At Climate-Debate.com you can read an ongoing interesting thread about UHI (Urban Heat Island) with both sides in the climate debate represented: http://www.climate-debate.com/forum/uah-reveals-urban-heat-d6-e10.php.
Frank Lansner is a very active Danish climate skeptic. Bo Vinther is a Danish climate scientist who is not afraid of arguing with the skeptics. I expect some interesting points in the discussion.
Also, you find this discussion about the possibility of a new ice age: http://www.climate-debate.com/forum/new-ice-age-d11-e11.php.
Maybe you will join the discussion?
