Temperature-induced water stress in high-latitude forests in response to natural and anthropogenic warming.
The Arctic is particularly sensitive to climate change, but the independent effects of increasing atmospheric CO2 concentration (pCO2 ) and temperature on high-latitude forests are poorly understood. Here, we present a new, annually resolved record of stable carbon isotope (δ(13) C) data determined from Larix cajanderi tree cores collected from far northeastern Siberia in order to investigate t...
متن کاملQuantification of High Latitude Electric Field Variability
Variability in the high latitude electric field has been identified as a major contributor to global Joule heating. Electric field patterns from the Assimilative Mapping of Ionospheric Electrodynamics (AMIE) procedure are used to characterize the E-field temporal variability over the course of 18 hours. The standard deviation of the E-field magnitude on May 4, 1998 often exceeds the average val...

متن کاملEvapotranspiration Cycles in a High Latitude Agroecosystem: Potential Warming Role
As the acreages of agricultural lands increase, changes in surface energetics and evapotranspiration (ET) rates may arise consequently affecting regional climate regimes. The objective of this study was to evaluate summertime ET dynamics and surface energy processes in a subarctic agricultural farm in Interior Alaska. The study includes micrometeorological and hydrological data. Results coverin...
متن کاملNorthern high latitude heat budget decomposition and transient 1 warming
6 Many climate models are unable to capture the magnitude of observed warming and sea ice 7 decline in high northern latitudes. To understand the factors affecting the simulated warming 8 we compare the response to increasing CO2 in two pairs of climate models by decomposing 9 the 40–90◦N region heat budget. Each pair includes a member with enhanced global and 10 northern high latitude surface ...
