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

Global changes in dryland vegetation dynamics (1988–2008) assessed by satellite remote sensing: comparing a new passive microwave vegetation density record with reflective greenness data
Niels Andela,Yi Y. Liu,Yi Y. Liu,A. I. J. M. van Dijk,A. I. J. M. van Dijk,R.A.M. de Jeu,Tim R. McVicar +6 more
TL;DR: In this paper, two satellite-observed vegetation products were used to study the long-term vegetation changes of global drylands: the widely used reflective-based Normalized Difference Vegetation Index (NDVI) and the recently developed passive-microwave-based Vegetation Optical Depth (VOD).

Fire and the spread of flowering plants in the Cretaceous
William J. Bond,Andrew C. Scott +1 more
TL;DR: It is suggested that forest was slow to develop until the Eocene, when fire activity dropped to very low levels, and the causes and consequences of fires in the deep past warrant greater attention.

A continent-wide assessment of the form and intensity of large mammal herbivory in Africa.
TL;DR: Four distinct herbivory regimes emerge from the analysis, characterized by forest antelopes, arid-region gazelles, high-diversity savannah fauna, and bulk feeders (such as elephants), which have had equivalent impact to those of fire and water on shaping ecosystems.

Predictability of the terrestrial carbon cycle
TL;DR: In this paper, the authors investigated fundamental properties of the terrestrial carbon cycle, examined its intrinsic predictability, and proposed a suite of future research directions to improve empirical understanding and model predictive ability.

Paleoecological Perspectives on Fire Ecology: Revisiting the Fire-Regime Concept
TL;DR: In this article, the authors use tree-ring records and lake-sediment data to examine fire occurrence across multiple spatial and temporal scales and provide relevant information for the types of fire regimes likely to occur in the future with projected climate and land use change.

TL;DR: It is shown that large wildfire activity increased suddenly and markedly in the mid-1980s, with higher large-wildfire frequency, longer wildfire durations, and longer wildfire seasons.

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.
