What we do

Four interconnected programs, one planetary system.

We organize our work around the environmental challenges that compound one another — and the solutions that scale across them. Each program pairs primary research with policy engagement and on-the-ground partnerships.

PROGRAM 01

Climate & Energy

Tracking emissions, modeling mitigation pathways, and mapping climate vulnerability to inform just, science-based transitions worldwide.

PROGRAM 02

Water & Oceans

From aquifer depletion to coastal flood risk and ocean health — research and tools that secure water for people and ecosystems.

The Keeling Curve at 430 ppm: reading the record that defines our era

For the first time in over two million years, atmospheric CO₂ has crossed 430 ppm at its seasonal peak. We examine what Mauna Loa's unbroken record reveals about the pace of change — and the window still open to us.

Biodiversity

Mangroves: the 10× carbon sink we keep bulldozing

Blue-carbon ecosystems store far more carbon than rainforests — yet a quarter have vanished since 1980.

Climate

El Niño in a warming world: why the cycle is breaking

The 2023–24 event shattered records. We unpack what it signals about the climate system's new baseline.

Water

The hidden crisis: groundwater and the next decade

Aquifers supply a third of humanity's water — and many are being drawn down far faster than they refill.

How we work

From data to durable change.

Measure

We gather and verify primary environmental data — from satellite observation to field measurement and open scientific records.

Analyze

Our researchers translate raw data into rigorous, peer-informed analysis, models, and scenario pathways.

Convene

We bring together policymakers, communities, scientists, and funders to align around evidence-based solutions.

Act

We support implementation on the ground — and measure outcomes openly, so progress is accountable.
