Spurred by increasing levels of atmospheric carbon dioxide, forests over the past two decades have become dramatically more efficient in how they use water, a Harvard study has found. The research was supported by a grant from the NOAA Climate Program Office's Atmospheric Chemistry, Carbon Cycle, and Climate Program, which funded the synthesis of data from research sites across the northeastern United States.
A study by Jerome Brioude (of NOAA/ESRL/CSD and CIRES) and colleagues used data collected during NOAA's CalNex field campaign in California in 2010 to estimate emissions of CO, NOx and CO2 over the Los Angeles region.
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.
