Tae Hyun Kim What is Corn? Corn is a common large yield grain
in North America, which can be used as food and renewablr energy
resource. 332 million tons and 25% for corn ethanol-----2011 Corn
is a C4 plant, a better power to photosynthesis at a lower CO 2
concentration Affect factors: Precipitation, CO 2, Temperature
Slide 3
Tae Hyun Kim Why corn is called C4 plant?

Slide 5
Tae Hyun Kim Precipitation to Corn Precipitation is positive to
the corn field in the higher latitudes area

precipitation in inches from 1873-2008 (Data from Iowa Climatology
Bureau 2010)
Slide 7
Tae Hyun Kim Temperature to corn Higher temperature in
reasonable range is positive to the corn field in the higher
latitudes area Corn is very strict to climate environment for a
good result Growth StagePeriodAppropriate Temperature (F) Average

Tae Hyun Kim Temperature in Iowa Number of days with a maximum
temperature greater than or equal to 100 F in Iowa over the most
recent forty years (Data from Iowa Climatology Bureau 2010)

Slide 13
Tae Hyun Kim Conclusion CO2 concentration are gradually
increasing all over the world; Precipitation in Iowa will partly
increase; Temperature will partly decrease and be narrow in summer
According to compare and analyze related data, it can be predicted
that corn production keeps increasing in the condition of climate
change. Due to the increasing corn production and relative
decreasing corn prices, corn-based ethanol plant in Iowa can get
more profit from climate change, which results are different from
other negative effect of climate change.
