Stable isotopes in tree rings could provide palaeoclimate reconstructions with perfect annual
resolution and statistically defined confidence limits. Recent advances make the approach …

The hyperarid core of the Atacama Desert possesses important reserves of “fossil” or ancient
groundwater, yet the extent and timing of past hydrologic change during the late Quaternary …

Tree-ring dating (dendrochronology) is a method of scientific dating based on the analysis of
tree-ring growth patterns. As author James Speer notes, trees are remarkable bioindicators …

There has been a number of investigations for the correlation between the Asia monsoon
and the North Atlantic climate for the last glacial; however, little research has been done for …

Evidence is presented for a very specific, seasonally recurring tri‐phase carbon isotope
pattern in tree rings of broad‐leaf deciduous tree species. It is derived from highly resolved …

Organic compounds of known biological origin (biomarkers) and preserved in marine
sediments have commonly been used to develop proxy records for past climate. While …

Lipid biomarkers extracted from a peat core obtained from the northeast edge of the Tibetan
Plateau have provided a 13 kyr record of regional climate change. A period of warmer …

The peat sequence at Hani in northeastern China accumulated over the past 16calkyr in a
percolation mire in which rain water and ground water seeped through the peat system. The …

In recent decades the analysis of stable isotopes in plants has become a useful method to
infer natural and anthropogenic effects on the growing conditions of plants. Here we present …

Carbon-isotope measurements (δ13C) of leaf-wax n-alkanes from the Paleocene–Eocene
Thermal Maximum (PETM) in the Bighorn Basin, Wyoming, reveal a negative carbon isotope …
