DULUTH, Minn. (AP) ó Normally frigid Lake Superior has warmed up faster than
usual this summer. Researchers at the University of Minnesota Duluth say
thatís due to a winter with little ice and a record-warm spring.
They say surface water temperatures are already about 20 degrees higher than
normal at one buoy in western Lake Superior. And they say water temperatures
could reach a record high by mid-August.
Thatís good news for people who want to swim in Superiorís typically
bone-chilling waters, but the long-term implications arenít clear. It could
mean a more fertile lake with more organisms that thrive in warmer
conditions. But lake trout may have to move deeper or further offshore.
The warmer water also means warmer breezes on shore.
