In the wake of December’s Paris climate agreement, environmental scientist and Greenpeace co-founder and President Dr Patrick Moore offered a stonker of a bet:

To confirm, I raise my bet to US$100,000 that global CO2 emissions will be higher ten years from now than in 2014, based on IEA & GCP.

With a $100 billion climate fund backing 188 nations’ commitments to cut greenhouse gas levels – including a minimum 40% cut from the EU – this bet seems like a sure investment for eco-warriors with cash to burn.

But more than a month later, nobody has taken up Dr Moore’s offer. Do the climate lobby not have faith in the “world’s greatest diplomatic success” to have a flutter?
