Global sea levels have risen, which led to greater damage in coastal areas than what would have occurred with the same storm 20 years earlier. Global temperatures have risen, which leads to more powerful storms. Hurricane Sandy just happened to be the largest hurricane ever in the Atlantic Ocean. The amount of damage done by Sandy shows climate change in action.
It's hard to determine what I would pursue if I majored in Geology because there are many different directions I would find interesting. Using my expertise to help clean up areas, like abandoned mines, would be very rewarding. Studying volcanoes and trying to improve detection methods would be interesting. Analyzing the geological features of other planets and asteroids would probably be the coolest career
