Reconstructing summer intensity in the High Arctic from stem length growth of a dwarf shrub
Annual stem length growth of the circumarctic dwarf shrub Cassiope tetragona has proven to be a reliable proxy for past and ongoing climate change in the Arctic. This reliability is based on its strong linear relationship with monthly climate parameters. Monthly means are however coarse units for prediction of growth in marginal regions with short growing seasons. Growing degree-days (GDD) are ...

متن کاملReindeer grazing increases summer albedo by reducing shrub abundance in Arctic tundra
Previous studies have shown that climate warming is causing shrub cover to increase at high latitudes. Increased shrub cover generally lowers surface albedo, which results in higher energy absorption and further warming. In parts of Fennoscandia, herbivory is known to control vegetation height and abundance, and thus preventing this positive feedback. Here, we combine field measurements of albe...
متن کاملHolocene summer temperature reconstruction from sedimentary chlorophyll content, with treatment of age uncertainties, Kurupa Lake, Arctic Alaska
Quantitative records of pre-industrial temperature changes are fundamental for understanding long-term natural climate variability. We used visible reflectance spectroscopy to measure chlorophyll content (and its derivatives) in a sediment core from Kurupa Lake, north-central Brooks Range, Alaska, to reconstruct summer temperature and the number of annual non-freezing days over the past 5.7 ka....
