fallen out.
If I have this straight, according to John, everything that hasn’t been disproven conclusively, must be regarded as being true.

ozspeaksup

yeah and if their not chem theyre STILL pretty damn good at obscuring your skies.
your govt WAS using and on record for geoengineering way back since Vietnam days
just coming out of the closet partway I reckon.

Have their little minds ever considered that they might just tip us into an Ice Age? Whatever respect I might have perhaps had for US politicians and the Senate in particular has just vanished. When will this madness end?

RockyRoad

You give them more credit (“little minds”) than I would.
I wonder if they’ve considered the liability of their actions–how many $Trillions will this impact the world’s GDP if what they propose works, especially considering how devastating it could be.

David A

No worries, they will not actually do anything except spend five billion dollars researching, keeping the grants going and reinforcing with MONEY closed minds.

Menicholas

Just what I was thinking Alastair.
Pin-headed fools.
And what timing…just when we are likely about to undergo a period of natural cooling which may be quite dramatic.
So, given natural variation, how the hell will they know if what is done on purpose had any effect, and if so, how much?

JaKo

Too bad my lifespan would not allow me to laugh at all these nitwits when Earth plunges into the next ice age…

It’s the government … which means, there’s no limit to the amount of stupidity of which they are capable … and they still get paid on a regular basis, which is all they truly care about.

Peter Morris

So I was a kid in the 80s, and we read stories in our grammar books set in a future where the earth was colder because of all the aerosols. There was also one where the whole sky was so hazy kids didn’t even know what sunglasses were any more. There was also an episode of Superfriends where aliens had done the same to their planet and we’re trying to migrate to earth because it was warmer.
This story would be a lot funnier if it were as fictional as those I read and saw as a child.

John in Oz

and changing the albedo over the USA will have no effect (good or bad) on any other country. Trust us, we’re from the Government.

Just when you thought it couldn’t get any worse. When have we ever played with nature without unintended consequences?

Gamecock

Geoengineering: billions will die.

chris moffatt

If you read the statements of such as Maurice Strong you will find that this is the intent.

The statements of the anti-humanist population reduction crowd who designed the UN program aren’t PC here. One of the critical myths of the AGW-scam is that bigotry, emotional bias and censorship are attributes only of AGW-alarmists. Acknowledging that this is a political issue disguised as science is evidence of dissidence as serious as acknowledging that the sun controls earth’s climate.

Martin C

So, I wonder if Canada and Russia might sue the U.S if they tried this. Geez, I would WANT more warming where they are . . . 🙂

Roy Spencer

My thoughts, too. After Pinatubo, we know what happens.

Menicholas

Plus a bunch.

Gerry, England

I thought Canada now bought into the scam?

Tiburon

Here’s something OT, but refreshing (to me, anyway). An educational program about weather, climate and earth’s atmosphere, which, from the glossary, doesn’t seem to have a single mention of the demon gas! Or AGW or CAGW or climate change. Perhaps there’s hope for us, yet.
http://sisko.colorado.edu/FESD/MeetPresentFiles/2013.GEC.3.21.pdf

A few more Kracatoa or Pinatubo eruptions should do the trick.

Bryan A

Mt Aso would also function well in this regard and it appears to be waking up

Golden

The EPA wants to penalize you for creating particulates, the DOE want to spray particulates everywhere. The goal is to get tax payer funding with save the earth schemes. Someone should get funding to create dry ice to cool the earth, to balance the CO2 sequestration.

the lies they have been telling us for so long now have lost their minds and want to start the new ice age

Gary Pearse

The warming crowd is worrying about cooling happening anyway. They know that the “pause” was real – look what they did to get rid of it – they karlized it. The plummeting ENSO temperatures looks like they will have to add a lot more to warm the temperatures up. We will be back into 20 years with no warming if they let La Nina develop. I thought Ted Cruz headed up the Senate Sci and Tech committee? Oh, this is probably a Dem committee for something else. They want to ram through a train of items before the government changes and high on the agenda is to get something going so they can take credit for the cooling that they are worrying about.

The lies they have been telling us for so long now their plan is to start the next ice age!

emsnews

Actually, they keep telling us that the ideal conditions for us is exactly what was going on back during the Little Ice Age. We are supposedly wanting to have ice cover the oceans offshore of Delaware when Washington crossed during the Revolution.

Menicholas

Washington crossed the Delaware River, from Pennsylvania to Trenton, New Jersey, and attacked the Hessians unawares.
It was Christmastime, and the river was choked with ice, which rarely happens anymore and never so early.

@ G. Karst, The US ( as the USSR back in the days) gov has tried it for years going back decades. I have tried to find info regarding the efforts to use “cloud seeding” that caused flooding in the 50’s and 60’s there is no info on the net any longer.

DENNIS BIRD

We are 19 trillion in debt and now this. Is this real or is my matrix program completely messed up? Idiocracy is here.

Tiburon

well, technically, including unfunded liabilities like Medicare, Old Age Security, etc, speaking of the USA only – it’s more like 100 Trillion in debt.

