Experimental evidence for sustained carbon sequestration in fire-managed, peat moorlands
Prescribed burning has far less impacts on peat growth and carbon sequestration than previously thought, according to a long-term experiment in fire-managed peat moorlands in England. Managed burning may be a viable strategy to make peatlands more resilient to devastating wildfire.

Persistence of dissolved organic matter in lakes related to its molecular characteristics
Organic matter’s molecular structure has been thought to influence its decomposition. Analyses of dissolved organic carbon in Swedish lakes found that aliphatic and N-containing compounds persisted, while oxidized aromatic compounds were lost.

Fire evolution split by continent
Boreal forest fires tend to be more intense and lethal in North America than Eurasia. Differences in tree species composition explain these differences in fire regime, and lead to contrasting feedbacks to climate.

Influence of tree species on continental differences in boreal fires and climate feedbacks
Boreal forest wildfires in North America are more intense and destructive than in Eurasia. Differences in species-level adaptations to fire are primary drivers of these differences in fire regimes.

Boreal carbon loss due to poleward shift in low-carbon ecosystems
Climate change can be thought of in terms of geographical shifts in climate properties. Tracking the geographical movement of analogous climate conditions between historical and future climate model simulations, and calculating the impact of such shifts on vegetation carbon storage, suggests that boreal forests will lose carbon as low-carbon ecosystems shift in.

Recent acceleration of biomass burning and carbon losses in Alaskan forests and peatlands
Climate change has increased the area affected by forest fires in boreal North America. An analysis of the depth of burning in forests and peatlands in Alaska indicates that ground-layer combustion has accelerated regional carbon losses.

Insolation and CO2 contribution to the interglacial climate before and after the Mid-Brunhes Event
The five interglacial periods that occurred after the Mid-Brunhes Event 430,000 years ago were longer and warmer than the preceding interglacials. Climate modelling indicates that a change in the seasonality of insolation following the event, in conjunction with higher greenhouse-gas concentrations, could have caused the relative warmth.
