Energy is the key to everything causes everything else. Explosive human enterprise growth abundant cheap energy (fossil fuels) Agriculture adoption 10 millenia ago 13x increase in human population. Past 150 years fossil fuel discovery = 4x expansion of population. We may soon have fewer fossil fuels to burn because the easy accessible stocks are being depleted. Coal resources available in almost every country estimated to last 164 years. Population x 1. 75, per capita wealth x 4. 15. 6% of total energy = nuclear energy. Fossil fuel emissions: fossil fuels burn waste gas (co2 more than can be absorbed by plants) atmosphere. Greenhouse effect: sun radiation thru atmosphere (cid:449)ar(cid:373)s earth"s surfa(cid:272)e re-emitted as thermal radiation (partially blocked by co2, methane, etc. , essential cushions earth from temp. extremes. Global warming: deviations in solar energy balance produces large effects leading to warming or cooling. Climate change: severe storms, increased sea level, etc. caused by deviations in solar energy balance.
