It seems people will have more opportunities to make a rainbow connection because of climate change. A double rainbow over the Hawaiian shoreline. However, rainbows are an important part of human culture throughout history and around the world and are aesthetically pleasing. The authors stopped short of discussing how changes in rainbow occurrence might affect human well-being. Finally, they applied their model to predict present day and future rainbow occurrences over global land areas. The researchers then trained a rainbow prediction model based on rainbow photo locations and maps of precipitation, cloud cover and sun angle. “We had to sort through photos of rainbow artwork, rainbow flags, rainbow trout, rainbow eucalyptus and rainbow foods to find the real rainbows,” Amanda Wong, one of the study’s co-authors who was then an undergraduate student in global environmental science in the School of Ocean and Earth Science and Technology, said in the press release.
