Orange Milankovitch cycles are strongly correlated with cyclical changes in the earth’s temperature and the corresponding advances and retreats of glaciers (glacial & interglacial periods). See Fig 13.6 2 Carbon-problem Characteristics Annual rate of C or CO 2 from fossil fuel burning (giga tonnes / yr) CO 2 accumulation in the atmosphere (giga tonnes or ppm, concentration) CO 2 molecular weight = 12 + (2 X 16) = 44 Carbon isotopes: C 12 (99%) plants prefer this isotope C 13 (1%) plants don’t prefer it C 14 (1ppt) radioactive (half life = 5730yr); carbon dating Combustion...
