The article explores the risk that self-reinforcing feedbacks could push the Earth System towards a planetary threshold, leading to a "Hothouse Earth" pathway with severe consequences for ecosystems, societies, and economies. The authors examine the evidence for such a threshold and suggest that it could be as low as a 2°C increase in global temperature above preindustrial levels. They argue that human actions are crucial in steering the Earth System away from this threshold and towards a "Stabilized Earth" pathway, which requires deep cuts in greenhouse gas emissions, enhanced carbon sinks, and adaptation to unavoidable impacts. The article emphasizes the need for a fundamental transformation in human values, behavior, institutions, and technologies to achieve and maintain the Stabilized Earth pathway. It also highlights the importance of building resilience to navigate the turbulent and rapidly changing Earth System.The article explores the risk that self-reinforcing feedbacks could push the Earth System towards a planetary threshold, leading to a "Hothouse Earth" pathway with severe consequences for ecosystems, societies, and economies.
