Episode: Professor Johan Rockström on Climate Change
Host: LSE Film and Audio Team (Professor Stefan Chambers)
Guest: Professor Johan Rockström
Date: March 7, 2022

Overview

This episode features a deep-dive conversation between Professor Johan Rockström, a leading climate scientist and co-director of the Potsdam Institute for Climate Impact Research, and Professor Stefan Chambers, Director of the LSE Marshall Institute. The discussion centers on humanity's critical moment in the Anthropocene: whether we are risking the destabilization of the Earth’s systems, our proximity to “irreversible on buttons” for planetary tipping points, and the role of science, policy, philanthropy, and intergenerational justice in addressing the climate crisis.

Key Discussion Points & Insights

1. The Anthropocene: Humanity at a Crossroads

• Context: We are living in the Anthropocene, an epoch defined by humanity’s dominant impact on Earth’s geology and ecosystems.
  • Quote:
    “For the first time, myself and scientific colleagues around the world are forced to explore the following. Are we at risk… of destabilizing the entire planet?”
    — Professor Rockström [00:04]
• This era represents a moment as significant as the Darwinian or Copernican revolutions.
  • Quote:
    “We are at a historical moment that is as potentially as significant as the Darwinian moment or the Copernican moment.”
    — Professor Chambers [02:08]

2. Tipping Points and the “On Button” Analogy

• The risks of crossing planetary boundaries are not tied to a single “on button” but rather a series of thresholds.
  • Quote:
    "It's not one button, it's many buttons. And they can add up to one big button potentially... When we pass 1.5 degrees Celsius warming, we are at risk of pressing the first set of buttons."
    — Professor Rockström [03:06]
• These include irreversible loss of Arctic summer sea ice, dramatic changes in the Antarctic, and tipping over ecosystems like rainforests.
• Irreversibility:
  "Once we've pressed them, we cannot turn back. Then we cross thresholds, we cross tipping points and the Earth system takes over from being a self cooling friend to becoming a self worth warming foe."
  — Professor Rockström [03:46]
• Science-based planetary boundaries are essential to avoid “pushing these systems too far.”

3. State of Knowledge: From Science to Implementation

• Scientific consensus is robust: We know what needs to be done, but the problem now lies in political will, economic systems, and societal values.
  • Opinion polls show 60-70% of people globally support climate action.
  • "The challenge is really how do we unleash the pathways towards solutions... It's in the political realm. It's in the business and economic markets, and it's also in the behavior of fellow citizens.”
    — Professor Rockström [05:13]
• Scientific warnings have become more urgent as evidence accumulates—1.5°C warming is now seen as a "hard biophysical boundary."

4. Philanthropy: Where and How to Push

• Many listeners are philanthropists unsure where their efforts would be most impactful.
• Rockström's advice:
  1. Shift the Narrative: Invest in demonstrating that sustainability (climate, nature, pollutants) leads to better societal outcomes: jobs, health, security, growth.
     • E.g., “Seven million people per year die prematurely of air pollution… Go to electric mobility and public transport… you get basically healthier people, more resilience… better handling of future pandemics." [08:09]
  2. Immediate Actions:
     • Stop investment in coal; push for phase-out of fossil combustion engines and oil/gas extraction.
     • Build strong alliances in finance and industry to shift investment flows.
     • Transform the global food system from the largest greenhouse emitter to a carbon absorber.
  3. Financial Tipping Points:
     "Once that flow [of finance] changes direction… that can in the end create its own social tipping point... making that flow unstoppable."
     — Professor Rockström [11:20]

5. COP26: What Constitutes Success?

• Five Key Indicators to Watch:
  1. Each country’s updated, science-aligned national climate plan (“Nationally Determined Contributions”).
  2. “Money on the table”—filling the global climate fund, with new investments, especially for nature-based solutions.
  3. First “Nature Climate COP”—integration of forestry, soils, and agriculture into climate agenda.
  4. Commitments to phase-out coal and combustion engines from major economies.
  5. Introduction of a global price on carbon.
• “Every country in the world must exit Glasgow presenting a plan that makes us align with science on the emission pathway so that we can hold the 1.5 degrees Celsius lines.”
  — Professor Rockström [12:51]

6. Why so Little Philanthropy for Climate?

• Only ~2% of global philanthropic capital goes to climate.
• The false divide: climate and biodiversity seen as a niche “environmental” issue, separate from mainstream funding for health, human rights, and democracy.
  • “We don't have environmental problems in the world anymore. We have only security, stability, health, democracy, human rights challenges. And the sustainability dimensions is an integral part of this.”
    — Professor Rockström [15:49]
• Rockström urges a “whole new logic” that sees sustainability as central to human well-being and societal resilience.

7. Intergenerational Justice and Moral Responsibility

• Our economic and political systems lack mechanisms for responsibility beyond short time horizons.
• “We have to prolong our moral timeline of responsibility... it should be centuries to thousands of years.”
  — Professor Rockström [18:32]
• The climate crisis is a “dramatic moral obligation,” and current generations risk being the first to fail in their custodial responsibilities.
• Fridays for Future and youth movements are right to demand accountability.

Notable Quotes & Memorable Moments

• “Are we at risk... of destabilizing the entire planet?”
  — Professor Rockström [00:04]
• “It's not one button, it's many buttons...”
  — Professor Rockström [03:06]
• “Opinion poll after opinion poll shows that roughly 60, 70% of citizens across the world are really concerned about climate change and want climate action.”
  — Professor Rockström [05:13]
• “Seven million people per year die prematurely of air pollution... you get rid of fossil fuel burning, you go to electric mobility and public transport in cities, you can clean up New Delhi, you get better lung capacity, you get basically healthier people, more resilience, more robust, better handling of future pandemics.”
  — Professor Rockström [08:21]
• “Once that flow changes direction… that can… create its own social tipping point.”
  — Professor Rockström [11:20]
• “We don't have environmental problems in the world anymore. We have only security, stability, health, democracy, human rights challenges. And the sustainability dimensions is an integral part of this.”
  — Professor Rockström [15:49]
• “We have to prolong our moral timeline of responsibility… it should be centuries to thousands of years.”
  — Professor Rockström [18:32]
• “We are the first generation ever to likely fail that moral responsibility, because we are the ones right at this time step that are coming close to those on buttons. We have the window still open to avoid it, but the window is shutting very fast.”
  — Professor Rockström [19:15]
