1 – Climate change will heighten ongoing risks to the Great Lakes, according to a new National Climate Assessment.

The assessment is a product of the U.S. Global Change Research Program, which was established by Presidential Initiative in 1989.
The latest report says that in the Midwest, longer growing seasons and rising carbon dioxide levels will increase yields of some crops. However, those benefits will be offset by extreme weather events. In the long term, we can expect decreased agricultural productivity.
Per capita emissions of greenhouse gases in the Midwest are more than 20 percent higher than the national average. Extreme rainfall events and flooding have increased in the last 100 years. These trends are expected to continue, causing erosion, declining water quality, and negative impacts on transportation, agriculture, human health, and infrastructure.
For the Great Lakes, the effects include changes in the range and distribution of certain fish species.
What’s to be done? The report says planning for adaptation – to address and prepare for impacts – and mitigation – to reduce future climate change – is becoming more widespread. But, “current efforts are insufficient to avoid increasingly negative social, environmental, and economic consequences.”
2 – Protecting children from environmental health hazards is the goal of new Children’s Environmental Health “wiki.”
The “wiki,” an online database, was recently launched by the Michigan Network for Children’s Environmental Health and the Ecology Center in Ann Arbor.
The Network and the Center developed the wiki as a platform for people interested in sharing research that addresses links between health problems and environmental exposures, along with related reports, policy activity and recommendations. It’s been a two-year project.
The site will be monitored by experts to assure that the information presented is based on well-referenced scientific evidence.
The wiki is organized around critical child health issues including respiratory health, asthma and cancer.
The Network and Center are inviting the research community, parents, advocates and others to join the community of people contributing to the database.
An introduction is here.
3 – Scientists at Wayne State University are researching how algae might help disrupt reproduction of zebra and quagga mussels in the Great Lakes.

Preliminary research indicates that algae produce chemicals that may inhibit spawning in the invasive mussels.
Researchers are trying to identify chemical cues released by algae, and determine how those could be used to develop a control strategy.
Such an ecological strategy would be a cleaner alternative to attacking the mussels with toxic chemicals.
Zebra and quagga mussels have caused widespread damage to the lakes since arriving in the 1980s in ballast tanks of oceangoing ships.
The mussels deprive fish of food, crowd out native mussels and clog water intake pipes.
