The National Oceanic and Atmospheric Administration (NOAA) recently released two reports that provide detailed comparisons of phases 3 and 5 of the Coupled Model Intercomparison Project (CMIP3 and CMIP5) for the United States. Understanding the strengths of these simulations and the differences among models is important for sustained assessment

Oceans, Physical Climate, Observations
A NOAA-led study refutes the much-publicized idea that there has been a recent slowdown or “hiatus” in the rate of global warming . The study finds that global warming during the last 15 years has progressed as fast or faster than during the latter half of the 20th century.

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.

The Department of the Interior, the Environmental Protection Agency, and the National Oceanic and Atmospheric Administration recently announced four collaborative landscape partnerships to make important lands and waters more resilient to climate change . Federal agencies will work with local, state, and tribal organizations in southwest Florida, Hawaiʻi, Washington, and the Great Lakes.

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 .

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 .
