get a waterproof underlay, they are normally silver on one side, lay silver side face down. this should stop the moisture. ive found the floors expand nowhere near the 10 to 12mm gap your supposed to leave, even in conservatories, so problem is prob moisture.

The majority of the problems I have encountered with laminate rising is caused by moisture under the boards trying to find its way out. I would suggest lifting the affected area of the floor, AND the underlay in the same area, and letting the air get to it for a day, then relay the boards, or if possible replace the warped boards with new ones.
