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.

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 .

New NASA research shows that Earth's atmosphere contains an unexpectedly large amount of carbon tetrachloride (CC14), an ozone -depleting chemical that was banned worldwide decades ago. According to the study, global emissions of CCl4 average 39 kilotons per year—approximately 30 percent of peak emissions prior to its banning.

A NOAA-led study finds that over the past 30 years, the location where tropical cyclones reach maximum intensity has been shifting toward the poles in both the northern and southern hemispheres at a rate of about 35 miles, or one-half degree of latitude, per decade.
