"A group of scientists from universities in the United States, the United Kingdom, and Australia have released a new study calling for geoengineering of the climate in order to save the coral reefs from a process known as "bleaching."

The researchers, including authors from the Carnegie Institution for Science, the University of Exeter, the Met Office Hadley Centre and the University of Queensland, call for geoengineering the climate using a practice known as Solar Radiation Management (SRM). This involves spraying aerosols from planes in an attempt to reflect the sun's light with the purpose of preventing rising sea surface temperatures.'

" The conclusions drawn from this body of work, which applied widely used algorithms to estimate coral bleaching8, are that we must either accept that the loss of a large percentage of the world's coral reefs is inevitable, or consider technological solutions to buy those reefs time until atmospheric CO2 concentrations can be reduced"

"Even if the world were to cut emissions to zero tomorrow, global temperatures and sea levels would rise for decades. If our roll of the climate dice is unlucky, they could rise for centuries. It is in this context that some climate researchers have begun to reluctantly take seriously ideas first proposed in the 1960s: the possibility of using solar geoengineering to help restore the world's climate, alongside aggressive actions to reduce greenhouse-gas (GHG) emissions to zero and below.

Fear of solar geoengineering is entirely healthy. Its mere prospect might be hyped by fossil fuel interests to thwart emissions cuts. It could be used by one or a few nations in a way that's harmful to many. There might be some yet undiscovered risk making the technology much less effective in reality than the largely positive story told by computer models.

So, back in the 60's and 70's? Aerosols were bad, they messed with the ozones (little guys that lived in Antarctica?)

It turns out that the Aerosols were reflecting heat back into space and preventing global warming.

BUT Aerosols were outlawed and then global iceage possibilities turned into global warming and the 'Climate' started to heat up very fast.

Then, luckily, China and India started ramping up production and started burning coal at ever increasing rates and their pollution has slowed the 'Global warming' to the point that they now call it 'climate change' instead of Global warming.

NOW Scientist are saying what? that maybe we should have left the aerosols alone 40 years ago and we might not be in this fix?

Or they are saying that we need to start using Aerosols again?

Instead of flying planes to dump aerosols, why not just bring back aerosol deoderant, and get rid of catalitic converters??? We get back to the good old days when we already chemically kept the Global weather in check?

 

-------------------------

None of that makes much sense so I won't try beyond this:

The ozone layer was being destroyed by chlorofluorocarbons, they have been banned, problem is slowly going away.

problem is slowly going away.

 

 

AND...  Mother earth is now in a warming trend...

-------------------------

I think maybe you got confused by the word , aerosol which is just a delivery mechanism that was used for CFCs, not a particular chemical

We fixed the chlorofluorocarbon/ozone problem with legislation banning them in the 70s, CFCs have a lifetime in the atmosphere of about 20 to 100 years so the effect of the ban is just starting to take hold, that's why the problem is slowly going away.

We know that humans not "mother nature" are warming the earth with C02 emissions and that's a much bigger problem to fix, and with more far reaching and longer term consequences if we do not.

These risky geoengineering schemes are starting to gain some traction as some scientist realize that our political system is failing to fix the carbon emission problem.

Trump's idiotic action regarding coal yesterday brought that truth home to some.

somebody else sounds like the chick at the open referendum on sand dumping I attended.  She said, "the fish can just swim away and live somewhere else."  Similar to that one comment on sand per Sam Kinison.  Well, one thing is true, somebodyelse will go way. 

One specific family of compounds affecting stratospheric ozone.

Particulates, sulfates, and such in the lower troposphere. These were causing things like acid rain, smog, atmospheric depositon of nitrogen, formation of ground level ozone which is a nasty chemical in the breathing region of the atmosphere despite its benefit when way up in the stratosphere.

 

Something different than what is rattling around in your head.

WTF?

"somebody else sounds like the chick at the open referendum" 

I relish the inevitable moment when 

manatee poop is brought up 

in public meetings concerning IRL water quality.

Um, like I heard that ozone was like good because it blocks the sun and stuff and keeps people from getting cancer and we shouldn't use hairspay or air conditioning to save the ozone. Now you are telling us that ozone is bad because we shouldn't breath it or anything. If ozone is bad should we like use more hair spray and air conditioning and stuff so there would be less ozone? You scientologists should make up your minds already if you are so smart.

back on subject,

(and being a space geek)

I always liked this idea

plus it doesn't further muck up the atmosphere

Particulates, sulfates, and such in the lower troposphere. These were causing things like acid rain, smog, atmospheric depositon of nitrogen, formation of ground level ozone which is a nasty chemical in the breathing region of the atmosphere despite its benefit when way up in the stratosphere.

 

We believe because we were told to believe that humans not "mother nature" are warming the earth with C02 emissions and that's a much bigger problem to fix, and with more far reaching and longer term consequences if we do not.

 

We know that humans not "mother nature" WERE cooling the earth with aerosols and Particulates and Sulfates which reflect the sunlight back into space.

 

The period between when America and Europe STOPPED aerosols and Stopped Particulates, sulfates, and such and the period when China and India started mass production and ramping up their industry. WAS A WARMING PERIOD where it was believed that humans not "mother nature" were warming the earth with C02 emissions.

It turns out that humans WERE actually cooling the earth with aerosols and Particulates and Sulfates and when they stopped aerosols and Particulates and sulfates then the earth continued its natural warming trend that has been going on for thousands of years.

The evidence that this is true is the trend quoted by climate change deniers that the level of warming has leveled off, the same time period that China and India’s use of carbon fuels has been increasing.

Somebody should quit when he's ahead.

In that case, I sure as hell don't want to pay for it. We had to deal with what previous generations left us, and so shall future generations with respect to what we do. That's the way it works.

Why don't you guys put all your money together and do this. Hell, if all of you had just used the money you flushed down the toilet in recent political campaigns, you'd already have 100's of millions for this project. Given that, it seems that you true believers don't want to spend your own money to realize your goals. Instead you want to get politicians to get other people to pay for your goals. In light of this grand failure to put your own money where your mouths are, I remain skeptical about your dedication to the stated cause. And I am not alone. If you haven't noticed, we working people have grown tired of paying for progs' crazy schemes. Trump, therefore, is cutting them down to size. We voted specifically for that and we are applauding him for doing so.

So, anyway, put up your own money and stop trying to coerce us into paying for you. If you do so, the rest of us will be happy to observe your efforts with interest.

Comrade Tpaulapov, put away the ice skates this weekend, the triple toe loops and sowcows can wait.

I hope you have "the courage and vision" to break out the redwood plank and speedos and hit the "breakers" at the pier.

The Easter recess chicks dig the speedos.

The problems left to us by our parents are dwarfed by the magnitude of this one.
Trumps idiocy is increasing the bill due.

I think these sort of grandiose geoengineering schemes are silly and likely to have feedbacks that cost us even more.

The easier solution, the one that costs far less, (unless you are a billionaire that owns a lot of carbon in the ground) the solution that actually pays for itself with a growing economy is to rapidly move away from a carbon energy based economy. To invest in clean energy.

But half of the public is still seduced by the big lie, we are running out of time so it's looking like our kids will have to pay for our screwed up politics.
