Earth’s Changing Environment Lecture 14 Mid-Term Overview

Course Agenda Understand how energy use is currently impacting local and global environments. Estimate future impacts to Identify techniques to reduce impacts. Develop strategies for a sustainable future.

Air Quality How is fossil fuel consumption impacting air quality? CO, NOx, Sox Ozone Acid Rain

Group 2 – Technical Fixes How are technical developments helping us reduce air pollution? Catalytic Converters Scrubbers Alternative energy

Group 3 – Legislative Fixes How are national laws and international treaties helping us reduce air pollution? Clean Air Act Montreal Protocol Kyoto Protocol

Group 4 – Global Warming How is fossil fuel consumption leading to global warming? Fossil fuel combustion  CO2  global warming

Group 5 – Population Growth How is population growth impacting global warming? More energy consumption More agriculture Fewer trees - sinks

Group 6 – Global Warming Impacts What are the major anticipated impacts of global warming during the next 50 years? Sea level rise Extreme weather Species extinction

Group 7 – Global Warming Fixes What technologies could help us mitigate or adapt to global warming? Reforestation Carbon sequestration Alternative energy conservation

Group 8 – Global Warming Legislation What legislation or treaties could help us mitigate or adapt to global warming? Energy conservation legislation. International economic treaties

Let’s go to the next step!
