More Rainbows could be a silver lining for climate change

New research suggests that climate change could bring more rainbows with it. Novel studieswhich was published in the journal by a team of researchers Global environmental changeestimates a roughly 4 to 5% increase in the average number of global rainbow days by 2100. This is the number of days per year with conditions favorable for the formation of a rainbow.

Of course, global climate change is expected to have significant downsides, including more forest fires, droughts, extreme temperatures, floods, and climate refugees, to name a few issues. We should not underestimate these dangers. However, it should also be noted that there can be positives among the negatives, including benefits to our natural environment and human well-being.

The study’s authors used a unique research strategy that involved downloading more than 100,000 rainbow images from the photo-sharing website Flickr and then capturing information about the locations and local weather conditions using machine learning and other methods.

Currently, the global distribution of rainbow conditions is far from uniform. Areas around the poles and deserts, such as the Middle East, tend to experience fewer rainbow days than more coastal, tropical areas such as southern Liberia or eastern Nicaragua.

More rainbows could materialize in the future due to factors such as increased precipitation and reduced cloud cover. The areas most likely to get rainbow days are those at higher latitudes and high altitude. A good example is the Tibetan Plateau. Some of these areas are associated with smaller human populations. However, the authors still predict that the average person will have more opportunities to see a rainbow in 2100 compared to 2000.

Overall, 21 to 34% of the country’s areas are projected to lose rainbow days, while 66 to 79% will gain rainbow days, meaning that not all areas will be affected equally, highlighting the substantial redistribution of the rainbow.

The implications go beyond scenery. The authors of the study note that rainbows inspire connection with nature, thereby contributing to human well-being.

Rainbows have a special place in cultural myths and folklore. in Estonian mythology, for example, there are stories of a rainbow snake that sucks up water on the ground and then spits it back out on the ground in the form of rain. In the Bible, the rainbow served as a symbol of God’s promise of protection to Noah after the great flood. And of course, who could forget the pot of gold said to lie at the end of the rainbow, guarded by a lucky leprechaun?

Rainbows also have connections to bridges and archers’ bows. Recently, the rainbow has become a symbol of gay pride, representing openness and tolerance. This means that rainbow associations are not uniformly positive. The authors note that in some cultures the rainbow is a sign of foreboding, such as in parts of Southeast Asia, where it is associated with a child-eating demon.

With climate change comes anxiety and fear about the future, and this study won’t change that. However, it is somewhat of a relief to find research emphasizing the silver lining, even though we expect the overall effects of global warming to be decidedly negative. Who among us does not get excited at the sight of a rainbow? Regardless of the challenges, there are several reasons why we should be looking, literally.
