GWR.com / .org could be worth something if you sell it to activist groups. But that's a weird niche you could maybe get in the mid $xxx for each if you sold to the right end users. I myself would give you $10 for each of them which is saying something since a lot of the names posted in here I wouldn't even take. AddictChat.net may be worth something but I'm not good with .net.
GlobalWarmingRisk.com & org - 1,400 domains registered with 'GlobalWarming' in them, what you've got is broad enough to maybe spark some interest in $xx - low $xxx range for the set if you put up a couple of pages on them with some articles.
