Document Summary

Next going to look at what might happen because of climatic changes. Human role in current climatic change we are observing. Keeling curve: based on mauna loa observatory, seasonal variation in co2 in atmosphere, started by charles keeling. Warming of average temp: evapotranspiration rates, surface runoff, soil moisture, temp means and extremes. Changes in atmo circ and weather patterns: plant and animal habitats, frequency and intensity of storms, floods, droughts, growing season for crops, growing seasons may get longer. How to verify if models are good. Use past conditions to see if they become the present. Modelling a certain pathway to the future defined by ghg emissions. Temp changes will not be uniform everywhere. Some areas will have more water, some will have less. Changes are going to be different according to location. Study done for canada for the 1900s.
