Proceedings of National Academy of Sciences, researchers in the Climate Intervention Biology Working Group including Jessica Hellmann from the University of Minnesota Institute on the Environment explored the effect of solar climate interventions on ecology.
Composed of climate scientists and ecologists from leading research universities internationally, the team found that more research is needed to understand the ecological impacts of solar radiation modification (SRM) technologies that reflect small amounts of sunlight back into space. The team focused on a specific proposed SRM strategy referred to as stratospheric aerosol intervention (SAI)) to create a sulfate aerosol cloud in the stratosphere to reduce a portion of incoming sunlight and radiation. In theory, this cloud could be controlled in size and location.

ROCKLAND COUNTY, NY Members of the Rockland Water Coalition, along with allies and elected officials, held a virtual news conference Monday demanding New York do more to monitor, publicly disclose, and cleanup PFAS or forever chemicals in the county s water supply.
Per- and polyfluoroalkyl substances are a group of man-made chemicals, including PFOA, PFOS, GenX and many others.
PFAS contamination surfaced in the past decade as a public health concern. The federal Agency for Toxic Substances and Disease Registry cites studies linking PFAS contamination to liver problems, low birth weight, some cancers and other health issues.
Join the Embrace Winter Challenge to see Minnesota winter in a whole new light

For the next 30 days, we’ll spend 30 minutes a day outside to reduce stress, improve our immune systems and see Minnesota’s “other” season in a whole new light.

Growing up in southern India, Alarmathi Sankaran thought that 60 degrees was cold.
Then she moved to Woodbury.
“The whole concept of Minnesota winter was a great challenge to me,” Sankaran said.

Average annual temperatures in northeast Minnesota are rising, and the summer growing season is becoming sporadic and unpredictable. These trends threaten the iconic forested landscapes of the Northwoods, as well as the tourism, forestry industry and wildlife that depend on them.
“I am planning to live here and want to make sure I can walk in the woods when I’m old. We’ll need a forest for that,” said Joel Bransky, an AmeriCorps VISTA volunteer with the University of Minnesota Extension Northeast Regional Sustainable Development Partnership (Northeast RSDP).

A team led by University of Minnesota Twin Cities researchers has discovered a groundbreaking one-step process for creating materials with unique properties, called metamaterials. Their results show the realistic possibility of designing similar self-assembled structures with the potential of creating built-to-order nanostructures for wide application in electronics and optical devices.
The research was published and featured on the cover of
