OK to Store Cards in Heat?

[All The Hype]

My mother recently brought me my card collection from when I was growing up. It doesn't have enough value to make it worth selling, but I'm far too much of a card purist to throw it away, which means it needs storing for now. I recently moved to a new house with no basement. If I put it in the garage for storage (hot summer days will surely make the garage 100 degrees or so), will the heat damage/warp the cards in any way?

Thanks for any help.

I'd be worried about any glossy cards, like Stadium Club, sticking together in 100 degree heat. Humidity is even worse.

Bedroom closet if it is dry and non humid.

Are they worthless enough to store in a burning furnace? If you don't plan to sell them, I say keep em where you want.
