When Mount Pinatubo erupted in 1991, it spewed 17 megatons of sulfate aerosols into the stratosphere, reflecting sunlight back into space and lowering global surface temperatures by 0.6°C for two years. Proponents of solar geoengineering in the global north often cite Pinatubo as a basis for highly contentious Stratospheric Aerosol Injection proposals. The Aetas of Pinatubo, however, believe the eruption was caused by Apo Namalyari, their supreme deity, angered by exploratory geothermal drilling operations on his volcanic abode.

From December 2022 to February 2023, Adaptive Radiations Working Group resided in a small riverside town in San Felipe, Zambales to investigate the lingering effects of the 1991 Mount Pinatubo eruption on the people, landscape and ecosystems on the west coast of Luzon, Philippines.

With the support of Akademie Schloss Solitude and SAVVY Contemporary Berlin through Web Residencies No.18: Magical Hackerism or The Elasticity of Resilience, Mica Cabildo and JM Quiblat collected stories, field recordings and visual documentation as raw material for a science fiction podcast.

Cloudrunner: The Pinatubo Field Guide to Solar Geoengineering is a speculative field guide for approaching climate geoengineering from diverse perspectives and integrating overlooked knowledge from those on the ground.
