TLDR
What is known and what is needed to develop a holistic understanding of the role of fire in the Earth system are reviewed, particularly in view of the pervasive impact of fires and the likelihood that they will become increasingly difficult to control as climate changes.Abstract:
Fire is a worldwide phenomenon that appears in the geological record soon after the appearance of terrestrial plants. Fire influences global ecosystem patterns and processes, including vegetation distribution and structure, the carbon cycle, and climate. Although humans and fire have always coexisted, our capacity to manage fire remains imperfect and may become more difficult in the future as climate change alters fire regimes. This risk is difficult to assess, however, because fires are still poorly represented in global models. Here, we discuss some of the most important issues involved in developing a better understanding of the role of fire in the Earth system.read more

Black carbon aerosol dynamics and isotopic composition in Alaska linked with boreal fire emissions and depth of burn in organic soils
G. Mouteva,Claudia I. Czimczik,Simon Fahrni,E. B. Wiggins,Brendan M. Rogers,Sander Veraverbeke,Xiaomei Xu,Guaciara M. Santos,J. Henderson,Charles E. Miller,James T. Randerson +10 more
TL;DR: Mouteva et al. as discussed by the authors measured the isotopic composition of BC and organic carbon (OC) aerosols collected at two locations in interior Alaska during the summer of 2013, as part of NASA's Carbon in Arctic Reservoirs Vulnerability Experiment.

The Burning Issue
TL;DR: High-precision measurements, taken from air trapped in Antarctic ice, of how atmospheric concentrations of CO have changed over the past 650 years offer a striking and surprising look at the history of fire in the Southern Hemisphere, and some hints at future global fire trends.
Journal ArticleDOI
Corridors promote fire via connectivity and edge effects
TL;DR: This work collects data during prescribed fires in the world's largest and best replicated corridor experiment, to test several mechanisms for how corridors might influence fire and presents the first experimental evidence that corridors can modify landscape-scale patterns of fire intensity.

TL;DR: This work uses the recently published GlobBiomass data set of forest above-ground biomass (AGB) density for the year 2010 to evaluate AGB estimated by nine dynamic global vegetation models (DGVMs) and analyzes empirical relationships between AGB density deficits and forest cover changes, population density, burned areas and livestock density.

Forests and Climate Change: Forcings, Feedbacks, and the Climate Benefits of Forests
TL;DR: Interdisciplinary science that integrates knowledge of the many interacting climate services of forests with the impacts of global change is necessary to identify and understand as yet unexplored feedbacks in the Earth system and the potential of forests to mitigate climate change.
