Emissions of one of the chemicals most responsible for the Antarctic ozone hole are on the rise, despite an international treaty that required an end to its production in 2010, a new NOAA study shows.
NOAA Finds Rising Emissions of Ozone-Destroying Chemical Banned by Montreal Protocol
Making Research Relevant for Decision Makers
Experts in NOAA/CIRES’ Western Water Assessment have released a new usable science guide to break down common barriers: research questions may not be targeted to resolve issues of most relevance to stakeholders, and research products such as publications or datasets are often inaccessible or impractical for use by non-experts.
In 2016’s Record Arctic Warmth, a Glimpse of the Future
A new analysis of the extraordinary heat that affected the Arctic in 2016 finds that it could not have happened without the steep increases in greenhouse gas concentrations caused by human activity, and resulting loss of sea ice, over the past 150 years. Evaluating ocean and atmospheric observations with advanced modeling tools, scientists from NOAA and CIRES found that about 60 percent of 2016’s record warmth was caused by record-low sea ice observed that year, and the ensuing transfer of ocean heat to the atmosphere across wide expanses of ice-free or barely frozen Arctic Ocean.
