Lei Wang, Ph.D.
According to Siikamaki, (2006) “Agriculture is frequently discussed in the context of climate change: not only is agriculture vulnerable to climate change, it is also part of the problem and its potential solutions.”
-Siikamaki, Juha. (2006). Climate Change and U.S. Agriculture. Examining the Connections. Environment, pg(s). 36-49.
According to Peter Backlund from NCAR,
“Human activities have altered the global climate.
During the 20th century, the global average surface
T increased 0.6 C and global sea level
increased 15 to 20 cm.”
“… human influences will continue to change Earth’s climate throughout the 21st century. The global average T will rise another 1.1 to 5.4 C by 2100. Which will result in continued increases in sea level and overall rainfall.”
- however, with continued temp increase (esp. Southern regions) some crops may not adapt.
- Northern regions may benefit most (since tend to be cooler.) e.g. longer growing season opportunity.
-- Possible to grow new crops/different crops.
