The Great Simplification
Description
To best understand this episode, please watch this ~2 minute video on the biotic pump.
It’s widely known that Earth’s forests provide home to countless numbers of species, act as a vast sink for carbon, and provide much of the food, materials, and clean water on which our societies rely. But emerging science shows us that forests may play another critical role: making rain. This theory, called the biotic pump theory, hypothesizes that instead of being passive recipients of rain, forests may actively create the conditions for precipitation over land – a premise that turns modern meteorology on its head.
In this episode, Nate is joined by physicist Anastassia Makarieva about the critical yet often overlooked role forests play in maintaining ecological balance and climate stability. Through the lens of the biotic pump theory, she highlights the importance of moisture and rainfall cycles, the dangers of ecosystem tipping points, and the escalating risks of deforestation. Anastassia argues that a paradigm shift is needed – one that redefines how humanity understands and manages forests in the fight against global heating.
What would climate models reveal if they fully integrated the Biotic Pump Theory? How might policies protecting against deforestation evolve if societies recognized the irreplaceable role forests play in how water moves on land? And beyond policy, how might reconnecting with our deep interdependence on forests help us rediscover a richer connection to ourselves as individuals?
About Anastassia Makarieva
Dr. Anastassia Makarieva is a Russian atmospheric physicist and senior researcher at the Petersburg Nuclear Physics Institute. She obtained her Ph.D. in atmospheric physics from St. Petersburg State University in 2000. Makarieva is best known for co-developing the “biotic pump” theory alongside the late Professor Victor Gorshkov. The theory posits that forests play a crucial role in driving atmospheric moisture transport, effectively influencing rainfall patterns over land. Her work emphasizes the importance of intact forests in maintaining climate stability and has challenged conventional climate models to incorporate the dynamic role of vegetation in atmospheric processes.
In French, we have a motto that says that a simple drawing is often better than a long explanation. Jean-Marc Jancovici Carbone 4 President
That’s very understandable because with left atmosphere thinking, one of the problems is that you see everything as a series of problems that must have solutions. Iain McGilchrist Neuroscientist and Philosopher
We can’t have hundreds and hundreds of real relationships that are healthy because that requires time and effort and full attention and awareness of being in real relationship and conversation with the other human. Nate Hagens Director of ISEOF
This is the crux of the whole problem. Individual parts of nature are more valuable than the biocomplexity of nature. Thomas Crowther Founder Restor
