The UV index is a measure of the intensity of ultraviolet (UV) radiation from the sun at a particular place and time. It is a scale that helps people understand the strength of the sun's UV rays and take appropriate precautions to protect their skin and eyes from potential damage.
In relation to climate change, the UV index can be affected by various factors such as ozone depletion and changes in atmospheric conditions due to global warming. Climate change can lead to shifts in cloud cover, air pollution, and changes in the ozone layer, all of which can influence the amount of UV radiation reaching the Earth's surface. Understanding the UV index and its changes due to climate change is important for public health and safety measures.
