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…

The Architecture for Cooling Earth Is Finally Taking Shape

By climate restoration, climate triad, Cooling intervention governance implementation, geoengineering
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

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...

Explainer: How human-caused aerosols are ‘masking’ global warming (Carbon Brief)

By aerosols, clouds, global cooling pollutant, ship's fuels regulations, tropospheric aerosols

First published at Carbon Brief by Zeke Hausfather on June 10, 2025 https://www.carbonbrief.org/explainer-how-human-caused-aerosols-are-masking-global-warming/ Human-caused emissions of aerosols – tiny, light‑scattering particles produced mainly by burning fossil fuels – have long acted as an invisible brake on global warming. This is largely because they absorb or reflect incoming sunlight and…

Ocean Acidification – Another Planetary Boundary Crossed, June 9, 2025

By coral, Ocean acidification, Ocean response, threshold crossing, tipping

Coral bleaching, Great Barrier Reef Marine Park Authority, Australian Government Once a system’s degradation begins, in general it does not stop unless the thing that caused it to begin is removed. In this case, warming has caused the crossing of the ocean acidification threshold. There are situations where…
