In 2012, the atmospheric effects from human activities influenced at least six extreme weather and climate events.
The study "Explaining Extreme Events of 2012 from a Climate Perspective," released by the American Meteorological Society (AMS), analyzed 12 different events from 2012. Here are the six events they tied to human-induced climate change as well as two where they could not find a definitive link.
The first to top the list with a "hit" was Superstorm Sandy. The annual probability of a Sandy-like storm deluging New York, New Jersey and other parts of the East Coast has nearly doubled compared to 1950. Even weaker storms will be more damaging now than they were ten years ago because of rising sea levels.
The global sea level rises along with the temperature for two major reasons. For one, heat causes water to expand, which causes the existing water to take up more space and encroach on the coast. At the same time, ice at the poles and in glaciers melts and increases the amount of water in the oceans.
