Data suggest that the United States may be responsible for half of global methane increase in the past decade.
Fresh insight into pyrogenic carbon disappearance suggests that erosion is not responsible.
Gas in rocky pores beneath the surface of California's Mammoth Mountain could fuel dangerous carbon dioxide emissions for the next 28 to 1100 years.
In an African region where continental crust is pulling apart and fracturing—the East African Rift zone—the area's many faults are slowly releasing a large amount of carbon dioxide.
Pledges so far by the United States, European Union, and China would require all other countries to emit 7 to 14 times less per capita than those three regions by 2030 to limit warming to 2°C.
Lower anthropogenic aerosol emissions in the 21st century may lead to warming that drives the Intertropical Convergence Zone northward.
Field experiments examine the effect of rising temperatures and drying soils on carbon dynamics in the Arctic.
A new database seeks to improve estimates of oceanic emissions of methane and nitrous oxide.
