The Historical Context

For over 150 years, fossil fuels have been the primary driver of global human development and industrialization. While they have lifted billions from poverty, the unyielding increase in consumption has caused immense environmental strain. Historical records derived from ice cores show that atmospheric CO₂ never surpassed 300 parts per million in the 800,000 years prior to the 20th century. Today, human energy consumption has pushed that number beyond 420 ppm, accelerating the greenhouse effect at unprecedented rates.

Future Projections & The Gap

The International Energy Agency projects that even if all current national energy and climate pledges are fulfilled on time, the world will still fall short of limiting global warming to 1.5°C above pre-industrial levels. Bridging this gap requires not just switching the source of our energy generation, but radically decreasing overall energy waste through efficiency. Phasing out unabated coal power and tripling renewable capacity by 2030 are the absolute baseline requirements to secure a livable future.
