Telltale for IMO Ship’s Fuel Regulations Causing Significant: Nitrogen Oxide Emissions

Telltale for the New IMO Ship’s Fuel Regulations Causing Significant Warming Since 2023: Atmospheric Nitrogen Oxide Emissions There has been a 67% reduction in ships' cloud-altering abilities after the International Maritime Organization’s ship’s fuel regulations limiting sulfur went into effect. Sulfur is a natural component of fossil fuels…

eclipse natural geoengineering

Eclipses are geoengineering experiments

The eclipse cooling phenomenon gives opportunity to study how geoengineering cooling affects our environment. When 15 percent of the sun is eclipsed, obvious cooling changes begin to happen beneath the shadow of the eclipse. This effect is what this new research is about. Cooling does more than just…
