If you live anywhere El Niño has important impacts, you've heard forecasters say this year's event looks just like the monster El Niño of 1997-98. NASA satellite images of the
Pacific Ocean in November 1997 and November 2015 show almost identical, large pools of
warm water in the eastern equatorial Pacific. The National Weather Service has forecast
that impacts this winter will resemble those in 1997, when California and the South
suffered floods, mudslides and tornadoes, while residents of the Upper Midwest saved $2
billion to $7 billion in heating costs throughout their unusually warm winter.
The author emphasizes the idea that-
a. In past, El Niño has done a lot of damage.
b. The El Niño could have a large impact on many people living in the United
States this year.
C. El Niño will be a good thing for most people.
d. There is not comparison between this El Niño and any of the previous El Niños.
