GGR348H5 Lecture : Lecture October 17.docx
Document Summary
Average of global temperature 16 degrees, because of water vapor (should be a lot colder) The earth has been cooling for 4 billion years, and water vapor has cooled. Developed countries are pretty flat (lower economic activity and growth and more effective control over carbon dioxide) Canada has withdrawn from the kyoto target (progress has been done at municipal level) Because of central heating , driving (carbon based fuels) 10 to 20 percent precipitation, given the temperature rise it will be rain. No snow cover, land absorbs the heat (that is one of the theories of why the arctic is getting warmer) More periods of snow cover, the warmer its going to be. It is not uniform (labrador is going to be colder?) Great lakes, summer temperature is going to be warmer. Precipitation going to be 10% increase in precipitation during winter (through rain) Not much during winter, so we might have flooding problems.
