“Sharknado 5: Global Swarming” takes a campy dive into what might happen if climate change spiraled out of control — and features a raging hurricane-tornado that sucks up massive man-eaters and spits them out onto Rome, London and Amsterdam.

But as the planet heats up, wild weather patterns really do increase the chance of a fishy storm of biblical proportions, according to “Sharknado” originator Thunder Levin.

“We know that powerful enough tornadoes and hurricanes can lift large objects, including sharks if they’re passing over water,” said Levin, who wrote the screenplay for the original “Sharknado,” which aired on the Syfy channel to great finfare in 2013.
