Climate Reversal The climate and environment of the Arctic have changed drastically over the short course of modern observation. Kaufman et al. (p. 1236) synthesized 2000 years of proxy data from lakes above 60° N latitude with complementary ice core and tree ring records, to create a paleoclimate reconstruction for the Arctic with a 10-year resolution. A gradual cooling trend at the start of the record had reversed by the beginning of the 20th century, when temperatures began to increase… 

Unprecedented recent summer warmth in Arctic Canada

Arctic air temperatures have increased in recent decades, along with documented reductions in sea ice, glacier size, and snow cover. However, the extent to which recent Arctic warming has been

Arctic Climate Change, Variability, and Extremes

Global warming over the past half century has been amplified in the Arctic, especially in the cold season. Other Arctic indicators, especially those of the cryosphere, show signals consistent with

Ongoing Climate Change in the Arctic

During the past decade, the Arctic has experienced its highest temperatures of the instrumental record, even exceeding the warmth of the 1930s and 1940s. Recent paleo-reconstructions also show that

Current Siberian heating is unprecedented during the past seven millennia

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 polar regions and

Warm Arctic−cold Siberia: comparing the recent and the early 20th-century Arctic warmings

The Warm Arctic–cold Siberia surface temperature pattern during recent boreal winter is suggested to be triggered by the ongoing decrease of Arctic autumn sea ice concentration and has been observed

Reconstructed changes in Arctic sea ice over the past 1,450 years

TLDR
A network of high-resolution terrestrial proxies from the circum-Arctic region is used to reconstruct past extents of summer sea ice, and shows that both the duration and magnitude of the current decline in sea ice seem to be unprecedented for the past 1,450 years.

Northeast Siberian ice wedges confirm Arctic winter warming over the past two millennia

Arctic climate has experienced major changes over the past millennia that are not fully understood in terms of their controls and seasonality. Stable isotope data from ice wedges in permafrost

Global warming triggers the loss of a key Arctic refugium

TLDR
The rapid transformation of one of the Earth's last remaining Arctic refugia is document, a change that is being driven by global warming, exceeding the range of regional long-term variability.

Highly variable Northern Hemisphere temperatures reconstructed from low- and high-resolution proxy data

TLDR
This reconstruction of Northern Hemisphere temperatures for the past 2,000 years is reconstructed by combining low-resolution proxies with tree-ring data, using a wavelet transform technique to achieve timescale-dependent processing of the data.

Proxy-based reconstructions of hemispheric and global surface temperature variations over the past two millennia

TLDR
The results extend previous conclusions that recent Northern Hemisphere surface temperature increases are likely anomalous in a long-term context to at least the past 1,700 years, but with additional strong caveats.

TLDR
A coupled climate system model was used to determine whether proxy-based irradiance series are capable of inducing climatic variations that resemble variations found in climate reconstructions, and if part of the previously estimated large range of past solar irradiance changes could be excluded.
