You should read Bjorn Lomburg more carefully he has never denied Man made climate change. I quote; "This chapter accepts the reality of man-made global warming" (p259) The Skeptical Environmentialist, 1998, By Bjorn Lomburg.
The whole issue needs much more open minded debate and the realisation that none of us really know what we are talking about. Take for example the issue of the Ice Calving in Antarctica. Much has been made about this terrifying development in Global Warming.
Well here is what the British Antartic Survey have to say about it.
"Unlike in the Arctic, where there has been a significant decline in observed sea ice extent over this period, there has been little change in the overall extent of Antarctic sea ice. However, at a regional scale, sea ice cover has declined substantially in the seas to the west of the Antarctic Peninsula but loss of ice here has been compensated by increased ice cover in other parts of the Antarctic6."
All we ever hear is the bad stuff though. They go on to state that they predict increased snow fall in the central Antarctic core and state that whilst atmospheric temperature above Antarctica has risen below 8km, above this height temperature has fallen.
The list goes on and on and that's one example.
I'm glad that someone has finally pointed out that it's no all as straight forward as Al Gore wants to brainwash us into thinking it is.
