Document Summary

Lecture 11: global climate change: understand that earth shapes life and vice versa human activities have an impact on the earth we are involved in an unplanned planetary experiment. To recognize the changes we have initiated, we need to understand the earth system and how it worked before us. Earth system science seeks to understand the links and connections between the various components of the earth system: recognizes the earth as a set of interacting components forming a whole, understand the difference between climate and weather. Weather: short term changes that we observe in temperatures, clouds, precipitation, humidity and wind in a region or city. It can vary greatly from day to day. Climate: is the weather averaged over many years, locally, regionally and globally. The changes in climate are very slow ranging from 10s-1000s of years: describe the hadley cells and their role in atmospheric circulation and climate.
