Document Summary
Earth"s energy balance and climate system (session 52) Methods and tools of climate research (session 53+54: instrumental records, short- and long-term proxies, general circulation models) Ways we can respond to climate change. Impacts that are global in extent - cumulative or synergistic effects of local/regional actions. Atmospheric and oceanic change: stratospheric ozone depletion, ocean acidification, global climatic change. Common property resources are collectively owned or communally accessed or utilized: the tragedy of the commons, global commons: outside national jurisdiction. Management of common property resources is challenging. To understand climatic change, we need to understand earth"s energy cycle. Geothermal or terrestrial energy (source: decay of naturally occurring radioactive elements, compressional heating, residual heating) Tidal energy (source: gravitational interaction between earth-moon-sun) Atmosphere+ clouds, land + soil, biosphere (mainly plants), Land + soil ( direct heating) earth loses heat by convention and conduction (which is less efficient than convection) Fossil fuels ( maturation from biosphere and pressure + heat)
