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 .

According to the UN’s World Meteorological Organization (WMO), a surge in carbon dioxide levels drove the amount of greenhouse gases in the atmosphere to a record high in 2013. Greenhouse gas levels rose more between 2012 and 2013 than at any time in the last 30 years.

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.

On May 9, 2013, the daily mean concentration of carbon dioxide in the atmosphere surpassed 400 parts per million (ppm) for the first time since measurements began in 1958 at Mauna Loa Observatory in Hawaii.

The concentration of carbon dioxide in the atmosphere of Barrow, Alaska, reached 400 parts per million (ppm) this spring, according to NOAA measurements, the first time a monthly average measurement for the greenhouse gas attained the 400 ppm mark in a remote location.

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.

As part of its most comprehensive study of climate change to date, the National Research Council today issued three reports emphasizing why the U.S. should act now to reduce greenhouse gas emissions and develop a national strategy to adapt to the inevitable impacts of climate change.
