Over the past 3.5 million years, there have been several intervals when climate conditions
were warmer than during the pre-industrial Holocene. Although past intervals of warming …

Biomass burning and resulting fire regimes are major drivers of vegetation changes and of
ecosystem dynamics. Understanding past fire dynamics and their relationship to these …

Wildfire activity in boreal forests is anticipated to increase dramatically, with far-reaching
ecological and socioeconomic consequences. Paleorecords are indispensible for …

We examined direct and indirect impacts of millennial‐scale climate change on fire regimes
in the south‐central Brooks Range, Alaska, USA, using four lake sediment records and …

In the boreal forests of interior Alaska, feedbacks that link forest soils, fire characteristics, and
plant traits have supported stable cycles of forest succession for the past 6000 years. This …

It is widely accepted, based on data from the last few decades and on model simulations,
that anthropogenic climate change will cause increased fire activity. However, less attention …

Reconstructing specific fire-history metrics with charcoal records has been difficult, in part
because calibration data sets are rare. We calibrated charcoal accumulation in sediments …

The ongoing warming in high‐latitude regions may be causing rapid changes in the
structure and functioning of terrestrial ecosystems. Of particular concern is the fate of …

Tundra fires have important ecological impacts on vegetation, wildlife, permafrost, and
carbon cycling, but the pattern and controls of historic tundra fire regimes are poorly …

Ecosystems today are dynamic and complex, leaving conservationists faced with the
paradox of conserving moving targets. New approaches to conservation are now required …
