Proximate Climate Drivers of Beaver Pond Occupancy and Range Expansion in Arctic Alaska
To understand why beavers are colonizing the Arctic, we evaluated which climate drivers underpin beaver pond dynamics. Warm Junes, mild winters, green summers, and wet springs facilitate pond establishment. Rapid improvement in these conditions across recent decades provides mechanistic support that climate change is driving beaver colonization of the ...

Methane emissions from northern lakes under climate change: a review
Northern lakes are important sources of CH4 in the atmosphere under the background of permafrost thaw and winter warming. We synthesize studies on thermokarst lakes, including various carbon sources for CH4 emission and the influence of thermokarst ...

Little Ice Age cooling promoted peat initiation and permafrost development at the southern permafrost margin. Rapid carbon accumulation was sustained by permafrost‐suppressed decay and high photosynthetically active radiation, but recent warming‐driven drying is reducing carbon accumulation and increasing carbon‐loss risk.

Decadal-scale hotspot methane ebullition within lakes following abrupt permafrost thaw
Thermokarst lakes accelerate deep permafrost thaw and the mobilization of previously frozen soil organic carbon. This leads to microbial decomposition and large releases of carbon dioxide (CO _2 ) and methane (CH _4 ) that enhance climate warming ...

Changes in the Distribution of Thermokarst Lakes on the Qinghai-Tibet Plateau from 2015 to 2020
Thermokarst lakes are widely distributed on the Qinghai-Tibet Plateau (QTP). However, owing to the lack of high-precision remote sensing imagery and the difficulty of in situ monitoring of permafrost regions, quantifying the changes in the distribution ...

Abstract While climate‐driven increases in wildfires are altering the composition and function of Arctic ecosystems, the impact of burn severity on longer‐term changes in community composition and ecosystem fluxes remains less understood, creating uncertainty in estimates of the biome's carbon storage capacity.
