From the European Association of Geochemistry | Wally Broeker, the first person to alert the world to Global Warming, has called for atmospheric CO2 to be captured and stored underground. He says that Carbon Capture, combined with limits on fossil fuel emissions, is the best way to avoid global warming getting out of control over the next fifty years. Professor Broeker (Columbia University, New York) made the call during his presentation to the International Carbon Conference in Reykjavik, Iceland, where 150 scientists are meeting to discuss Carbon Capture and Storage.
He was presenting an analysis which showed that the world has been cooling very slowly, over the last 51 million years, but that human activity is causing a rise in temperature which will lead to problems over the next 100,000 years.
“We have painted ourselves into a tight corner. We can’t reduce our reliance of fossil fuels quickly enough, so we need to look at alternatives.
“One of the best ways to deal with this is likely to be carbon capture – in other words, putting the carbon back where it came from, underground. There has been great progress in capturing carbon from industrial processes, but to really make a difference we need to begin to capture atmospheric CO2. Ideally, we could reach a stage where we could control the levels of CO2 in the atmosphere, like you control your central heating. Continually increasing CO2 levels means that we will need to actively manage CO2 levels in the environment, not just stop more being produced. The technology is proven, it just needs to be brought to a stage where it can be implemented.
Wally Broeker was speaking at the International Carbon Conference in Reykjavik, where 150 scientists are meeting to discuss how best CO2 can be removed from the atmosphere as part of a programme to reduce global warming.
Meeting co-convener Professor Eric Oelkers (University College London and University of Toulouse) commented:
“Capture is now at a crossroads; we have proven methods to store carbon in the Earth but are limited in our ability to capture this carbon directly from the atmosphere. We are very good at capturing carbon from factories and power stations, but because roughly two-thirds of our carbon originates from disperse sources, implementing direct air capture is key to solving this global challenge”.
The international Carbon Conference takes place in Reykjavik, Iceland, from 25-29 August 2014. Conference website, https://www.or.is/en/projects/international-carbon-conference-2014

He’ll have to overcome reality though, and the reality is that these schemes have failed, in what was called in the U.K. as “descending into farce” sort of like the Edsel
“The debate is false. One of the main drivers of ice ages was the CO2 content in the air. When the CO2 was lower it got plenty colder. So, as we add CO2 it’s going to get a lot warmer.

Shawn,
Please you did not just say that.
Where is the warming for the last 17 plus years?
C02 kept rising feeding millions and greening the earth.
Deserts are shrinking.
Anyway warming is also good depending on where you live.
Tell people in Siberia its too hot and I think they will take the thermostat control away from you.

No no. When CO2 was at its lowest point it got warmer, much warmer.

“…. but that human activity is causing a rise in temperature which will lead to problems over the next 100,000 years.”
This is the most sensible timescale I’ve heard about AGW problem.
So if we are not into a new glacial in, let’s say, 20,000 years time and human civilisation still exists ( most unlikely ) lets have another look at CCS.
That’s it Shawn and Greg. In a nutshell. You got it. Pass it on.
I think before to long these nutters will need some very big holes in the ground…. To hide in from lots of very angry people who have payed loads of money to no result!

“They call me a ‘junk scientist’ to my face,” he says.
Nevertheless, he insists, “The debate is false. One of the main drivers of ice ages was the CO2 content in the air. When the CO2 was lower it got plenty colder. So, as we add CO2 it’s going to get a lot warmer.

Oh what? The Al Gore ‘inconvenient’ fallacy all over again.
From someone who has spent his life working paleo that can be nothing more than deliberate misdirection. And he wonders why he gets labelled a ‘junk scientist’?
“One of the best ways to deal with this is likely to be carbon capture – in other words, putting the carbon back where it came from, underground.”
NO! It actually came from the atmosphere. Geological and biological processes have been stripping CO2 from the atmosphere and locking up in rocks – limestone, dolomite, chalk, shale, in fact, all calcareous rocks – for literally eons. Fossil fuels are puny by comparison. Atmospheric CO2 is in fact at extremely LOW levels on geological time scales. Any lower and it will become critical for plant life.
What an idiot this Broecker is.
And now we know how all those “fossil fuels” were created. Dinosaurs simply channeled CO2 underground. Could be that’s the real reason they went extinct since they eliminated their food source (CO2)?
I have not read the comments, or the article, but nature has found the solution, namely trees, plants and vegetation.
If people want carbon capture, just plant some forests on scrub land. Preferably trees that have a long life expectancy.
Sequester the carbonloon “scientists”. Problem solved.
I didn’t know you could gain a professorship in suicidal idiocy. Are they giving them away in boxes of Fruit Loops?
Whacky loons like these guys don’t seem to understand the basic tenets of chemical thermodynamics.
While burning the carbon fuels that produces CO2 liberates the energy society needs, reversing the process to pull carbon from CO2 so we can bury it requires the same energy that was liberated in the first place.
Obviously he understands nothing about the mechanics and limitations of carbon sequestration.
[snip – over the top, but funny -mod]
Closing comments are nearly complete.
The conference is about to come to a close. All goals and objectives (I trust) have been met.
Time to fire up those big jet engines and head off to the next International Climate Summit To Save The Planet from “Atmospheric Anthropogenic Carbon Dioxide Driven Catastrophic Global Climate Disruption”.
I think airspace over Iceland is closed due to the volcanic eruption. With luck it will last months and these idiots can “cool their jets”, literally.
“He was presenting an analysis which showed that the world has been cooling very slowly, over the last 51 million years, but that human activity is causing a rise in temperature which will lead to problems over the next 100,000 years.”
Ive tried telling this first part to people I debate this with. If we actually do have the power to raise the earths temp, we very well might save not destroy the earths balance. This planet is slowly freezing to death.
How to take CO2 out of the atmosphere and store it in the ground:
1. Mine coal. This creates huge cavities in the ground.
2. Burn the coal. This releases CO2 to the atmpsphere.
3. Plant trees. This takes CO2 out of the atmosphere.
4. Use the trees for two things
4a: Building materials. This keeps the CO2 out of the atmosphere for a very, very long time.
4b: Paper
5. Take waste paper and waste wood and pulp them into slurry, then using tech much like “rammed earth” construction, pack this slurry into the cavities created by coal mines. This puts the carbon right back where it came from and pound for pound at likely a higher carbon content than what came out. In fact, you might be able to increase that carbon content even more by pre-processing or “burning” that pulp and burying the ash only.
6. Under no circumstances recycle paper / wood. Recycling paper results in fewer trees being farmed to produce paper and actually reduces the amount of CO2 taken out of the atmosphere. But tossing paper into conventional landfills increases the rate at which they fill up. So — use the great big cavities we have created from mines. Fill them back up with the carbon we took out.
Broeker is a respected climate scientist but his advocacy of CAGW is disconnected to his scientific works. None of his works provide solid evidence for CAGW. But by making silly statements like the climate beast, his research gets funded. As Lindzen once said if you want to study cockroaches, link it to climate change and you will get funding.
An early CAGW warmist discredits himself, without help, and reveals his own nuttiness.
