HUMAN INDUCED EXTINCTION REJECTED

In 2005 researchers at The Australian National University claimed Australia's megafauna was killed off by human induced climate change:

Disruption to the ecology of the Australian landscape caused by the burning practices of the continent’s first inhabitants probably led to the extinction of megafauna 50,000 years ago, according to new research.

Researchers at the Queensland University of Technology have opted for a more politically correct explanation:

"So it's most likely that Australia's giant kangaroos and other megafauna in this area were driven to extinction by the hands of Mother Nature."

Where's the scientific consensus we've been hearing so much about?
