Founded in 2021, the Healthy Planet Action Coalition (HPAC) is an international group of over 200 participants from over a dozen countries advocating urgent action to restore a safe and healthy planet.
Because of delay in action, Earth systems are beginning to collapse with foregone untenable futures baked in unless we restore our climate to restore our Earth systems.
The healthy climate triad includes actions that cool by reflection of sunlight, remove greenhouse gases from the atmosphere and reduce emissions to create a sustainable future.
Cool with known sunlight reflection strategies, Remove with 100-year old industrial processes, Reduce with strategies that are more than a generation old.

Using the most recent published data, a coalition of scientists and climate experts have created a better way forward to ensure humanity’s future . A way that is actually capable of restoring a safe and healthy climate.
Rather than the present approach of just slowing the increase in global temperatures and impacts, The Climate Triad offers an approach that in coming decades can help us restore a safe and healthy climate with the global average temperature well below 1°C above its preindustrial norm.
Restoring a safe climate would help protect the natural world and humanity – especially the most vulnerable people and least advantaged nations – while also reducing climate anxiety, protecting national and international security, democracy and reducing the number of environmental refugees, thus helping to ensure a livable planet for ourselves, our children and their children.
Climate Science at the Brink — from ClimateDiscovery.org and the Climate Change Now Initiative
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…

the oldest independent climate science education organization in the world,
the Climate Change Now Initiative 501c3
Founded in 2005, the Climate Change Now Initiative is at the forefront of climate science education. This science tells us that abrupt changes have begun 100 times more extreme and 100 years ahead of schedule. Because of the delay, too much CO2 has been emitted for emissions reductions to cool. But the delay has allowed scientists to perfect the solutions: unambigous, cheap, simple, and much different than before — but further delay is no longer optional. The newly emerging science of global warming psychology says previous education strategies have failed and new ones are needed.
Thirty years of delay
Abrupt changes have begun
Our old climate culture must rapidly change
We use the most advanced global warming psychology to enhance outreach. Thirty years of trying has resulted in advancement of impacts that will result in unrecoverable scenarios if we do not reverse warming immediately.
