Hydroclimatic changes associated with global warming over the past 50 years have been
documented widely, but physical landscape responses are poorly understood thus far …

Wildfires are an integral part of most terrestrial ecosystems. Paleofire records composed of
charcoal, soot, and other combustion products deposited in lake and marine sediments …

Mineral aerosols from dust are an important influence on climate and on marine and
terrestrial biogeochemical cycles. These aerosols are generated from wind erosion of …

Over the past several decades, high-resolution sediment–charcoal records have been
increasingly used to reconstruct local fire history. Data analysis methods usually involve a …

California fire regimes have been altered from those that occurred prior to Euro-American
settlement, and are predicted to continue to change as global climates warm. Inclusion of fire …

The potential for increased drought frequency and severity linked to anthropogenic climate
change in the semi-arid regions of the southwestern United States (US) is a serious concern …

The availability of water shapes life in the western United States, and much of the water in
the region originates in the Rocky Mountains. Few studies, however, have explicitly …

Our understanding of the present forest structure of western North America hinges on our
ability to determine antecedent forest conditions. Sedimentary records from lakes and bogs …

Ecosystems may shift abruptly when the effects of climate change and disturbance interact,
and landscapes with regularly patterned vegetation may be especially vulnerable to abrupt …

Millions of people in the arid Southwest United States rely on snow-fed Colorado River
water. Dust deposition on snow accelerates snowmelt, posing a challenge for water …
