A new synthesis published in Nature suggests that thawing Arctic permafrost will release greenhouse gases gradually, rather than in a sudden "bomb". The gradual rate of these natural emissions may give society more time to adapt to their effects, but they remain a challenge for climate mitigation.

A new Administration initiative aims to “lift America’s game” in climate education, literacy, and training. USGCRP agencies will play a central part in this effort to connect students and citizens with the best-available scientific information about climate change.

In the Caribbean, the economic importance of agriculture and tourism—combined with rural poverty and vulnerability to extreme events like hurricanes and droughts—makes adapting to climate change an urgent necessity. The International Research and Applications Project (IRAP) aims to build resilience in the Caribbean through a better understanding of how climate information can enable regional risk management.

A new pilot study by the Department of Energy (DOE) presents an approach communities can use to assess the impacts of sea level rise on energy infrastructure. Among other data sources, the study uses global sea level rise scenarios from the 2014 National Climate Assessment.

The vision for the sustained National Climate Assessment involves identifying a set of indicators that can be used to track climate changes, impacts, and responses. A roundtable at the Wilson Center will explore ways in which crowd-based approaches, such as citizen science and community-based monitoring, are and can be used to support indicator networks.

According to the UN’s World Meteorological Organization (WMO), a surge in carbon dioxide levels drove the amount of greenhouse gases in the atmosphere to a record high in 2013. Greenhouse gas levels rose more between 2012 and 2013 than at any time in the last 30 years.
