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…

The Architecture for Cooling Earth Is Finally Taking Shape

The Architecture for Cooling Earth Is Finally Taking Shape First published at Inevitable & Obvious by Paul Gambill on September 30, 2025 By my estimate, fewer than a thousand people globally are working on cooling interventions. I spent four days at New York Climate Week watching a subset…

A new paradigm from the Arctic

(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…

Geoengineering Reduces Atmospheric CO2 Burden – Friedlingstein 2006

Summary - Reduced natural system sequestration with warmer temperatures causes extra carbon to remain in the sky. Any cooling, natural or human-caused, reduces natural feedback emissions which reduces the atmospheric carbon burden. Geoengineering does indeed reduce the atmospheric Greenhouse gas concentration. Abstract “Eleven coupled climate–carbon cycle models used…
