Through the Niwot Ridge Long Term Ecological Research Project, housed at CU Boulder's Mountain Research Station, scientists will continue to examine the impacts of a warming world on the university's highest campus.

Birds that can live at 14,000 feet and also breed at sea level might have evolved more quickly than previously thought.

Despite the Inflation Reduction Act, U.S. progress on climate change remains stuck in a climate conundrum, CU Boulder experts say, hampered by politics, complexity and the scope of the problem.

A CU Boulder-led study shows that between 1985 and 2019 in Brazil’s Atlantic Forest, deforestation decreased and reforestation increased on lands where Indigenous communities had been able to complete a legal process to receive formal recognition of their ancestral lands.

A new study based on survey data from hundreds of U.S. adults links experiencing childhood trauma to public environmental engagement later in life, such as writing letters to elected officials or donating time and resources to an organization.

Nations around the world have committed to achieve 30-by-30, protecting 30% of the planet's land and oceans by 2030. CU Boulder's Mara Goldman why this landmark is critical for the world's biodiversity, and what the challenges are to making it a reality.

A new study finds Midwestern soybean and corn farmers replaced lost airborne sulfur with sulfur fertilizer, and the environmental impacts may include downstream mercury contamination.

By analyzing Antarctic ice cores, CU Boulder scientists and an international team of collaborators have revealed the most detailed look yet at the planet’s recent climatic history, including summer and winter temperatures dating back 11,000 years to the beginning of what is known as the Holocene.

When gas leaks into and contaminates a household water well near an oil and gas drilling site, there is always a question of where it came from. Is it from a failure in the drilling or did the gas migrate naturally? New research from CU Boulder could help definitively answer that question.

The Marshall Fire spurred researchers—many of them personally affected by the fire—to pivot and apply their expertise to the aftermath. One year later, dozens of ongoing research projects continue to explore the science behind what happened that day, the widespread impacts on people, pets and the environment and how we can mitigate future catastrophes amid a changing climate.
