Can this be fixed? If so...how?

I first noticed it this morning and when I asked SWMBO, she said the same
thing. She doesn't recall soaking it or leaving it in a shallow puddle or
anything like that. One day it was flat, then it wasn't.

My own suspicion is that the "top" side absorbed moisture from
what was being cut on it, or from being wiped down. Or an increase in
humidity and the damp air was not able to get to the "bottom".
Regardless one side ("the top") was able to absorb more than the other
resulting in differential expansion.

While I'm not disagreeing, it just seems strange that the 3 boards in the
set all warped at the same time. As far as SWMBO and I can recall, they were
flat one day, warped the next. The one in the image is the largest. You can
see by the amount of warp that it's not something that could have sneaked
up on us. We would have noticed it way before it got that bad.

Uh-oh. "Menehunes" (The Wee Folk" of Hawaii)!

Not sure what you need to do to keep them happy.
