The Untold Story of How Water Governs
Our Climate
What Climate Models Miss About
the Power of Water
July 10, 17, 24 & 31
Thursdays — 12:00 noon & 7:00 pm ET
There’s a crucial piece missing from the climate conversation.
The planet has a built-in cooling system—through the cycling of water—and it’s one of nature’s most powerful, yet most overlooked, climate regulators.
We’ve already passed 1.5°C of warming. We’re beyond the safety zone. Now, we must not only prevent further heating—but also start cooling the planet using fast, affordable strategies that are proven to work!
This eye-opening course reveals how nature manages heat through water. Forests, grasslands, wetlands, and oceans are nature’s air conditioners—cycling water, forming clouds, generating rain, and releasing heat into space. When ecosystems are healthy, they keep the temperatures livable.
But human activities—like deforestation, pavement, and soil degradation—are shutting down these powerful natural systems. Here’s the good news—we can reactivate these vital cooling and hydrological cycles—starting right in our own yards and communities.
Join us for this course and discover:
- How water, not just carbon, governs the planet’s temperatures
- Why increasing plant cover can cool your community
- Simple, affordable techniques already working around the world
- The surprising role animals play in rehydrating the land
- Why forests are more than carbon sinks—they’re climate stabilizers
- Clear, practical steps to restore water cycles where you live
You already know the cooling power of water. Our bodies sweat on a hot day to cool down. All species and ecosystems work the same way—plants, trees, wildlife, people, wetlands, and oceans all help move heat and moisture through nature’s cycles—stabilizing Earth’s temperatures. Let’s harness that power—because nature can cool the planet, if we let it.
Uncover this essential part of Earth’s climate-regulating system—and learn how we can work with nature to restore a safe, livable future.

Hart Hagan is an environmental reporter who has produced nearly 400 radio shows and close to 300 videos since 2018. He is the founder of Water & Climate, a Facebook group with over 4,600 members. Six years as a climate reporter has led him to focus on the value of ecosystems and water cycles as a key driver of climate, and the primary means of curbing extinction and providing habitat for our fellow species.
Hart is passionate about educating people that in order to understand flooding, drought, heatwaves and wildfires, we must look beyond CO2 and examine how we treat our land. He is an avid gardener with a focus on native wildflowers and creating landscapes that capture all the rainfall.
Hart is also an educator, a native plant expert, an Accredited Organic Land Care Professional certified through the Northeast Organic Farming Association, and he has been trained by the Savory Institute in the ecological evaluation of pastures through a process known as Ecological Outcome Verification.
