Climate Change and the Permafrost Carbon Feedback 9 April 2015

Climate Change and the Permafrost Carbon Feedback

New research supported by CPO's AC4 program has been published in Nature. "Climate Change and the Permafrost Carbon Feedback" focuses on the large quantities of organic carbon are stored in frozen soils within arctic and sub-arctic regions.
The Chemistry of Atmospheric Brown Carbon 3 April 2015

The Chemistry of Atmospheric Brown Carbon

A team of scientists partially funded by CPO's Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program published a Chemical Reviews article on the chemistry of atmospheric "brown carbon,"-- the atmospheric aerosol contributing to the brown color of smoggy air.

Pollution in urban vs. oil and gas producing regions 2 April 2015

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 3 March 2015

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.

CarbonTracker CT2013B Update 17 February 2015

CarbonTracker CT2013B Update

CarbonTracker, a CO2 measurement and modeling system developed by NOAA to keep track of sources (emissions to the atmosphere) and sinks (removal from the atmosphere) of carbon dioxide around the world, has come out with its latest update: CT2013B. This effort is supported by CPO's AC4 Program.

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.
