Phanerozoic Ice Ages and CO2

At least five ice ages in Earth history including Neoproterozoic (850-630 Ma) Snowball Earth

Current CO2 levelsrelatively low in the context of Earth history

Milankovitch Cycles and the Quaternary Ice Age

Current Ice Age started at 2.6 Ma

Earth has been in an interglacial for 11,000 years

Global Warming - Current Models

Causes of Current Global WarmingCO2, Solar Activity or Both?

Other Sources of Energy

Estimated world energy reserves

A world dominated by Nuclear Energy?

1 Quad = 1 quadrillion BTU

1 BTU = 252 calories

Nuclear Energy

Chain reaction

Neutron collides with U235 forming krypton and barium and releasing more neutrons + vast amounts of energy

Formation of Unconformity-type Uranium Deposits

2U6+ + + 2H2O + C = 2U4+ + 2H+ + CO2

U4+ + O2 = UO2 (Uraninite)

Tidal and hydroelectrical energy

Geothermal Energy

Geothermal Home Heating

Heat Pump
