Hi, there! Im Amy Clement. Im an oceanographer at Columbia University in New York City. I study how the ocean affects the climate around the world. Climate is the typical weather pattern for a certain area of the world. Near the Equator, for example, the climate is very hot all year. Near the North Pole, the climate is always bitter cold.
As you probably know, the change of seasons - winter, spring, summer, and fall - affects climate. Another thing that can change the climate is El Niņo (el-NEEN-yo). El Niño is difficult to study because so many different factors influence climate.
