Autism Somehow Connected to Rain
This theory is based on a comparison of autism with the weather records from three West Coast states: California, Oregon and Washington State. Researchers found that rates of autism were higher in children who lived in states where it rained a lot during their first 3 years.
How can this be? Since we suspect that autism is caused by a reaction to heavy metals in genetically susceptible infants, perhaps rain causes this type of pollution (often from power plants) to be brought closer to the ground, where it can be breathed in by infants and pregnant mothers.
