Climate change might accidentally be making more rainbows, and rainbows come from sunlight hitting raindrops at just the right angle, so where there's more raindrops there's generally more rainbows and Today, the average region gets about 117 rainbows per year, although there's fewer by the drier poles and more near the equator. But as the global climate crisis changes weather patterns, the frequency of rainbows in a lot of places is subject to change by the year 2100. Subarctic regions might see two more rainbows per year. In part because melting ice caps will lead to less snow and more rainfall at the poles. Other places like Tibet and Indonesia might gain rainbows too. Thanks to changes in their wet and dry seasons. But areas like Central Africa and Australia might lose rainbows for that same reason, and people near Spain and Brazil might lose rainbows too. Thanks to changes like fewer rainy times or clouds blocking out the sunlight, how this affects the world's leprechaun populations remains to be seen.
