Works of Ian Rutherford Plimer
Most famous book “Heaven and Earth: Global Warming – The Missing Science” (June 2009)
503 pages, 2311 footnotes, 40 years of research cannot be ignored as useless!!
His emphasis “undergoing climate change is not unprecedented in history and the temperatures in the 20th century are not outside the range of natural variability.”
About 186 billion tonnes of CO2 enter atmosphere every year: 3.3% from human activities, 57% from oceans and 38% exhaled by humans & animals!!
Change is the only thing ‘Constant’
AndClimate is no ‘Exception’

Causes and Theories
Extra –Terrestrial (Exogenetic) Terrestrial (Endo-genetic) Anthropogenic
Extra Terrestrial :•Solar Irradiance• Sun Spots• Meteors•Milankovitch Cycles
Terrestrial :•Atmospheric•Oceanographic•Lithospheric
Anthropogenic :?????
• Atmospheric Dust Hypothesis
• Carbon Dioxide Theory
•Oceanic Levels
•Polewandering• Continental
Drifting•Paleomagnetis
m• Volcanism
Indicators of Climate Change Biological Geological Cryogenic Sea-Level fluctuation Tectonic Geomorphologic
Endo-genetic : Plate Tectonics
Negotiate the Kyoto Protocol to establish
legally binding obligations for
developed countries to reduce their
greenhouse gas emissions
