Peatland Fires Increase Between 1985 and 2023 across Alaska
FIRE IMPACTS ON WATERSHED HYDROLOGY, BIOGEOCHEMISTRY, AND BIODIVERSITY III ORAL
global environmental change | 15 december 2023
Mark J. Lara, Roger J. Michaelides, Umakant Mishra...
During recent summers anomalously warm and dry climatic conditions increased wildfires across Alaska, elevating the prevalence of peatland fires. Alth...

VULNERABILITY OF PERMAFROST CARBON TO CLIMATE CHANGE II ORAL
biogeosciences | 15 december 2023
Caroline Ludden, Christian G. Andresen, Mark J. La...
Permafrost regions are warming at a much higher rate than the rest of the world, resulting in higher rates of permafrost thaw and associated hydrogeom...

Probabilistic modeling of vegetation succession in response to thaw slump dynamics using airborne hyperspectral imaging spectroscopy
CLIMATE CHANGE IMPACTS ON GROUND ICE, THERMOKARST PROCESSES, GEOCRYOHYDROLOGY, AND ECOSYSTEM DYNAMICS OF PERMAFROST REGIONS III POSTER
cryosphere | 12 december 2023
Emma Hall, Mark J. Lara
Arctic landscapes are rapidly changing as permafrost thaws. Retrogressive thaw slumps (RTS) are a type of permafrost mass-wasting feature that alters ...
