To Al Gore, Barack Obama isn't up to the job of tackling climate change. In fact, Gore thinks Obama is no better than Big Oil's favourite pres, George w. Bush.
Mr Gore said that in the face of attacks from fossil-fuel industries and denial and delay from Republicans in Congress, Mr Obama had failed to act decisively to alter the nation's policies on climate change and energy.
Addressing climate change on national and international levels would require forceful US leadership, Mr Gore said.
''He has simply not made the case for action. He has not defended the science against the ongoing, withering and dishonest attacks.
''Nor has he provided a presidential venue for the scientific community - including our own National Academy - to bring the reality of the science before the public.''
It's hard to dispute Gore's criticisms. Obama hasn't been willing to sacrifice much political capital on this fight. That said, with America's "bought and paid for" Congress playing water carrier to the fossil fuel industries, it's hard to imagine how Obama could win.