RockyRoad

…and total world debt (both private and governmental) is said to be $710 Trillion. That’s 10 times the annual world GDP of ~$70 Trillion. Talk about unsustainable.

exSSNcrew

Correct. just look at http://www.usdebtclock.org

MarkW

Sander’s is promising to increase US spending by 50% and Hillary is not too far behind.
They are promising $10billion a year in new taxes.
First off the new taxes will only bring in half what is promised and even if it did, it would only cover a few percent all the new spending.
The question is no longer if will the US collapse, but how soon.

The particles produced by burning sulfur are droplets of sulfuric acid, mixed with water that they absorb from the atmosphere. These are not the solid particles of concern from coal fired lower plants.
Sulfuric acid forms from sulfur trioxide and water vapor. Sulfuric trioxide forms from sulfur dioxide reacting with some nitrogen oxides or ozone, but some is directly produced by burning sulfur.

benofhouston

Have you ever known what happens when SO3 reacts with H2O? Do them chemistry. That’s H2SO4, sulfuric acid.
The particulate is a different story, but considering the expense I go through annually to prove I have no sulfur emissions, a plan to release them en-mass is just plain insulting.

Bulldust

I remember reading about Intellectual Ventures in Superfreakonomics some years ago:

The problem with a “solution” like this is the lack of a government revenue stream…

Tiburon

those would be CO2. there are already regulations for everything else.

Robbie Depp

This doesn’t surprise me. When it actually cools, they’ll say they instituted the plan and claim it is working. The kool-aid drinkers will drink the kool-aid.

Gamecock

Therein lies the great risk. They will believe they know what they are doing, and proceed with even greater “adjustments” to the atmosphere. Incremental steps will give way to oblivion.

Manfred

Nothing could of course go wrong in a chaotic non-linear stochastic system in which the politics is settled and the science is politics. Crimes against humanity springs to mind.

David Sivyer

Beautifully said, Manfred!

James Fosser

I am quite satisfied with the albedo where I live in Australia so I do not want foreigners changing it thank you!

TimTheToolMan

I couldn’t agree more.

Gary Pearse

I had hoped Willis Eschenbach would have visited this thread to tell us what will happen if we partially block the sun with aerosols…..why, the clouds that form in the afternoon in the tropics will just form later and we will get the SAME amount of heating that we got before the geoprivateering experiment. Aw just give 1% of the 5.1B budget 50M!!! What in hell kind of experiment is going to cost 5B? I’m worried with 20trillion deficit that future government will only think in minimums of a few 10s of Billions.

Paul of Alexandria

Read Niven and Pournelle’s “Fallen Angels” (http://www.amazon.com/Fallen-Angels-Larry-Niven/dp/0743471814/ref=sr_1_fkmr0_1?s=books&ie=UTF8&qid=1461296339&sr=1-1-fkmr0&keywords=Niven+Poirnelle%27s+fallen+angel ) to find out where this is going!
(Greens take over and “clean up the air”; turns out that CO2 was the only thing holding back the next ice age.)

Menicholas

Except that for this to be true, CO2 would have to be having some large effect on the temp of the Earth.
Which the near twenty year pause, during a time when atmospheric CO2 increased by more than ever, would seem to disprove.
We may not need any “cleaned up air” to see a harmful cooling trend, and “cleaning up the air” may have no effect on climate, but will almost certainly have a huge toll on human lives, comfort, and prosperity.
Worldwide depression, widespread famines, massive depopulation via starvation, and a near total economic collapse sound appealing?
Not to this kid it don’t.

James Fosser

Excellent idea. Once the albedo is changed above the US then the rest of the 7 billion people on Earth can watch how this changes the CO2 around the 323 million in the US and perhaps conduct the same experiment to change the albedo above their location. Perhaps the odd cantankerous person or so might choose to keep the albedo above their house as it is!

Slacko

It’s naive to single out the US. Every place on earth where the US has allies and/or military bases is already inundated with the subject of this thread. They know the world is beginning to cool and they need either to be able to say “Look, we did it” or “See, we told you it would get warmer.”

Those whom the gods would destroy, they first make mad.
We are there.

Ed Zuiderwijk

Given that climate “forcing” by CO2 is much less than these fools think it is, any scheme of this kind, if it were successful, will drive the climate system into an ice age.

James Francisco

Not to worry Ed. If their plan does go overboard and cools to much they can just drag out an old scheme they came up with during the 1970s next ice age scare. It was to add carbon black to the polar ice to reduce the reflected energy. Should cost no more than 5 billion to study.

Makes me wonder if any of these chem trail peeps have a pilots license, or enough money to rent a private jet and go up and take some samples.
I think the answer must be no to both questions.

commieBob

Contrails affect albedo. The evidence is that they affect the temperature difference between day and night rather than the average. ie. They don’t make it cooler overall. link link
Do the proponents of the Albedo Modification Geoengineering Proposal give any evidence that their results would be different?

