It is predicted that over the next 70-100 years that sea temperatures will change 3 degrees C. Researchers have tried to understand how Global warming will change the fish species near Denmark. While doing so researchers have found a total of 180,000 fish bones. Most of these fish bones were Anchovey and Black Sea Breem. They noticed that the species decreased when temperatures have lowered and that the species has reappeared now that the temperature has risen a little bit. This has become a shock because this changes the life expectancy of the Cod Fish. It has been shown that their species has been decressing more. I think that this is shocking becuase it doesn't seem like old fish bones would do anything. What i also don't get is how can a species that has died over time reappear? it just seems weird.
