Researchers have found that a whopping one-third of the fertilizer applied to grow corn in the U.S. each year simply compensates for the ongoing loss of soil fertility, costing farmers a half-billion dollars.

Roughly two billion years ago, microorganisms called cyanobacteria fundamentally transformed the globe. Researchers are now stepping back to that pivotal moment in Earth's history.

A CU ºù«ÍÞÊÓƵ geographer leads colleagues from the National Snow and Ice Data Center and CU Denver in an effort to leverage artificial intelligence for harmonizing large Earth observation datasets and mapping sea ice.

From diving Neanderthals to saliva-based COVID-19 tests, we remember the year in research at CU ºù«ÍÞÊÓƵ.

Researchers at CU ºù«ÍÞÊÓƵ’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.

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 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.
