Impact of Climate Change on the World

• Advanced countries like Australia and the USA release 20 tonnes of CO2 per capita per year, contrasting with Low Income Developing Countries (LIDCs) like Zambia and Tanzania, responsible for 0-2 tonnes per capita per year
• Some LIDCs, emitting low greenhouse gases, face severe impacts; the Maldives, low-lying islands, experience rising sea levels
• Global warming contributes to water stress, with a projected 1 billion people lacking sufficient water by 2025
• Ecosystems worldwide face threats; in the Arctic, melting ice sheets jeopardize the polar bear population, while butterflies migrate north due to warming habitats
• Climate change exacerbates existing social problems such as poverty, inequality, and conflict.
