News: Lake Superior Basin feeling heat: Part 2

HOUGHTON -- The next G-8 summit starts on June 6 in Germany; and, with climate change high on the agenda, George W. Bush has responded to European pressures by announcing his own counter-proposals for stemming greenhouse gas emissions. As world political leaders debate what to do about climate change, several scientists from around Lake Superior say local plants and animals are already showing the effects of rising average temperatures. Their findings range from northward shifts in bird and small mammal ranges to unexpected plankton blooms to a diminishing moose population on Isle Royale, and some are expressing concern about what a warming climate might mean for our future. more

Warmer temperatures favor ticks and make moose more vulnerable to winter tick infestations. (Photo © 2007 John Vucetich. Reprinted with permission.)
