Climate Change Global Warming

Carbon dioxide is not the only greenhouse gas. Others are as follows. 

The ability of these compounds to absorb infrared radiation varies widely from compound to compound, as does their life in the atmosphere before they undergo photochemical reactions or are absorbed in the oceans or on land. Methane has a concentration of only l.Vppmv in the troposphere, which is much less than that of carbon dioxide. On the other hand, each molecule of methane has a global warming potential (GWP) value that is 21 times that of carbon dioxide over the course of 100 years. (Note the GWP value has been developed to compare the ability of each greenhouse gas to trap infrared radiation over 100 years relative to another gas by convention, carbon dioxide has a GWP of 1.) Although methane has a relatively short lifetime (a few years) 

Likewise, it should be recognized that water vapour, which is present in the atmosphere in far greater amounts than carbon dioxide, is also a potent greenhouse gas - it accounts for at least 60-70% of the natural greenhouse effect. One has only to experience the difference in temperature on a frosty, starlit night in winter from that on a cloudy, overcast night to appreciate the 

The market for carbon permits between non-European nations may prove more difficult to establish. It has been estimated that, internationally, permits worth a trillion dollars or more per year would be required and even then, there is no guarantee that the Kyoto targets would be met. Moreover, there is no provision for how future targets are to be allocated or for enforcement of the scheme. Ultimately, it will be necessary to have a judicial body to enforce compliance, but international law is too weak at present to take on this task. Inviolate targets and time-scales are simply not practicable in the light of changing circumstances.

Global warming would also be expected to influence surface waters such as lakes and streams, through changes induced in the hydrologic cycle. However, the last published report of the IPCC states no clear evidence of widespread change in annual streamflows and peak discharges of rivers in the world (IPCC, 1995, p. 158). Wliile lake and inland sea levels have fluctuated, the IPCC also points out that local effects make it difficult to use lake levels to monitor climate variations.
