Cooling Climate Quickly
A New Perspective Reveals New Options
Healthy ecosystems cool the planet: rapidly and powerfully by driving water cycles, slowly but surely by sequestering carbon.

What This Paper Argues
We are losing the climate battle because our primary analytical tool — carbon accounting — blinds us to the fastest solutions available. Living ecosystems cool the planet through mechanisms largely invisible to carbon frameworks, and these mechanisms are being destroyed.
In January 2020, a shipping regulation accidentally ran a planetary experiment: cutting ship-fuel sulfur by 80% dimmed the clouds those ships had been seeding for a century. Ocean temperatures visibly warmed within months — not decades. The effect was two to four times larger than models predicted. The implication is stark: cloud formation, evapotranspiration, and biological aerosol production are fast-acting climate levers that carbon accounting simply cannot see.
Forests are the largest source of cloud-seeding aerosols over land. When forests are cleared, the same dimming mechanism fires — without anyone measuring it, funding it, or counting it. Marine phytoplankton play the same role over the ocean. Every hectare of degraded ecosystem is a missed lever.
Ecosystem degradation accounts for an estimated 15–45% of total climate forcing — comparable to fossil fuels at the upper end — and includes the only components that can be rapidly reversed. Biophysical cooling from ecosystem restoration is at least 3× carbon sequestration on the critical 10–20 year timescale, with local cooling of 2–4°C arriving within months.
These interventions produce livability — food security, water security, breathable air — as an inseparable co-product. They are not "co-benefits." They are the primary outputs of a living planet.
The paper introduces two concepts that reframe what "effective climate action" means: lability — how fast an intervention produces measurable cooling — and human-adjacency — how directly it benefits the communities who implement it. When you score interventions on lability and human-adjacency alongside magnitude, ecosystem restoration rises to the top. It is precisely the interventions invisible to carbon accounting, and therefore unfunded, that score highest.
Key Findings at a Glance
Biophysical cooling from ecosystem restoration is at least 3× carbon sequestration on the 10–20 year timescale.
Ecosystem degradation accounts for an estimated 15–45% of total climate forcing — comparable to fossil fuels at the upper end.
Every restored landscape produces a measurable island of local cooling within months of restoration.
Watts per square metre measures all climate mechanisms on equal terms — carbon and non-carbon alike.
How ERA Members Can Participate
ERA's network spans scientists, practitioners, and allied organizations worldwide. The paper is designed to be tested, amplified, and extended by that network. Three ways to engage:
Review the paper's claims, cite supporting work, challenge weak assumptions, and help locate peer-reviewed data that strengthens or qualifies the analysis. The paper welcomes rigorous critique as much as support.
