No matter what side you happen to fall on when it comes to global warming; whether you ascribe to Ian Plimer’s claim:
Over the past 250 years, humans have added just one part of CO2 in 10,000 to the atmosphere. One volcanic cough can do this in a day.
Or whether you ascribe to Open Mind, this is a clever ad that makes me want to swim in search of submerged cities. They’re down there, at the bottom of lakes and oceans, waiting to be found.
