Unless this build-up is slowed, the climate of the Gulf Coast region could be noticeably altered. Global Climate Change: Global Climate Change “Weather changes all the time. The average pattern of weather, called climate, usually stays pretty much the same for centuries if it is left to itself. However, the Earth is not being left alone. People are taking actions that can change the Earth and its climate in significant ways.” Carnegie Mellon UniversityGlobal Climate Change: Global Climate Change How is the climate already changing? Why is it changing? How are humans contributing to the problem?
