Actually, Monckton has said on many recent videos that there has been no warming for 15 years.
Lord Monckton's own video that he produces and sells, says that right in it. He's got it on this page to sell if you want to view it. You'll see him say it there... anyone can verify it... :-)
I just saw it again last night and I can affirm that once more. But, please..., do look for yourself and see what he says...
See him on this recent video, at 2:47.
