When Sir Crispin Tickell had the temerity to suggest that “the business community needs to re-examine the fundamentals of economics” at the recent World Business Summit on Climate Change in Copenhagen, his discordant tone was drowned out by a chorus of more than 800 delegates singing the praises of unfettered markets as a means to tackle climate change.

The commitment to carry on with business as usual took an almost surreal form at times. Indra Nooyi, the chief executive officer of PepsiCo, proudly proclaimed: “The fact that I flew here for 1 1/2 hours to sit on a panel them I’m flying straight back to the US is an example of our commitment to environmental sustainability.”

More worryingly, plans for low-carbon technology give the expansion of high-carbon coal power pride of place. The promotional rhetoric is of Carbon Capture and Storage [CCS background guide], yet those from the power sector are blunt about its shortcomings. “One of the plants we are building is CCS ready, although to be quite frank no one really knows what that is at the moment,” claimed Steve Lennon, managing director of South Africa’s Eskom.

CLIMATE change is turning the oceans more acid in a trend that could endanger everything from clams to coral and be irreversible for thousands of years.

Seventy academies from around the world urged governments meeting in Bonn for climate talks from June 1-12 to take more account of risks to the oceans in a new UN treaty for fighting global warming due to be agreed in Copenhagen in December.

The academies said rising amounts of carbon dioxide, the main greenhouse gas emitted mainly by human use of fossil fuels, were being absorbed by the oceans and making it harder for creatures to build protective body parts.
