PIP: The problem of global warming (GW) is larger than it was originally suspected. The release of carbon dioxide (CO2), methane (ME), and nitrous oxide (NO2) by the activities of humans will do more than simply raise the global temperature. It will also trigger a variety of feedback loops that will accelerate the GW process. The extent of these feedback loops is currently impossible to incorporate into the computer models because they are not fully understood. But, from what we do know, it is clear that reductions in greenhouse gas (GG) emissions must be halted immediately. We are already committed to regional droughts, storms, water shortages, fishery disruptions and plant and animal extinctions. But the response of the oceans, forest, and ice masses has not yet been incorporated into our predictions. Almost all the feedbacks identified promise to increase GG concentrations. The carbon cycle is going to be affected in a variety of ways. Plants and soil store almost 3 times the CO2 as found in the atmosphere. Increased temperatures will increase plant respiration, thus increasing CO2 emissions. Forests will die, permafrost will melt and the result will be increased releases of CO2 and ME. The oceans and plankton can not absorb as much CO2 as the water temperature rises. At present levels GG concentrations will double by 2025. Thus scientists are calling for an immediate 60-80% reduction in CO2 and other GG emissions. It is up to the industrialized nations to solve this problem since they are the ones who created it. 75% of all human made CO2 comes from these countries. They also have the ability to help developing nations to do the same. 20 nations have already announced plans to stabilize or reduce their GG emissions, but it is attitudes and lifestyles that must be changed. This is the largest problem to ever face the human race and never before have we acted as we now must act in order to avoid a worldwide catastrophe.
