A multi-proxy investigation of late-Holocene temperature change and climate-driven fluctuations in sediment sourcing: Simpson Lagoon, Alaska

The significant and ongoing environmental changes in Arctic regions demonstrate the need for quantitative, high-resolution records of pre-industrial climate change in this climatically sensitive

Midge-inferred temperature reconstructions and vegetation change over the last ~15,000 years from Trout Lake, northern Yukon Territory, eastern Beringia

Two cores from Trout Lake, northern Yukon, yielded quantitative estimates of summer air temperatures using fossil midge larvae. Warming began around 14,400 cal yr BP, with inferred mean July air

We analyzed subfossil chironomids, sediment organic matter and sediment particle size data from a 1.11-m-long freeze core collected from Carleton Lake (unofficial name), located approximately 120 km

Nonlinear response of summer temperature to Holocene insolation forcing in Alaska

Summer temperatures during 10,000–5,500 calibrated years (cal) B.P. were generally lower than modern and that peak summer temperatures around 5,000 were followed by a decreasing trend toward the present, illustrating nonlinear responses of summer temperatures to Holocene insolation radiative forcing in the Alaskan sub-Arctic.

Proxy-based Northern Hemisphere temperature reconstruction for the mid-to-late Holocene

The observed late twentieth century warming must be assessed in relation to natural long-term variations of the climatic system. Here, we present a Northern Hemisphere (NH) temperature reconstruction

Climate variability in subarctic area for the last two millennia

To put in perspective the recent climate change, it is necessary to extend the instrumental climate records with proxy data from palaeoclimate archives. Arctic climate variability for the last two

Environmental changes of the last 1000 years on Prince of Wales Island, Nunavut, Canada

ABSTRACT A pollen record from a lake sediment core from southeastern Prince of Wales Island, Nunavut, Canada (SW08; 72.3177, −97.2678, 104 m a.s.l) provides the first high-resolution July temperature

A global database of Holocene paleotemperature records

A global compilation of quality-controlled, published, temperature-sensitive proxy records extending back 12,000 years through the Holocene, which can be used to reconstruct the spatiotemporal evolution of Holocene temperature at global to regional scales, is presented.



Pronounced climatic variations in Alaska during the last two millennia

Comparisons of this temperature record with ostracode trace-element ratios (Mg/Ca, Sr/Ca) suggest that colder periods were wetter and vice versa during the past 2000 years.

Cyclic Variation and Solar Forcing of Holocene Climate in the Alaskan Subarctic

High-resolution analyses of lake sediment from southwestern Alaska reveal cyclic variations in climate and ecosystems during the Holocene. These variations occurred with periodicities similar to

Biogenic silica concentration as a high‐resolution, quantitative temperature proxy at Hallet Lake, south‐central Alaska

High‐resolution, quantitative temperature records are valuable for placing recent warming in the context of long‐term, natural climate variability. Here we use biogenic silica (BSi) concentrations

Century‐scale solar variability and Alaskan temperature change over the past millennium

Correlation of geologic histories from 130 Alaskan glaciers with a record of solar variation suggests that multi‐decadal to century‐scale temperature variations in the North Pacific and Arctic

A chironomid-based Holocene summer air temperature reconstruction from the Swiss Alps

We developed a quantitative chironomid-July air temperature inference model based on surface sediments from 81 Swiss lakes and applied it to the Holocene subfossil chironomid record of Hinterburgsee,

Gulf of Alaska Atmosphere-Ocean Variability Over Recent Centuries Inferred from Coastal Tree-Ring Records

Eight tree-ring chronologies from coastal sites along the Gulf of Alaska (GOA) are used to develop a 227-year (1762–1988) reconstruction of spring/summer (March–September) coastal land temperatures

Midge-inferred Holocene climate history of two subalpine lakes in southern British Columbia, Canada

To investigate postglacial environmental changes in both the coastal and interior wet belts of British Columbia, fossil midges were analysed from two subalpine lakes, one adjacent to the lower Fraser
