C. Greenhouse Effect & Global Warming - see text pgs: Campbell 10e-1272-73* greenhouse gases act as the glass in a greenhouse does, trapping re-radiated energy like an an insulator or blanket, keeping the heat in. Increasing the concentration of these gases in the atmosphere increases the Earth's ability retain heat.

FACT:
over
the past century global temperature measurements
indicate a
0.6 ± 0.2
degree rise.
Some PREDICTIONS in a "Climate of Uncertainty"
1. IPCC -
Intergovernmental Panel on Climate
global temperature could rise by 1.4 to
5.8 degrees Celsius by 2100.
2. M.R.Appleton of Rutherford Appleton Lab in England
90% chance that the planet will warm by 1.0
to
2.5 degree C by 2040's.
