It looks like global warming is doing a number on the Great Lakes.
That is according to a new report released Wednesday by the Healing Our Waters-Great Lakes Coalition.
The US Senate is expected to debate legislation next week, which could generate funding for clean-up.
But even if it passes, environmental experts say the Great Lakes will absorb some effects of climate change.
Lake levels could fall up to three feet, and there may be an increase in biological "dead zones" – areas with no fish or plant life.
