Stable isotope analysis points to impact of agriculture and wetlands, not fossil fuels as a driver of the rapid rise in atmospheric methane.

Ice core records of preindustrial methane indicate variability of ±30 ppb (±5%) on multidecadal-to-centennial timescales. Previous work has attribu...

Universities that run the National Center for Atmospheric Research want to keep it from being dismantled.

Blue ice records from Antarctica are used to determine methane and carbon dioxide concentrations over the past 3 million years.

We are U.S.-based scientists who have conducted research in Kalaallit Nunaat / Greenland, and we write to express our solidarity and gratitude to Greenland’s people for years of friendship and partner...

The National Center for Atmospheric Research (NCAR) has played a key role developing the science of climate modeling and the measurement of climate observations going back […]

Methane (CH4) is the second most important greenhouse gas and has been rising following a brief period of stabilization from 1999 to 2006. Determin...

Researchers are alarmed that the move might upend a long-standing tradition of peer-review for grants.

New Antarctic ice core data bolster model predictions of ocean heat content during glacials and interglacials.

Sea salt data from an ice core record show that Antarctica’s Ronne Ice Shelf survived the last interglacial, the last period of enhanced and sustained global warmth about 125,000 years ago.

An increase in wildfire extent and related greenhouse gas emissions can be linked to abrupt climatic changes during the last glacial period.
