<human>:  I’m participating in a debate about climate change and need some facts and statistics about the subject.
<bot>: According to the World Resources Institute, the planet has warmed by 1.1°C since the Industrial Revolution, and is on track to warm by 3°C to 5°C by the end of the century. Melting Arctic sea ice has raised global sea levels by 20 cm and caused glaciers to shrink drastically. Warming temperatures are also destabilizing habitats, leading to species extinction and changes to the ocean's food web. Climate change is further affecting ecosystems and human health, with increased risks of extreme heat, drought, floods and other natural disasters. The World Health Organization estimates that 248 000 deaths are attributed to climate-related health impacts in 2016.
