Graphical abstract of the new research paper. The scientists collect samples from the rocks forming near hot springs and geysers. They dissolve small amounts of the rock in acid and organic carbon (created by living organisms) remains behind.

These photos show the kind of massive forest die-off that is projected to occur more frequently in the Southwest. Piñon pines, normally evergreen, have reddish-brown foliage in October 2002 (left). By May 2004 (right), the dead piñon pines have lost all their needles, exposing gray trunks and branches.

Sunset as seen through the smoke of a prescribed burn in the Jemez Mountains, New Mexico. The burn was conducted to restore fire as an ecosystem process and reduce hazardous tree densities and fuel loads due to more than 100 years of fire suppression. Foreground trees (Douglas-fir and aspen) were killed during the Cerro Grande fire in 2000.

USGS scientist Craig D. Allen observes the results of the extensive, tree-killing fire that consumed almost all above-ground biomass in this part of the Las Conchas Fire burn area in the Jemez Mountains, New Mexico. Photo taken in late August 2011, two months post-fire.

USGS researcher Craig Allen stands on the edge of Mesa Alta, amid diverse forest and woodland in the uplands of northern New Mexico; note some recently dead ponderosa pine and Douglas-fir in the field of view. Forest drought stress is strongly correlated with tree mortality from poor growth, bark beetle outbreaks, and high-severity fire.
