Although the term 'global warming' has become increasingly familiar to the general public, a recent survey carried out by the Chinchilla Institute for Environmental Studies clearly demonstrates that the full implications of the term are far from understood．As long as public consciousness remains so low, the political measures required to deal with the potentially disastrous consequences are unlikely to come about.
Over 80 percent of the people interviewed in the Chinchilla Survey were unable to point out any of the effects of a worldwide rise in temperature．Even more disturbing was the very small proportion of people interviewed (7.4%) who felt that their lives would be directly affected by global warming during the next 20 years.
This indifference is in sharp contrast to the concerns voiced by the team of professionals who conducted the Survey．Team leader Professor Ernest Wong stated that we should all expect to experience significant lifestyle．changes as a result of the effects of global warming．In detailing the possible effects, Professor Wong emphasized that the climatic changes caused by a rise in global temperature of only 1 ℃ would resuh in tremendous changes.
Primary among these changes would he the rise in sea level as a resuh of the inching of the polar icecaps(冰盖)．The consequent 30-centimetre rise in sea level would have disastrous consequences for low-lying coastal areas．The very existence of countries such as Bangladesh would be threatened．Indeed, few coastal cities would entirely escape severe flooding and damage．Although considerable debate surrounds the accuracy of Professor Wong's predictions, those who share his pessimistic pre diction insist that governments must．respond to this challenge by investing in coastal defense.
Even inland areas will not be able to avoid the consequences of global warming．Changes in the rainfall pattern are likely to result in flooding and desertification(沙漠化), both of which will influence agriculture throughout the world.
In a recent interview, Professor Wong illustrated these points with dramatic effect．Chinchilla it- self, a medium-sized provincial city at the center of' one of the country's major rice-growing areas, would, he claimed, be profoundly affected．Although, given its height and inland location, the city would not suffer from coastal flooding, the probable reduction in the rainfall would ener the economy.
In concluding his interview, Professor Wong left his audience in no doubt about the regency of the problem．'Unless we plan for the future, we will not see the necessary mobilization of forces at local, regional, national, and international level that are essential to face this issue--the issue of the 21 st century.'
The best title for this passage would be______.
