What is global warming? Is there really cause for alarm? Can anything be done about it? Global Warming
Greenhouse effect Our atmospheric gases trap and return a major portion of the heat radiating from the Earth. It is a natural, necessary process. 3.1 The Earth’s Energy Balance
46+23+25+6 = 100 25+6+9+60=100 9+37=46 23+37=60
3.2 CO2 Concentration vs. Earth’s temperature
The carbon cycle 3.5 60+1.5+90+6 = 157.5 0.5+61+92=153.5 157.5-153.
