The Intergovernmental Panel on Climate Change based the claims on an unpublished report that had not been subjected to routine scientific scrutiny - and ignored warnings from scientific advisers. The report's author later withdrew the claim because the evidence was too weak.
The link was central to demands at last month's Copenhagen climate summit by African nations for compensation of $US100 billion from the rich nations.
However, the IPCC knew in 2008 that the link could not be proved but did not alert world leaders, who have used weather extremes to bolster the case for action on climate change.
And the world leaders have been spewing the unsubstantiated claims.
PM Kevin Rudd- ""We will feel the effects of climate change fastest and hardest, and therefore we must act this week, and the government will be doing everything possible to make sure that can occur,"
US President Barack Obama- "More powerful storms and floods threaten every continent."
What is that saying about lies? There are 3 kinds of lies. Lies, Dam Lies and Statistics.
