In November last year we heard about Dr Karl Kruszelnicki's plan to debate One Nation Senator Malcolm Roberts on climate science. After some sparring on Twitter, it seemed to be locked in.

Would you like a public debate on climate science?
Dr Karl was hesitant at first, wanting to ensure that the debate would be transparent and allow "varifiable facts to predominate". He invited the Senator to have a one-on-one chat about it sometime first.
Public debate? Mmm. Most debates are about scoring points, not accuracy. Can we do it in a way that allows verifiable facts to predominate? https://t.co/VFRFypwWst— Dr Karl (@DoctorKarl) November 8, 2016
How about a private conversation, just you and me? https://t.co/VFRFypwWst— Dr Karl (@DoctorKarl) November 8, 2016
That chat took place on the weekend and it seems it did not go well. Dr Karl has decided to not go through with the proposed public debate because they "could not find common ground".
Met with Malcolm Roberts today. Unfortunately, I felt that we could not find Common Ground our proposed Debate would be pointless. Sorry. https://t.co/Eg8cGmROG3— Dr Karl (@DoctorKarl) March 26, 2017
He's published a YouTube video proclaiming his outright win over the 97 percent of scientists who affirm the existence of human-induced climate change. He claims that Dr Karl has relied on "climate academics, or climate scientists" for his position, but also says the scientist has "no evidence".
"Good news, we've won the debate on the climate science, absolutely won it because the other side has forfeited," he said in the video.
The pair have booked in another meeting in August.
