Global climate change: An introduction and results from the Intergovernmental Panel on Climate Change (IPCC) Fourth Assessment Report (AR4)

Abstract

This presentation gives summary of the results of the Intergovernmental Panel on Climate Change (IPCC) Working Group I (WG1) Fourth Assessment Report (AR4): The physical science basis for climate change. It begins with a history of the theory of global climate change, followed by the important concepts surrounding global climate change: the greenhouse effect and carbon cycle and how the climate has changed throughout the earth's history. It then discusses the IPCC's assessment reports, focusing on three factors: exponential growth, "feedbacks" in the system, and delays in the system.
