Niwot Ridge in the Rocky Mountains is slowly recovering from increased acidity caused by vehicle emissions in Colorado’s Front Range, suggesting that alpine regions across the Mountain West may be recovering. This is good news for the wildlife and wildflowers of Rocky Mountain National Park and for water sources that supply the Front Range and the Mountain West.

New research reveals that emissions are not growing as fast as the UN’s Intergovernmental Panel on Climate Change's assessments have indicated—and that the IPCC is not using the most up-to-date climate scenarios in its planning and policy recommendations.

A giant methane cloud caught by satellite in 2014 wasn’t a persistent hotspot, as thought at the time. Instead, the cloud was the nightly build-up of polluted air—trapped emissions of the potent greenhouse gas—near the ground.

Ever want to see inside an iguana? A new project at the CU Museum of Natural History is collecting incredibly detailed images of specimens in its collection—including CT scans of their internal anatomy.

In the spring of 2020, once-busy streets became quiet and empty. In many cities, pedestrians and bicycles filled city streets instead of cars. What could this mean for the future of our cities and transportation systems?

A very nearby supernova could wipe all life off the face of Earth. But even farther away events may still leave their mark on the planet, new research suggests.

Well-managed, healthy fisheries could serve as an important source of food for people around the world in the event of a nuclear catastrophe, a new study finds.

New research shows that as species across the world adjust where they live in response to climate change, they will come into competition with other species that could hamper their ability to keep up with the pace of this change.

A new study makes clear the extraordinary speed and scale of increases in energy use, economic productivity and global population that have pushed the Earth towards a new geological epoch known as the Anthropocene.

CU Boulder Today spoke with Louise Chawla about how children are happier and more likely to protect the natural world when they have a greater connection to it, and the important role of social and emotional support from parents, peers and community in creating hope around issues like climate change.
