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.

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.

Germophobes, brace yourselves. A team of CU Boulder engineers has revealed how tiny water droplets, invisible to the naked eye, are rapidly ejected into the air when a public restroom toilet is flushed. The research also provides a methodology to help reduce this exposure risk.

On the first day of the inaugural Right Here, Right Now Global Climate Summit at CU Boulder, local leaders focused on local community impacts of climate change in an adjacent track of panels.

Mitigating climate change by significantly reducing carbon emissions this decade will require big transitions in all sectors, from energy and transportation to construction and industry. But significant reductions in global emissions are possible, experts say.

Clint Carroll, associate professor in the Department of Ethnic Studies, studies Cherokee access to gathering wild plants and land use management, and tends to the land in his own backyard.

This molecular link within iodine’s atmospheric interactions can be added to global atmospheric and climate models to help scientists better understand its environmental impacts.

Assistant Professor Matt Burgess discusses the political polarization of climate change and efforts to reduce it, as voters cast their ballots in the midterm elections.

Greater attention to indoor air ventilation and filtration, rebuilding public trust and clearly communicating the dominant role of airborne transmission for SARS-CoV-2, addressing pandemic inequities and a “vaccine-plus” approach are among the recommendations made by 386 experts from more than 100 countries.

Four CU Boulder faculty will join representatives from 197 countries and hundreds of activists, scientists and industry representatives in Sharm El-Sheikh, Egypt, for the 2022 United Nations Climate Change Conference (COP27) to contribute insights on the impact of climate change on human rights, the importance of forest conservation and trends in climate change communication.
