A new assessment led by the Pacific Regional Integrated Sciences and Assessments (RISA) team offers insights about climate change risks in American Samoa and supports climate-wise planning
A recent study co-funded by the Regional Integrated Sciences and Assessments (RISA) program found that sea level rise caused by anthropogenic climate change increased the extent and severity of damages from the 2012 hurricane.
While other resources exist that present regional or national trends in temperatures, few tools provide such information on a local level. The dashboard incorporates overall temperature trends as well as trends in indicators like extreme heat and warm nights, offering insight into changes in heat that can have public health ramifications as well as economic impacts.
While drought is commonly defined by precipitation and runoff deficits, the study challenges this understanding by proposing a new definition: anthropogenic drought. Within human‐water systems, drought must be defined and understood as the complex and interrelated dynamics of both natural and human‐induced changes, the authors say.
“There has always been natural variability in drought events around the world, but our research shows the clear human influence on drying, specifically from anthropogenic aerosols, carbon dioxide, and other greenhouse gases,” said lead author Felicia Chiang from the University of California, Irvine.
The Climate Program Office (CPO) manages competitive research programs in which NOAA funds high-priority climate science, assessments, decision support research, outreach, education, and capacity-building activities designed to advance our understanding of Earth’s climate system, and to foster the application of this knowledge in risk management and adaptation efforts. CPO-supported research is conducted in regions across the United States, at national and international scales, and globally. Learn more...
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.
