Dear Dr. Briffa:
Would you be willing and available to review "A 2,326-year tree-ring record of climate variability on the northeastern Qinghai-Tibetan Plateau" by Qi-Bin Zhang, Guodong Cheng, Tandong Yao, Xingcheng Kang, submitted for possible publication in the Geophysical Research Letters.
The manuscript's abstract is:
The climate on the Qinghai-Tibetan Plateau is sensitive to global changes. High-resolution climate proxy records covering
the last two millennia in this region are scarce yet essential
to evaluation of the patterns, synchroneity and spatial extent
of past climatic changes including those in the Medieval Warm
Period (MWP) and the Little Ice Age (LIA). Here we present a
2326-year tree-ring record of spring precipitation for Dulan
area of northeastern Qinghai-Tibetan Plateau. We find that a
moist interval spanning A.D. 929-1031 occurs in the MWP, with
the peak occurring around A.D. 974. Signals associated with
the LIA are also recorded in the tree rings. The greatest
change during the last two millennia seems to occur in the
second half of the 4th century. Our tree-ring data will
facilitate intercontinental comparisons of large-scale
synoptic climate variability for the last two millennia.
