Global Climate Change
Global climate change in the past, present, and future. The course focuses on evidence of climate change in the past, modern climate variability, and the range of theories and arguments regarding potential climate change in the future. The major controls on climate variability at a range of temporal scales. The modern research methods that are used to investigate past climate and to model possible climatic trends, such as global warming.
Questions the Course Will Address: Is climate changing? ; How do I measure climate change? ; What does it matter? What impact will climate change have on me? On life on earth? ; How fast is climate changing? ; What can I do about it? Can I do anything about it? ; Is human activity the cause of climate change? .
Course content: Intro: Water; Heat Budget: Atmospheric Moisture; Clouds/Dew: Historical Changes; Atmosphere Stability: Recent Glaciations; Precipiatiuon: Orbital/astronomic effects, El Nino; Air Pressure: Milankovitch cyclicity; Wind: Species Distributions; Fronts: Snowball Earth; Cyclones: Mountain-ODP, Sea Level; Forecasting: Deforestation; Thunderstorms: Hurricanes, Diseases;
Topics for discussion include the carbon cycle, solar orbital variations, monsoon variations, greenhouse warming, ozone depletion, El Niño-La Niña and ocean-atmosphere feedbacks. The human role in global change, and the response of the environment to such changes, including effects such as sea level rise, vegetation changes, and changes in ocean circulation.
