I believe climate change is fundamentally the greatest threat to the integrity of our national parks that we have ever experienced. The current science confirms the planet is warming and the effects are here and now.

Climate Change
Climate change presents significant risks to our nation's natu­ral and cultural resources. Although climate change was once believed to be a future problem, there is now unequivocal scientific evidence that our planet's climate system is warm­ing (IPCC 2007a).

While many people understand that human emissions of greenhouse gases have significantly contributed to recent observed climate changes, fewer are aware of the specific impacts these changes will bring.

Research has shown that the Great Lakes region - including Pictured Rocks National Lakeshore - is experiencing climatic changes due largely to increases in human produced carbon dioxide atmospheric concentrations. These changes include increased air and water temperatures, changes in pre­cipitation patterns, and a reduction in winter ice. The changes have resultant effects on the natural ecosystems and cultural resources within and surrounding the lakes, as well as area recreational opportunities and visitor health.

Communicating Climate Change Information
Though uncertainly remains as to how climate change will manifest and how native flora and fauna will respond, it is clear that the Great Lakes region is vulnerable. An integral component of planning for climate change will be effective communication.

Our goal is to reach a wide audience extending from policy makers to local and visiting public, from scientists to students.

Bear claw scars on the smooth bark of an American beech tree.

Bear claw marks can be seen on the trunks of American beech trees because the bark is so smooth. Bears climb trees for safety and to eat beech nuts. The non-native beech bark disease is sweeping through Pictured Rocks National Lakeshore, killing many beech trees. Trees scarred with bear claw marks will be harder to find. More...
