We are in terra nova, a very different earth.

Humanity – genus Homo, whether it’s Homo sapiens or Homo erectus – has never existed when CO 2 levels in the atmosphere were above 300 parts per millions until around 1935. Paul Hawken: If you look at the rate greenhouse gases have increased over the last 150 years, but mainly the last 20 to 30 years, it is extraordinary. It’s like saying let’s fight the wind or ocean currents or sunshine." Photo: Paul Hawken What makes this a different approach?Īuthor and activist Paul Hawken says "You can’t fight climate change. This conversation has been edited for length and for clarity.ĭaniel Strain: Drawdown is a shift from what many who work in climate change science or policy talk about today, which is mitigation or reaching net-zero emissions. He also discusses why, in many cases, people who talk about climate change are "trying to go into a locked back door to human understanding."

Hawken sat down with Future Earth to talk about Project Drawdown. Hawken’s team reports that it could capture more than 30 billion tonnes of carbon dioxide by 2050. But there are less well-known solutions like silvopasture, a practice of raising livestock in pastures made up of trees and grasses. The list includes commonly-cited technologies like rooftop solar, which could reduce the worlds carbon dioxide emissions by 25 billion tonnes. They also included solutions that sequester carbon dioxide through land use practices by 2050. They then calculated, using computer simulations, or models, how each of those solutions could either reduce or avoid greenhouse gas emissions. To achieve this goal, Hawken and a team of scientists compiled a list of the 100 most substantive solutions to climate change. But his latest effort Project Drawdown, which has inspired a book and a website, tries for something different: It’s a how-to guide for not just slowing down climate change but reversing it – transforming the planet so that it pulls carbon dioxide back out of the atmosphere. The environmental writer and activist’s 2007 book Blessed Unrest, for example, chronicled the breadth of environmental and social justice movements around the world. Paul Hawken is no stranger to talking about climate change and other environmental crises. Getting to Drawdown: Q&A with Paul Hawken
