Document Summary
Compare different greenhouse gas emission scenarios for the future. Describe some of the limitations and complexities associated with gcms. Examine future temperature and precipitation projections and demonstrate their variability. First step in predicting climate is predicting future ghg emissions. Co2 directly linked to burning of fossil fuels and other ghg like ch4 and n2o, agriculture and deforestation. Different ways to determine future co2 emissions based on possible future events/circumstances. Scenarios predict future ghg emissions --> make climate projection. Co2 in the atmosphere is so important in determining future climate change. Issue is that there are soooo many steps involved and creation of scenarios takes a long time. Instead start with rcp instead of different scenarios (stories) Now develop the scenarios after figuring out future ghg concentrations. Now don"t use a1, b1 scenarios, instead use rcp #. # Climate models use outputs from the scenario models to predict future climate.
