Climate Justice and Equity: The Bathtub Analogy for Global Emissions #2127879 (License: Personal Use)

This visual uses a bathtub metaphor to explain the limited atmospheric capacity for greenhouse gases, showing key CO₂ thresholds (280 ppm pre-industrial, 400 ppm current, 450 ppm dangerous). It contrasts historical emissions by developed nations with current contributions from developing countries, highlighting ethical dilemmas around climate responsibility and adaptation. Red arrows emphasize the disproportionate burden on vulnerable populations and the urgency of equitable climate action.

Used in climate education, policy briefs, and environmental justice advocacy to communicate complex equity issues in accessible terms; targets educators, policymakers, and activists seeking to explain fairness in emissions allocation.
