Carbon Parts coming off due to heat!

[$w!ft]

I guess this London heat does have its disadvantages; first a piece of my roof liner came off and now I see that the carbon parts added to the interior of the car have started to warp! See pictures below.

I'm not sure if there is an easy fix to this other than buying a new set...Perhaps a heat gun and some bonding glue? Suggestions?

Mark are you able to give me a hand?
