Mapping Lightning Flash Density and Fatality Risk in Uttar Pradesh Using Satellite‐Based LIS Data and Geospatial Technology

CLEAN – Soil, Air, Water, Volume 54, Issue 2, February 2026.
This study integrates satellite‐based LIS lightning data with geospatial analysis to map lightning flash density and assess fatality risk across Uttar Pradesh (2000‒2022). Results reveal marked spatial and seasonal variability, with peak activity during the monsoon and elevated fatalities among rural male populations.

Linking palaeo‐wildfire to depositional environmental and ecological dynamics of an Early–Middle Pennsylvanian fluvial‐tidal transition zone—Palynology and pyrolysis evidence

The Depositional Record, Volume 12, Issue 1, February 2026.
The Pennsylvanian landscape in the Forest City basin was characterised by low‐lying lycopod tree and fern swamp forests with persistently high groundwater tables and adjacent fluvial channel, floodplain and upland environments. The occurrence of abundant charcoal within a specific thin interval in the Cherokee Group indicates substantial wildfire ...

New methods provide a 300‐year perspective on modern area burned in two wilderness areas of the southwest United States

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract Climate change, expanding human ignitions, and increased fuels from fire exclusion are driving increases in area burned and fire severity in dry conifer forests of the western United States. Increasing area burned is occurring against the backdrop of a large fire deficit caused by over a century of fire exclusion.
