Stratospheric variability influences emissions levels at Earth’s surface, study says

The new research in Nature Geoscience suggests that global budget estimates of ozone-depleting substances as well as other trace gases like methane could be improved by accounting for the Quasi-Biennial Oscillation’s influence.

New CPO-funded national database of CO₂ transportation emissions now available for download 20 December 2019

New CPO-funded national database of CO₂ transportation emissions now available for download

Accessible via the Oak Ridge National Laboratory Distributed Active Archive Center, the database provides the most detailed estimates available of where CO₂ is emitted from within the transportation sector and will help scientists and decision makers track how CO₂ emissions are changing over time and across U.S. cities.

New model for predicting nitrous oxide emissions from agricultural soils

Agricultural activities are the main source of nitrous oxide emissions from human activities, but there is limited attention to agriculture as a major contributor to increasing emissions likely from a lack of understanding of mechanisms controlling nitrous oxide emissions.

ABOUT OUR ORGANIZATION

Americans’ health, security and economic wellbeing are tied to climate and weather. Every day, we see communities grappling with environmental challenges due to unusual or extreme events related to climate and weather. In 2017, the United States experienced a record-tying 16 climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 362 lives, and had significant economic effects on the areas impacted, costing more than $306 billion. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
