Global warming is causing the Earth's temperature to rise, mainly due to the greenhouse effect. This can harm human health directly and indirectly by causing various health problems and threatening access to clean air, water, food, and shelter. Human activities are the main cause of rising temperatures, which could increase by 2.5 to 10.4 degrees in the next century. Sea levels are also rising due to global warming, with predictions of a 7 to 23-inch rise by 2100 and continuing for the next 1,000 years. It's important to spread awareness about the negative effects of global warming on human health, and nurses play a crucial role in educating the public about it.
