The world’s top scientists are gathering in Copenhagen this week with momentous news. You are unlikely to hear much from the big news outlets (the future of civilization’s got nothing on Brangelina after all) but the conference is expected to confirm what has been obvious since at least 2007: that global warming is happening much more quickly than predicted.

The gold standard for policy-makers has long been the UN’s Intergovernmental Panel on Climate Change (IPCC). The IPCC summarizes the research of literally thousands of researchers and provides governments with the best available summary of climate science.

But the process has a major flaw — by the time all the science is collected and synthesized, by the time the IPCC gets the reports written, by the time the world’s governments vet the summaries for public release…by the time you or I get to read the IPCC reports, they are summarizing research that is several years old.

The last IPCC report was a bombshell kicking off an international flurry of public awareness and a newfound interest in all things “green.” But it was also widely acknowledged to be very conservative in its predictions, not taking into account up-to-date information such as the rate of permafrost thaw or Arctic melt. As Canadians know, these are massive changes which make predictions much more dire than the predictions the average global citizen would have heard. For example, sea level rise measured in metres, not the centimeters previously published, and temperature rise on the order of 5 or 6 degrees (2 degrees had been seen as the danger threshold).

So, in an unprecedented move,  the world’s top climate scientists are gathering in Copenhagen to make sure that the next round of international negotiations acts urgently on the best data available. Those negotiations are scheduled to finalize at Copenhagen in December of this year.

The scientific community is doing all they can to alert the world of the looming catastrophe. But the solutions have to come from political leaders — and they are accountable to the public, not scientists. Over to us….

Acidic seas fuel extinction fears

By BBC Environment analyst Roger Harrabin

Here are some of the frightening findings described:

• Since the Industrial Revolution, CO2 emissions have already turned the sea about 30% more acidic.
• The World’s oceans are more acidic now than they have been for at least 500,000 years, they add.
• Up to 50% of the CO2 released by burning fossil fuels over the past 200 years has been absorbed by world’s oceans.

In this story, top ocean scientist Dr Carol Turley from Plymouth Marine Laboratory says,

“I believe we may be heading for a mass extinction, as the rate of change in the oceans hasn’t been seen since the dinosaurs. It may have a major impact on food security. It really is imperative that we cut emissions of CO2.”

(Dr Turley is presently in Copenhagen chairing a panel on ocean acidification.)
