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.

Although the amount of moisture stored in soil is just a small fraction of Earth’s water, it plays a big role in the Earth system. NASA’s Soil Moisture Active Passive (SMAP) satellite, launched into orbit this morning, will collect unprecedented measurements of soil moisture around the globe.

The Intergovernmental Panel on Climate Change (IPCC) released its Synthesis Report on Sunday, confirming that warming in the climate system is unequivocal and, if left unaddressed, will increase the likelihood of pervasive, irreversible damage to the environment and society. However, options to limit climate change and adapt to its impacts are available.

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.
