As long as it was sealed shut - sorb is extremely temperature resistant really, the only issue would be drying out (hence sealed - not about CO2 getting inside in a couple of days, but the moisture going out).
I had some sorb in a really hot metal shed, forgot about it, but it was new, sealed, used it since then in heavy diving and never any issue.
From what I remember sorb at 600C+ actually starts to regenerate, but I don't think you're aiming for those kinds of temperature in your crawlspace.

Data sheet should always be the first stop. It gives 0-35C for the safe storage range. 100F is 38C, up to you if you think 3degC will make a difference. I would imagine a shipping container in summer tops out well above that, I can't imagine they're moving lime refrigerated.
I wonder who writes those SDSs. Sodalime can reach 100C in operation and keeps its performance (or even improves it). AFAIK the only risk of heating (in sane range) is drying out.

They are written for the lowest common denominator of human being and know that 0-35 is a reasonable operating range for most people.
It's probably the limits of whatever the test range or standard was specified (assuming it comes from testing and not just a desktop study). If you don't ask a lab to test to failure then they won't test to failure. Well they probably will, they just won't certify for anything you haven't paid for. If you've paid to know it's OK between 0 & 35C then that's all you're getting paperwork for.
This is what I meant:
Investigation and Possibilities of Reuse of Carbon Dioxide Absorbent Used in Anesthesiology - PMC
Absorbents used in closed and semi-closed circuit environments play a key role in preventing carbon dioxide poisoning. Here we present an analysis of one of the most common carbon dioxide absorbents—soda lime. In the first step, we analyzed the ...

Researchers heated sodalime to NINE HUNDRED CENTIGRADE (something else in freedom units) to regenerate it (with success).
In other words - it was tested to be fine up to at least 900C (if you can reintroduce appropriate levels of humidity again).
So once again - heat away, just take care not to dry it out (now that is a BIG problem).
