Oh course there is climate change and global warming at work:
The Netherlands Sea Flood of 1228
England's "Death Rain" of 1316
The Grote Mandrenke Storm of 1362
The Great Storm of 1703
The Great White Hurricane of 1888
The Knickerbocker Storm of 1922
The Iran Blizzard of 1972
The list goes on and on, because Earth is still here and thriving. Even if the Climate Change doomsayers got their way and civilization regressed to the stone-age, blizzards and rainstorms will continue, because blizzards, rainstorms, floods, warming epochs, cooling epochs, polar shifts, ect., are all part of a living planet.
