#ClimateAction starts in dust, rain, and quiet resolve.
Before basalt dust locks carbon deep in soils, it must journey through crushers, brave India’s monsoons, and ride hundreds of miles on the backs of trucks.
This is climate work — human, hard, and often invisible.

Since the 1950s, India has warmed by about 0.6°C, about half the rate observed in other parts of the Northern Hemisphere.
This so-called ‘cooling’ of India comes at a staggering human cost though. In 2021, aerosol pollution contributed to 2–3 million deaths in South Asia.

From Norway to Japan, @adadithya's article dives into how the giants of capital are (and aren’t) responding to the climate crisis.
Pension funds, sovereign wealth funds, & asset managers shape futures.

because when it comes to corporate emissions, the real story often starts *after* the factory gates.
• scope 1: your own smoke
• scope 2: the electricity you buy
• scope 3: the sprawling world beyond: suppliers, customers, trucks, cows, waste.

Not only is ERW the most effective and natural way to trap CO₂, it has the co-benefits of revitalizing soil health and thereby supporting livelihoods of local farmers.

Aerosols from coal, biomass, and diesel are acting as an unintended geoengineering tool — holding back heat, while taking lives.
This is the paradox we live in: we’re cooling the land with the very thing that’s poisoning our lungs.

Before basalt locks carbon in the soil, it must survive the chaos of India’s monsoons.
It must be monitored from origin to destination.
