Document Summary
Long answer (choice of 2 questions, 1 based on video lecture, 1 based on class) Everything in class up to and including today. Week 5, lecture 1: biodiversity is linked to climate. Biodiversity = a term used to describe the variety of life found on earth and all of the natural processes. Atmospheric co2 concentrations were fairly stable, now increasing. We are doing something to the atmosphere that hasn"t been done before (don"t know what will happen if concentrations get higher) Depending on our decisions about greenhouse gas emissions (controlled/not), temp might increase 1 more degree or 2/3/4 degrees celsius by end of the century. Warm water expands in volume, therefore sea level will rise, levels will depend on decisions made today. Weather: shorter time periods, highly variable - short term changes in atmospheric conditions such as temperature, air pressure, humidity, precipitation, clouds/sun, wind direction. Climate: reflects average weather conditions over longer periods of time.
