Additional people at risk of extreme poverty with high climate adaptation challenges, 2030. Difference in the projected number of people living in extreme poverty between the baseline (business-as-usual) scenario and the projected scenario characterized by low economic growth coupled with low educational attainment levels and high global population growth at the global level; this results in high climate mitigation and adaptation challenges. The international poverty line is measured as living on less than $1.90 per day, which adjusts for inflation and cross-country price differences.
