是课文里的内容：
Turn on the evening news and you are
bound to hear about the threat of global
warming.The Earth is becoming increasingly
warmer,bringing with it a rise
in sea level and more frequent bouts of severe weather,
and strong scientific evidence points to human activity
as the cause.
Global warming,its causes,and its effects,are a complicated
story.We have already touched on some of the
issues related to climate change,and we will return to
them again later in this chapter.But first we need to understand
the interplay between surface and air temperatures
and examine how and why air temperature changes
from day to day,month to month,and year to year.
