Left a dozen carbons in the back seat of my car this week...any possibility of the heat causing damage to the carbon...Had never really thought about it until I picked them up and they were pretty warm to the touch...what's your thoughts?

not to worry...in my experience you need a heat source like a flame to really hurt them

i think they will be fine seems how they are delivered by truck/ups...lol. i live in the desert and shooting at my 3d range they can get pretty warm to the touch and havent really seen any adverse or ill effects...before shooting just make sure to bend and rotate them so as to find any fractures or weak areas. otherwise should be fine  :D  good luck and happy shooting    

I'd say it should not be an issue.
