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.If levels of greenhouse gases in the atmosphere double, sea levels will rise;(3)_________________________________.Some leading experts expect a rise of 1 meter, a little more than three feet.
scientist say,the coast area should prepare for the rise of sea level
agricuture science cultivate heat resistent and dry resistent plants,to replace traditional plants
as estimated the average rise are from 1.5 feet to 6.5 feet
scientists say world coast area must prepare now for a rise in sea level.
agricultural researcher developing heat...and drive..crops but my great place to addition crops if the climate change
as atmosphere they ever drive are for 1.5feet to6.5feet
