You’d have to have a heart as cold as the pre-globally-warmed Arctic not to be howling with laughter at this, from The Guardian:
One senior figure suggested there may be faults with up to 20% of the carbon credits – known as certified emissions reductions – already sold. Since these are used by European governments and corporations to justify increases in emissions, the effect is that in some cases malpractice at the CDM has added to the net amount of greenhouse gas in the atmosphere.
I wouldn’t be surprised if Katrina was triggered by Al Gore’s carbon offsets.
