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

By aerosols, clouds, Cooling intervention governance implementation, Engineered cooling, geoengineering, Marine cloud brightening, natural geoengineering, ship's fuels regulations

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…

A new paradigm from the Arctic

By carbon cycle response, Carbon removal, direct air capture, Earth's energy imbalance, Engineered cooling, Engineered cooling scenarios, engineered cooling strategy response, geoengineering, Ice Sheets, Risk-Risk Analysis, threshold crossing, tipping
(From Moore 2025) "The prevailing “consequences-based paradigm” defines the role of climate scientists as informing the public about the negative effects of climate change, assuming this will mobilize political action to reduce emissions. Under this paradigm, research into strategies other than decarbonization is often seen as counterproductive, an...
