Disproportionate Belowground Carbon Loss and Ecotone Sensitivity in Boreal Peatland Wildland Fires: Insights From LiDAR and Field Data

Global Biogeochemical Cycles, Volume 40, Issue 4, April 2026.
Abstract Peatlands play a critical role in the global carbon (C)‐climate cycle, acting as vast long‐term stores of disproportionately large quantities of C relative to their land area. In recent decades, climate‐driven shifts in fire regimes and peatland hydrophysical properties have occurred across Canada's boreal regions, increasing concerns about ...

The Future of Hydrogen‐Powered Aviation: Technologies, Challenges, and a Strategic Roadmap for Sustainable Decarbonization

Advanced Energy and Sustainability Research, Volume 7, Issue 3, March 2026.
Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

Incipient Fires—Definition, Detection and Extinguishment by Laypersons

Fire and Materials, Volume 50, Issue 1, Page 3-10, January/February 2026.
ABSTRACT The earlier a fire is noticed, the less developed it is and the easier it can be prevented respectively stopped, even by laypersons. Within the research project ‘TEBRAS’ the incipient phase of fires was investigated in detail. In the course of the project, it became apparent that the definition of what exactly the incipient phase of a fire ...
