In brief illustrate out the global energy balance.
A large raise in temperature occurred in early part of this century when emissions of Carbon dioxide and other greenhouse gases were still relatively low. But, temperatures actually cooled in 1950s and 1960s when these emissions began to raise quickly. Illustrate out the implied contradiction.
List all four (4) major gases which cause atmospheric damage and outline their sources, sinks and significance.
According to scientists, global average surface temperature has raised by less than 0.80 C in the last 100 years. Such a change is much less than what are frequently observed from one year to the next. Discuss and illustrate out the global implications.
Illustrate out why there is much concern about increase in ozone concentration near the surface of the earth and the thinning of ozone higher up in the atmosphere.
