Over 1 million species are at risk due to climate change and in 2020 natural disasters caused over $210bn in damage. Global temperatures are rising, currently around 1.2°C higher than pre-industrial levels (1880–1900), increasing heat waves, droughts and wildfires. Surface water temperatures are rising, causing coral bleaching, and melting ice caps, further contributing to global warming, known as a positive feedback loop, which will be irreversible by 2030.