“Do the proponents of the Albedo Modification Geoengineering Proposal give any evidence that their results would be different?”
They just need $5.4 billion. They’ll get what ever evidence they pay for.

Your taxpayer at waste…er…work!

Greg

Without getting into wacko chemtrail speculation, airliners burn kerosene which, amongst other things, contains sulphur. When burnt it will produce sulphate aerosols and like vehicle engines lots of small particulates.
The planes spend most of their time cruising in the lower stratosphere, just above much of the visible cloud cover near the tropopause.
If atmospheric conditions are close to the point where condensation into cloud will happen, the presence of these pollutants ( which act as condensation nuclei ) will cause an increase in cloud. So yes there are trails of chemicals released by commercial aircraft that on some days will lead to persistent and even spreading light cloud.
The experiment is already in place, all we need to do is measure it.
We also have data from the last two major statratospheric eruptions showing what climate reaction to a massive injection of sulphate aerosols in the stratosphere is :comment image
https://climategrog.wordpress.com/uah_tls_365d/
Note the blowback: after the initial disturbance the has cleared the stratosphere cools, permanently, indicating that is more transparent or ‘clearer’ that it was beforehand.
What any such experiment is likely to do is CAUSE EVEN MORE GLOBAL WARMING at the surface.
Now before we start playing at being the sorcerer’s apprentice we’d better make sure that there is even a problem that needs addressing.
So far it looks like the warming that happened between 1975 and 1997 was probably due to volcanoes now AGW, if the “well-organised multi-billion dollar campaign of dis-information” that has hijacked climatology would get of their butts and do some real science instead of spewing out an endless stream of spurious correlations and projections from defective climate models, maybe we would have a better understanding.

Greg

sorry: “volcanoes, not AGW”

@ Greg, 11:17, April 21. I will never forget the 2 days after 911, no air traffic for 2-3 days, the sky was clear and I kid thee not, we had birds sit our laps as if they were saying thanks for no noise/pollution etc. I have pics of a blue stellar jay eating out of my hand. never happened before or since we live rural and have animals around us all the time but that had never happened to us before or since.

Too bad the airports resumed flights. You could have had the birds make you a dress so you could go to the Ball with your stepsisters. I’m hungry, can somebody pass me a slice of unicorn?

Greg

Yes, the birds must have felt in instant benefit from the reduction in all that CO2 “pollution” , no wonder they were happy.
A study did find stronger incoming radiation on those days. Sadly there was not control for how much of that was due to weather variability, so it remained inconclusive.

Gamecock

‘So yes there are trails of chemicals released by commercial aircraft’

Worse still…it won’t wash off!

AndyE

A little learning is a dangerous thing – the children’s story about the Sorcerer’s apprentice comes to my mind. And would the Americans really have the gall to try it out without the rest of us agreeing to it??

David Chappell

Unhappily, the answer to your question is “Yes”.

seifred

Seems a better solution might be to tax global warming zealots according to their degree of green nutdom… If taxing stuff leads to less of it, that would be a win for common sense.

Elmer

Pretty sure we’re already doing this.

Marcus

…Mother Nature will not be impressed !

Didn’t we use to do this with manufacturing in the 70’s? Wasn’t all the noise back then about aerosols killing us? Didn’t we talk about acid rain and create EPA regulation to clean up the air with mass particulate reduction?

Environmentalism starts with you – so the greens tell us, and they are right – each of us should play our part. What I propose may sound “politically incorrect” but no disrespect is intended, so please bear with me.
Geoengineering solutions might come from an unlikely sourse – the late pop legend Michael Jackson. He made a bold individual contribution to lowering albedo, by whitening the color of his own skin.
The POTUS himself should consider doing something similar, to back up his green rhetoric by making a personal contribution to increasing global albedo.
Citizens of the UK could likewise banish their unfortunate reputation for poor dental hygiene, and get busy chemically whitening their teeth, following the example of their environmentally responsible North American cousins. When it comes to green – or green whiteness – we all have our own part to play.

commieBob

The parts of the body that are exposed really aren’t enough. If we follow your line of thinking, we would all have to go around naked to maximize our albedo enhancingness. We also should dye our hair silver.

He made a bold individual contribution to lowering albedo …

Actually, you have it backwards. More albedo means more reflection so Jackson raised his albedo.

MarkW

Just have everyone wear white shirts.

MarkW

But not before labor day.

sophocles

huh? There’s actually some ozone layer left and they want to kill that too?

Greg

Yes ozone is part of the equation too. NASA estimate the stratospheric ozone dropped by 5-8% after Pinatubo, presumably the same thing happened after El Chichon. Nothing to do with CFCs.
Much of the drop in TLS I showed above was due to ozone depletion.
This current idea is so screwed up it should be laughed at. The most likely result would be even more global warming as happened as a result of the those volcanoes. They will then say OMG , AGW is worse than we thought we need to do even more “corrective measures”. This will continue until they reach a tipping point and trigger the next glaciation.
