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, 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.
New research supported by the Climate Program Office's Atmospheric Chemistry, Carbon Cycle, & Climate (AC4) program was published online in the Proceedings of the National Academy of Science on Dec. 8, 2014.
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.
