Pat Shingleton: 'A Shell Game...'
Thousands of years ago, Incans discarded clam shells that today are a key ingredient to climatology. Weatherwise Magazine reports that shell of every clam shell provides evidence of water temperature over a two-to-three-year lifespan. The data of past water temperature is challenging a belief that El Ninos began about 8,000 years ago and were weaker compared to today. Archaeological piles of shells in Peru's Ica valley have provided evidence of water temperatures for intervals spanning 100 to 1,000 years over the past 10,000 years. These discoveries are compared to tree ring analysis. It appears that the clam shell discoveries suggest that the current understanding of the El Nino system is incomplete. El Nino experts have clammed up.
