Impact of Climate Change on Rainbows

The video discusses how climate change may inadvertently increase or decrease the frequency of rainbows in different regions. Rainbows form when sunlight hits raindrops at a specific angle, so more rain can lead to more rainbows. By 2100, subarctic regions might see more rainbows due to increased rainfall from melting ice caps, while areas like central Africa and Australia might see fewer due to altered wet and dry seasons. Changes in cloud cover and rainfall patterns could also affect rainbow visibility in places like Spain and Brazil.
