Given the noticeably mild weather this fall and winter, it may come as no surprise that 2016 was just declared the hottest year on record. 2015 held the same title as did 2014. In other words, we have broken the record for “hottest year on record” for three consecutive years. Climate Change is a threat that affects everyone and everything in some way. We must aggressively continue global efforts to reduce the amount of greenhouse gases emitted. At the same time, communities everywhere are preparing for new weather extremes. We are one of them. Here’s a new film about our work to help prepare the Huron River for climate change. Please share this with friends to get the word out on how we are protecting the future of our local water.
HRWC would like to thank the Wildlife Conservation Society’s Climate Adaptation Fund made possible by funding from the Doris Duke Charitable Foundation for the support of this project and the creation of the film.

On a dreary Halloween morning a group of 20 intrepid University of Michigan students, boarded a trolly for a whirlwind tour of locations in Ann Arbor that show how one city is preparing for a changing climate. Guided by myself and two colleagues from the City of Ann Arbor, Jen Lawson and Jamie Kidwell, the group heard stories and learned of strategies for protecting homes from flooding, trees from dying, and residents from suffering from heat and cold related health issues and high energy costs.
As a society we still need to do everything in our power to reduce the greenhouse gas emissions that are fueling global climate change. At the same time, we are already experiencing the impacts of a changing climate which are certain to continue into the future even if greenhouse gas emissions stopped tomorrow.
In the Huron River Watershed, arguably the most potentially damaging trends we are seeing in our weather patterns are larger rainfall events and more frequent and longer high heat events. Larger storm events cause flooding and overburden or damage important infrastructure (stormwater systems, dams, water utilities, roads, homes and businesses). Consecutive high heat days are a significant threat to human health and can cause droughts and brownouts. Actions that reduce the impact of these changes can be considered climate adaptation actions, or actions that build resilience to climate change.
Ann Arbor and Washtenaw County have started making investments now that help prepare for these changes. A few examples:
- The City has conducted a detailed analysis predicting where flooding is likely to occur which is helping prioritize stormwater management decisions like where pipes need replacing and where green infrastructure (like rain gardens) can help
- Washtenaw County has recently adopted new rules requiring additional infiltration and detention of rain water for new and re-developments protecting our river from erosion, pollution and risk of damaging floods
- Ann Arbor’s Green Rental program is helping improve energy efficiency in low income areas making staying cool or warm during extremes more affordable
- The Urban Forestry and Community Forest Management Plan identifies areas that are in need of shade trees to provide cooling and recommends species likely to survive more climate extremes
The City of Ann Arbor has recently released a series of climate videos that share more about why this work is a priority and what is being done. Here is the one on extreme storms:

The students learned a lot about what is going on in their own backyard. I hope these links help you do the same. All aboard!
News to Us today highlights a couple of local stories from Milford and Scio Township. Several climate-related articles came across our desks recently including a press release on a new report connecting climate change to pest outbreaks and some promising bi-partisan legislation in New York. Finally, more fall out from the recent flooding in Detroit — raw sewage in local rivers and ultimately Lake Erie.
Milford activists aim to integrate river, downtown Recently, interested community members met in Milford to discuss the Huron River. As one of the Huron River Trail Towns, Milford is looking for ways to connect all the downtown assets available to people from the river, to parks to downtown businesses. Improved canoe landing areas, signage, and new development opportunities were among the topics discussed. Trail towns are part of HRWC’s RiverUp! program.
Scio Township imposes moratorium on oil and gas operations Following the installation of the first drilling operation in Scio Township on Miller Rd and W. Delhi, the township has established a 6-month moratorium on further oil and natural gas developments. This will give the township time to consider existing protections related to oil and gas activities such as ordinances on noise, odor, and hours of operation.
Warming Climate Brings Greater Numbers of Bugs and Outdoor Pests A new report is linking factors related to climate change are responsible, in part, for high populations of mosquitoes and ticks as well as the toxicity of poison ivy.

Legislature sends climate change bill to Cuomo Across the nation, from the federal to local levels, people are planning and taking action to prepare communities for a changing climate. Last month, New York took a significant leap by bring legislation to Governor Cuomo that would require all state-funded projects to address climate change and extreme weather into planning and implementation of these projects. Legislation passed a democratic controlled Assembly and Republican controlled Senate and awaits the Governer’s approval expected sometime late this summer.
Metro Detroit’s sewage overflow feeds Lake Erie algae growth The historic flooding that occurred in the Detroit area this August caused trouble beyond flooded roadways and basements. Many areas affected by the flood have combined stormwater and sewer systems that, when overwhelmed, deliver raw sewage directly to rivers, streams and ultimately Lake Erie further exacerbating recent water quality issues in the lake. We are fortunate in the Huron River Watershed not to have combined sewer systems. However, stormwater and sewer infrastructure failures affect us all. Improving this infrastructure to handle large rainfall events will help protect against future failures.

Resiliency is the capacity for a system to absorb disturbance without shifting into a qualitatively different state. In this case, the system we are talking about is the Huron River watershed’s trees and forests, and the disturbance is climate change. Healthy tree communities enhance stormwater infiltration, filter pollutants picked up by rainwater, keep our rivers and streams cool, and help to preserve the overall health of the Huron. Unfortunately, the River’s tree resources may be at risk due to the impacts of climate change and the extreme weather events that are expected to come with it.
With increased temperatures and extreme weather events (especially summer drought), tree species that have long been associated with the beauty of the Huron River watershed will begin shifting their population ranges north to accommodate for the change in climate. Fall foliage characterized by the vibrant reds and golds of sugar maples and beeches will be replaced by the muted browns and yellows of oaks and hickories better suited to these new weather patterns. Even the eastern white pine, the state tree of Michigan, is expected to become more rare in this area.
Many potential consequences could result from the loss of these long established tree species. High numbers of urban street trees could be lost that are not well adapted. This could mean high replacement costs for local townships. Loss of municipal services such as enhanced stormwater infiltration, air cleansing, and urban heat island mitigation may occur. With fewer native trees able to survive in the changing climate, we could also observe a loss of biodiversity and ecosystem services from our surrounding parks and forests.
So, what can we do about this? Two years ago, HRWC, the Great Lakes Integrated Sciences and Assessments Center (GLISA), and several local environmental leaders from around the watershed formed the Creating Climate Resilient Communities Project: an effort to address local climate change impacts by building resiliency in the watershed. Among the issues the project chose to focus on were resiliency strategies for natural infrastructure (specifically trees) within the watershed.
Now entering its third year, the Climate Resilient Communities Project has compiled several great resources on improving climate resiliency in the area’s forests and trees. These include a comprehensive report on the state of climate change and its impacts on the local watershed, fact sheets on key tree species of the area, and a report of popular and emerging management strategies for resilience in forest and tree resources. These and many other useful resources have been compiled as a comprehensive toolkit on HRWC’s website.
