Report outlines solutions for curbing U.S. carbon emissions

Dec. 16, 2020

Researchers at CU Boulder’s Renewable & Sustainable Energy Institute (RASEI) on Thursday released a report outlining key steps the U.S. can take to drive CO2 emissions to zero in the key sectors of electricity, building, transportation and industry.

Impacts of COVID-19 emissions reductions remain murky in the oceans

Dec. 10, 2020

While greenhouse gas emissions dropped significantly in the first half of 2020, new research finds ocean acidification remains unchanged—yet the world's oceans can respond quickly in other ways to reduced emissions.

Niwot Ridge

Colorado mountains bouncing back from ‘acid rain’ impacts

Dec. 8, 2020

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.

United Nations Framework Convention on Climate Change COP25

Worst-case emissions projections are already off track

Nov. 30, 2020

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.

Southwest US methane hotspot is snapshot of local pollution

Nov. 24, 2020

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.

How the COVID-19 pandemic can reshape our streets and relationship to cars

Nov. 17, 2020

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?

Tree rings may hold clues to earthly impacts of distant supernovas

Nov. 11, 2020

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.
