Pollution in urban vs. oil and gas producing regions

A multi-institution collaboration of scientists, including those from NOAA/ESRL/CSD and those partly funded by CPO/AC4 program has resulted in an interesting study comparing the origins of similar levels of formic acid (a potential precursor to aerosols) in very different environments.

Efficiency of short-lived halogens at influencing climate through depletion of stratospheric ozone

As another example of NOAA’s ongoing atmospheric measurements providing an early warning system to ensure sustainable development on global scales, a new study co-authored by Stephen Montzka of ESRL and supported by the CPO/AC4 program has found that atmospheric concentrations of chlorinated hydrocarbon (dichloromethane) gas have increased by a factor of 2 since the late 1990s throughout the globe.

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.
