TL;DR: In this paper, remote sensing data indicate that contemporary climate warming has already resulted in increased productivity and increased productivity in the tundra biome (Tundra Tundra Bi biome).

TL;DR: In this paper, the authors use field and remote sensing observations to document polygon succession due to ice-wedge degradation and trough development in ten Arctic localities over subdecadal timescales.

TL;DR: Biome-wide relationships between temperature, moisture and seven key plant functional traits across the tundra and over time show that community height increased with warming across all sites, whereas other traits lagged behind predicted rates of change.

TL;DR: The consistency of three approaches in estimating warming effects on plant community composition are assessed, supporting the view that inferences based on space-for-time substitution overestimate the magnitude of responses to contemporary climate warming because spatial gradients reflect long-term processes.

TL;DR: The historical sensitivity of Alaska's ecosystems to environmental change and anthropogenic disturbances is characterized using expert knowledge, remote sensing data, and spatiotemporal analyses and modeling to fill a critical gap in the understanding of historical and potential future trajectories of change in northern high-latitude regions.
