This weeks segment talks about why Iowa and other mid-latitude states are experiencing hotter summers.
Summers in mid-latitudes, including Iowa, are warming faster than other seasons, a recent study found.
This is the Iowa Environmental Focus.
Between forty and sixty degrees latitude in the Northern Hemisphere, an area from the southern Iowa border to mid Canada warmed more rapidly in the summer than in the winter over a thirty-eight-year-period,
The study published in the journal Science attributed this finding to the fact that a substantial amount of Earth’s land mass is concentrated in this zone, and land tends to heat up more quickly than the ocean. This can have serious implications on agriculture, because much of this land is used to grow crops in the summer, particularly in Iowa.
This study was conducted using a fingerprint method, meaning the researchers could distinguish natural climatic warming from increased temperatures due to human activity.
