Author ProfileAbstract
The Arctic is warming four times faster than the global average,
resulting in widespread ground thaw and state changes. Due to the rapid
rate and large scale of ecosystem shifts, identifying and understanding
Arctic boreal zone changes and feedbacks requires frequent observations
across multiple scales. The last decade has witnessed significant
increases in the number and coverage of in-situ, airborne, and satellite
observations. However, additional resolution, coverage, and sustained,
long-term time series data records are urgently required to characterize
and understand the considerable heterogeneity of Northern permafrost
environments. Here, we review the physical and technical gaps that limit
the ability to detect rapid state changes and tipping points in
permafrost ecosystems. Understanding and accurately forecasting changes
to the Arctic is an essential component of managing climate change in
this rapidly transforming system.12 Jun 2024Submitted to ESS Open Archive 13 Jun 2024Published in ESS Open Archive
