Agricultural Green Revolution as a driver of increasing atmospheric CO2 seasonal amplitude

A project supported by CPO's Modeling, Analysis, Prediction, and Projections (MAPP) and  Atmospheric Chemistry, Carbon Cycle, and Climate (AC4) programs has had new research published in Nature.  The paper, "Agricultural Green Revolution as a driver of increasing atmospheric CO2 seasonal amplitude," was published in the journal's Nov. 19, 2014 issue.
New study explains wintertime ozone pollution in Utah oil and gas fields 3 October 2014

New study explains wintertime ozone pollution in Utah oil and gas fields

Chemicals released into the air by oil and gas exploration, extraction and related activities can spark reactions that lead to high levels of ozone in wintertime, high enough to exceed federal health standards, according to new NOAA-led research, published online Nature. CPO's AC-4 program supported this research.

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 2011, the United States experienced a record high number (14) of climate- and weather-related disasters where overall costs reached or exceeded $1 billion. Combined, these events claimed 670 lives, caused more than 6,000 injuries, and cost $55 billion in damages. Businesses, policy leaders, resource managers and citizens are increasingly asking for information to help them address such challenges.
