This short article argues that there is strong reason to be skeptical of CO2 storage being able to be done at the scale really required to be effective:
The Climate Panel sees CCS as offering great potential. In various scenarios it accounts for between 15 and 55 percent of the reduction of greenhouse gases by 2100...The problem is, according to Anders Hansson, that CCS is still a relatively untested method.
“There are a number of small facilities, in Norway, for instance, where they capture and store a million tons of carbon dioxide per year. Swedish Vattenfall is starting a pilot facility in eastern German this summer.”
Globally, a total of some millions of tons per year is being stored today within the framework of CCS. But to live up to the hopes placed on CCS requires the storage of several billion tons. In other words, this involves gargantuan volumes. In fact, carbon dioxide would be the world’s largest transported good.
“In full scale this technology only exists in the imaginations of the people developing it,” says Anders Hansson. “It’s overly optimistic to place such great faith in it, considering all the uncertainties found in the scientific literature.”

The earth is cooling. It stopped warming 10 years ago. The warmest year was 1934. The last 16 months have seen a significant drop in temperatures. The oceans have cooled. Time to look at sunspots and the fact that cycle 24 has not developed.
