Climate Change and Wisconsin’s Great Lakes

Earth’s climate is changing. Human activities that increase heat–trapping (“greenhouse”) gases are the main cause. Earth’s average temperature has increased 1.4 °F since 1850 and the eight warmest years on record have occurred since 1998. Increasing temperatures have led to changes in rainfall patterns and snow and ice cover. These changes could have severe effects on the Great Lakes and the plants, wildlife, and people who depend on them. While no one can predict exactly what climate change will mean for our Great Lakes, scientists agree that the following changes are likely if climate change patterns continue.

• Increased summer and winter temperatures will cause increased evaporation, lower lake water levels and warmer water, resulting in reduced habitat for cold water species and a loss of critical wetland areas.
• Decreased winter ice cover will also contribute to increased evaporation and lower lake water levels which could have severe economic consequences for our valuable shipping industry, lakeshore recreation, and coastal businesses.
• Changes in rain and snowfall patterns (including more frequent and severe storms) could change water flow in streams and rivers and increase stream bank erosion and runoff pollution.

The good news is that we can all work to slow climate change and lessen its effects. To find out more about climate change and how we can all help, please visit the following links. Wisconsin DNR Climate Change information

The Great Lakes and a changing world

As it has done throughout the centuries, the earth is going through a change. The reasons for this change at this particular time in the earth’s long history are being debated and researched by academic entities outside the Wisconsin Department of Natural Resources. [But there’s no debate among climate scientists: human carbon emissions are rapidly changing Earth’s climate. –Des]

The effects of such a change are also being debated but whatever the causes and effects, the DNR’s responsibility is to manage our state’s natural resources through whatever event presents itself; flood, drought, tornadoes, ice/snow or severe heat. The DNR staff stands ready to adapt our management strategies in an effort to protect our lakes, waterways, plants, wildlife and people who depend on them.
