Molecular organic geochemical proxies are increasingly being utilized to reconstruct past
environmental conditions as new tools continue to be discovered and developed. To date …

With average temperature ranging from− 20° C at the North Pole to 30° C at the Equator and
with global warming expected to reach 1.4° C to 4.5° C by the year 2100, it is clear that …

All species have an environmental niche, and despite technological advances, humans are
unlikely to be an exception. Here, we demonstrate that for millennia, human populations …

In the absence of annual laminations, time series generated from lake sediments or other
similar stratigraphic sequences are irregularly spaced in time, which complicates formal …

Reproducible climate reconstructions of the Common Era (1 CE to present) are key to
placing industrial-era warming into the context of natural climatic variability. Here we present …

Climate in the Arctic region and northwestern Europe is strongly affected by the North
Atlantic Oscillation,(NAO), the dominant mode of atmospheric variability at mid-latitudes in …

This synthesis paper summarizes published proxy climate evidence showing the spatial and
temporal pattern of climate change through the Holocene in Arctic Canada and Greenland …

Background This paper has reviewed the international research on the terms “climate
change” and “human migration” from 1999 to 2019. To this end, a bibliometric and a cluster …

Summer temperatures on the Tibetan Plateau (TP) significantly affect stability of glaciers that
provide steady water resources to nearly half of the world population. However, lack of …
