Proponents of the proposed Great Engineering Feat of Carbon Capture and Storage, portray their heroic efforts to suck Carbon Dioxide out of industrial processes, and even out of the sky itself, as the last chance to save us from ourselves and our untidy emissions.
Thing is, even if all the extra Carbon Dioxide in the Atmosphere from the last 150 years of human Fossil Fuel burning activities could be swallowed down into rocks, filters, artificial trees, real trees and caves, all at once, when we have invented and fully developed the Geoengineering Technology for it, we would still have a globally warmed world, and still plenty of excess Carbon Dioxide in the Oceans and Land, which can still make its way out into the Atmosphere…
The enduring challenge is that we must curtail and rein in Carbon Dioxide emissions, as soon as possible, starting now. We cannot carry on burning and wait for Carbon-sucking technological marvels, that may never materialise, as Ken Caldeira and his research colleague Long Cao demonstrate :-

It looks like The Guardian newspaper has been infected with Global Warming scepticism.
I thought the paper was supposed to have some decent editorial process on Science ! But, sadly, clearly, not.
Here are the main problems with the article :-
1. The author does not understand the processes that govern the accumulation of Carbon Dioxide in the Atmosphere.
2. The author appears to have no knowledge of how the Earth system as a whole regulated Carbon Dioxide in the Atmosphere in the distant past within certain limits of extent.
3. The author does not recognise that the current level of Carbon Dioxide in the Atmosphere is much higher than in the distant past. Neither does he offer any explanation for why the level should have strayed outside the long-term boundaries.
4. The author accepts that periods of Earth History with more Carbon Dioxide in the Atmosphere were warmer than periods with less Carbon Dioxide, but fails to offer a possible mechanism that could draw down Carbon Dioxide from the Atmosphere now to the regulated boundaries of the distant past.
5. The author does not appear to appreciate that the Younger Dryas cooling event was almost certainly entirely unrelated to Carbon Dioxide levels in the Atmosphere.
6. The author does not appear to appreciate that the Younger Dryas cooling event was not global in scope. Or rather, although there are records of effects almost universally, the effects were not the same everywhere.
7. The author does not recount the extreme warming that ended the Younger Dryas event.
Which is what you would expect, since the main cause of the Younger Dryas event was not the level of Carbon Dioxide in the Atmosphere; and naturally, the levels of Carbon Dioxide still in the Atmosphere caused the temperatures to return to where they were prior to the Younger Dryas cooling event.
The author of the article appears to be a software engineer with an education in biological sciences. I doubt he has ever taken a course in Global Warming Science. I suggest he should. It’s all online if he wants it. Here are David Archer’s lecture videos from the University of Chicago :-

The idea behind “clean development” is simple : promoting the clean development of developing countries so that they don’t make the same dirty development mistakes that the developed countries did when they were developing.
So, let the developing countries develop, but avoid the dirty part. Instead of burning Coal to make electricity, let them burn Natural Gas, or BioMethane (poo power); or let them make wind turbines, and hydropower dams and efficient biomass stoves.
There was to be a fund to finance Clean Development Mechanism projects, and it was supposed to be aimed at developing countries.
However, the negotiations around the CDM have taken more than one twist. Today, discussions were held about whether to permit Carbon Capture and Storage technologies to be included as “clean development”.

It’s proving to be a bad year for Greenhouse Gas control and Polar Ice integrity.
Despite the drop in production of the Developed Economies, due to the downturn/recession, Carbon Dioxide (CO2) levels in the atmosphere carried on rising :-
