Book_Physics and Technology for Future Presidents by Richard A. Muller

I got it today for NT$1,106. It's the best price I could get on the net. It's almost half of the price I found on most of the online bookstores in Taiwan!  I love 華通書坊! Great price and great service!





Ch10. Climate Change  p363-403

The IPCC -- The Scientific ""Consensus"
The burning fossil fuels has another effect beyond global warming--one that gets attention in scientific circles but is not widely appreciated by the public.  About half of the carbon dioxide emitted from fossil fuels winds up in the oceans, and that makes the oceans more acidic.  The problem is not as immediate as acid rain, but still it can affect life in the oceans in potentially  disastrous ways. The acidification of the oceans may be a bigger danger to the ecosphere than a few degrees of additional warmth.


A Brief History of Climate
The most accurate data on the history of climate come from thermometer records covering the period from 1850 to the present. The Northern and Southern Hemispheres don't show exactly the same behavior, probably because tow-thirds of the land mass is north of the equator. 
Care must be taken not to give too much emphasis to cities. Cities are often referred to as heat islands because human materials such as asphalt on the streets absorbs more sunlight than the flora they replaced, so cities are hotter than the surrounding countryside.  Hot cities are more of a local effect than a sign of global warming.
