What is the world coming to? The chairman of Shell Oil, Ron Oxburgh, is admitting that the threat of climate change makes him really very worried for the planet. Article at Guardian. He in part talks about how we urgently need to capture the emissions of the greenhouse gas carbon dioxide, probably a major contributor to global warming, and store it underground, a technique which is called carbon sequestration.
"Sequestration is difficult, but if we don't have sequestration then I see very little hope for the world."
Does he really care, or is he just voicing his support for something that probably isn't going to happen anyway? I don't know. Shell is indeed a company that invests quite a bit in alternative energy sources. Do they do that just to hedge their bets, or are they willing to do something to guide things in a different direction?
"No one can be comfortable at the prospect of continuing to pump out the amounts of carbon dioxide that we are pumping out at present ... with consequences that we really can't predict but are probably not good."
"You probably have to put it under the sea but there are other possibilities. You may be able to trap it in solids or something like that."
"The timescale might be impossible, in which case I'm really very worried for the planet because I don't see any other approach."
