Climate field reconstructions from networks of tree-ring proxy data can be used to
characterize regional-scale climate changes, reveal spatial anomaly patterns associated …

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 …

A comprehensive database of paleoclimate records is needed to place recent warming into
the longer-term context of natural climate variability. We present a global compilation of …

The Arctic is warming faster than any other region on Earth. Putting this rapid warming into
perspective is challenging because instrumental records are often short or incomplete in …

The latitudinal temperature gradient between the Equator and the poles influences
atmospheric stability, the strength of the jet stream and extratropical cyclones,–. Recent …

We present a new version of the standardized Northern Hemisphere “modern” dinoflagellate
cyst (“dinocyst”) database, which includes abundances of 71 taxa at 1968 sites across the …

The large amounts of soil organic matter (SOM) in permafrost-affected soils are prone to
increased microbial decomposition in a warming climate. The environmental parameters …

Reconstructing climates of the past relies on a variety of evidence from a large number of
sites to capture the varied features of climate and the spatial heterogeneity of climate …

Predicting changes to methane cycling in Arctic lakes is of global concern in a warming
world but records constraining lake methane dynamics with past warming are rare. Here, we …

Relative to the past 2,000 years,, the Arctic region has warmed significantly over the past few
decades. However, the evolution of Arctic temperatures during the rest of the Holocene is …
