Peat depositional environments, the sites where and conditions under which peat
accumulates, significantly influence a resultant coal's physical properties, chemical …

Abstract The Tibetan Plateau (TP) is one of the most sensitive areas to global climate
changes. Quantitative paleotemperature reconstructions on the TP since the Last …

Microbial lipid biomarkers preserved in geological archives can be used to explore past
climate changes. Branched glycerol dialkyl glycerol tetraethers (brGDGTs) are unique …

Despite widespread use of branched glycerol dialkyl glycerol tetraethers (brGDGTs) for
paleo-temperature reconstruction, no global calibration for their application in lakes has …

The early Eocene (56 to 48 million years ago) is inferred to have been the most recent time
that Earth's atmospheric CO 2 concentrations exceeded 1000 ppm. Global mean …

Accurate temperature records for the deep geological past are a vital component of
paleoclimate research. Distributional changes of branched glycerol dialkyl glycerol …

The distribution of branched glycerol dialkyl glycerol tetraethers (brGDGTs) in soils, peats,
and lake sediments has been shown to correlate with mean annual air temperature (MAAT) …

The response of the terrestrial biosphere to warming remains one of the most poorly
understood and quantified aspects of the climate system. One way to test the behavior of the …

East African landscapes today are the result of the cumulative effects of climate and land-
use change over millennial timescales. In this review, we compile archaeological and …

Dimethyl octacosanedioic acid (iso-diabolic acid) is a major membrane-spanning lipid of
subdivisions (SDs) 1, 3 and 4 of the Acidobacteria, a highly diverse phylum within the …
