By providing both mitigation and adaption, dam removal can lower greenhouse gas emissions and restore carbon sinks.

As the climate crisis escalates, a huge amount of attention and money is being focused on climate solutions.

These can be divided into two categories: solutions that pursue “mitigation,” which lowers greenhouse gas emissions, and those that pursue methods to adapt to climate impacts to increase human and ecological resiliency.

Dams, of course, create enormous environmental harms, many of which have already been described in scientific literature. Equally well documented is the fact that removing dams can restore seriously damaged ecosystems. But missing from almost every climate-solution story and study is how dam removal can be key for both mitigation and adaptation.

Here are 10 reasons how dam removal fights climate change.

Army Corps of Engineers studies Little River for potential dam removal

TOWNSEND — In February the Army Corps of Engineers announced a study to evaluate potential effects of proposed removal or modification of three dams on the Little River. These dams include the Townsend Dam, Peery’s Mill, and Rockford. The announcement sparked a public furor in Blount County over potential impact that dam removal might have on the Little River and adjoining communities. 

The results of the Army Corps’ study are not expected until June or July. Despite not knowing the study’s findings — which may include recommendations of full or partial removal of individual dams, or no action at all — the Blount County Commission unanimously passed a resolution in April calling for the preservation of all three dams. The resolution was sponsored by 14 of the 21 commissioners (it takes 11 votes to pass a resolution).
