Can We Offset Global Warming By Geoengineering The Climate With Aerosols?

Can We Offset Global Warming By Geoengineering The Climate With Aerosols?

ScienceDaily (Feb. 17, 2008) — Concerned that energy system transformations are proceeding too slowly to avoid risks from dangerous human-induced climate change, many scientists are wondering whether geoengineering (the deliberate change of the Earth's climate) may help counteract global warming.

Sulfate aerosols, commonly released by volcanoes, serve to scatter incoming solar energy in the stratosphere, preventing it from reaching the surface. To investigate the feasibility of deliberately mimicking the effect of volcanic aerosols, Rasch et al. explore scenarios in which aerosol properties are varied to assess interactions with the climate system.

Through model simulations, they discover that, because stratosphere-troposphere exchange processes change with increasing levels of aerosols, about 50 percent more aerosols would have to be injected into the atmosphere than in the scenario where such processes stayed constant.

Further, almost double the level of aerosol loading is required to counteract greenhouse warming if aerosol particles are as large as those seen during volcanic eruptions. The authors caution that geoengineering methods to mask global warming may have serious environmental consequences that must be explored before any action is taken.

Burning trash to save the planet makes as much sense as anything algore has said.

We might counter sea level rise by directing ocean “overflow” into below sea-level areas like Death Valley.

These dolts definitely don't understand what this is all about. The United Nations and the IPCC aren't interested in fixing "Global Warming" They are interested in political power and need an Emmanuel Goldstein to maintain it. "Global Warming" fills that need.

That’s correct. GW has nothing to do with science, but with morality and the constant reference to consensus is a dead giveaway of the scheme.

Ironic, isn’t it? We pass laws forcing the companies who are belching smoke and particulates from their smokestacks to clean them up and come to find out that they were preventing globull warming!

So, in effect, globull warming is the GREENIES’ FAULT!

My theory was legalizing CFC’s again and opening up those ozone holes again. Makes as much sense.

“We pass laws forcing the companies who are belching smoke and particulates from their smokestacks to clean them up”

It has always amazed me that the greatest polluters in history of the world have been the Communist/Marxist paradises of the Soviet Union and China. Now only a Marxist/Communist solution will work for Global Warming. But you are totally correct we need to remove every scrubber on every smokestack in the US of A.

You don’t need to read the article you are doing the “globally correct” thing. According to the article your particulates from the wood fire will counteract global warming. Truly you are an enlightened one.

I wonder if these idiots have seen the last episode of "Dinosaurs", where the dinos set off nuclear explosions in volcanoes to "warm the planet", instead, they induce a "nuclear winter" scenario, at or around 63 million BC....

And all this time, we thought an asteroid did it....

I also own a diesel pickup, that belches lots of black smoke when I pull away from stop lights....(So far, I've "smoked" dozens of mini-vans and 2 city cops....)

I could turn up the fuel a little more, but at $3.20/gal., I'll need a second job....

“own a diesel pickup”

I have an F-150 gas. I wonder how hard it would be to have an oil injector in the exhaust manifold to produce the needed smoke to combat GW? You know I just feel I need to keep-up-with-the-Jones’.

"I have an F-150 gas. I wonder how hard it would be to have an oil injector in the exhaust manifold "

A kid I knew years ago in high school had a small pump to pump oil into his carburetor at the flip of a switch. A "smoke screen" ala James Bond.

Definitely a man ahead of his time.

The earth is warming but not to the degree that Global Warming idealist portray.

What is happening is Biblical though,

Revelations 16:

"8": And the fourth angel poured out his vial upon the sun; and power was given unto him to scorch men with fire. "9": And men were scorched with great heat, and blasphemed the name of God, which hath power over these plagues: and they repented not to give him glory.

Install a second windshield-washer tank w/pump under your hood, routing a hose to a point just before the throttle body.

Use a light weight oil (maybe even cooking oil), and just experiment with oil weight/engine speed/throttle setting combos for maximum effect.

Some diesel tractors/trucks come with a device that sprays ether into the intake for cold morning starts. One of those, with a can of WD-40 or carb cleaner produces tons of white smoke. Check with a tractor dealer for one of these things. I know that International Harvester had them on their tractors back in the 60’s and 70’s.

NAPA may be a good try, too, they have lots of “fun” stuff....

I equate this passage with the scenario that astronomers predict will happen when the sun uses up it's supply of hydrogen and starts to fuse helium atoms....

They say it will become a "Red Dwarf" star, and grow in size from it's present diameter of 1 million miles to approx. 40-100 million miles. At that diameter, the planets Mercury and Venus will be incinerated, and Earth, if it isn't fried outright, will be nothing more than a cinder....

“The authors caution that geoengineering methods to mask global warming may have serious environmental consequences that must be explored before any action is taken.”

But we don`t have time to explore the consquences. The planet is dying and action must be taken now!!! Reminds me of the proposals scientists made in the `70s to melt the North Pole to prevent an onrushing ice age. And now we are destroying rainforests in an effort to “save” the earth and it`s biosphere. (bio-fuels) What really frightens is that the ever increasing hysteria over a half-a-degree temperature rise over a hundred years is going to force taking ever increasing drastic actions. Then we will REALLY screw things up.
