With the development of science, scientists have discovered more about the world. (1) ___________________________________. No matter what action is taken, scientists say there are already enough greenhouse gases in the atmosphere to cause a major warning. As a result, scientists and government officials are focusing on how society might adapt to rising sea levels, changing agricultural zones, changing climates and other problems. Already, state and local governments along the coast of the United States are starting to plan for a possible long-term rise in the sea level, and a few have taken action to cope with it. (2) _________________________________________. How long it will take for maximum warming to be reached is uncertain because the oceans slow such warming. Most scientists expect the maximum warming to take place by the second half of this century. (3) ______________________________________________. Some leading experts expect a rise of 1 meter, a little more than three feet

scientists say world coastal areas must prepare now for a rise of sea levels.
Agricultural researchers are developing heat-resistant and drought-resistant crops and might replace traditional crops if the climate changes.
if levels of greenhouse gases in atmosphere double sea levels for rise at the average are from 1.5 feet to 6.5 feet.作者: 差不多小姐 时间: 2012-12-17 19:36
