The U.S. Climate Modeling Summit brought together representatives from the Nation’s major research and operational climate modeling programs

A new white paper highlights outcomes from the first annual U.S. Climate Modeling Summit. The Summit brought together leadership from the country’s six premier climate modeling centers to strategize around priorities of national interest—from experimental efforts that move science forward to forecasts and projections that inform on-the-ground decisions.

Thawing permafrost releases greenhouse gases into the atmosphere

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 report investigates the causes of extreme weather and climate events that occurred around the world in 2013, finding evidence for both human and natural influences.

Requests are now being accepted for US CLIVAR sponsorship of workshops and new Working Groups for 2015. Submissions are encouraged from the U.S. climate science community with a due date of October 17.

US CLIVAR (Climate Variability and Predictability Program) has released a new Science Plan outlining its research goals and strategies for the next 15 years.

A new study concludes that the current rate of ocean acidification is higher than at any time in at least the last 300 million years and attributes this ecosystem-threatening change to the huge quantities of carbon dioxide being released into the atmosphere from fossil-fuel burning and deforestation.

The Climate Literacy presents information that is deemed important for individuals and communities to know and understand about Earth climate, impacts of climate change, and approaches to adaptation or mitigation.
