New research tackles the uncertainty in the latest generation of global climate models' (CMIP6) projections of the first ice-free Arctic summer.
Better representation of mountain range heights could help reduce biases in how global climate models simulate important atmospheric and climate processes.
A recent study bridges observations and modeling, and shows a way to make improvements to the observational instruments climate scientists rely on to study global circulation patterns.
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.
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.
