Appearing more frequently, rainbows and various other phenomena stand as the clearest warnings of climate change.
The wonders of astronomy or breathtaking natural phenomena appearing worldwide may not be unfamiliar to many. Whether witnessed firsthand or observed through recorded images, these phenomena never fail to captivate with their beauty.
However, not everything is as beautiful as it seems. Alongside the awe-inspiring phenomena, many natural scenes occur due to the impact of climate change. Though not yet entirely clear, these also serve as a warning about the negative effects of environmental changes on the planet and human atmosphere.
1. Rainbows
Traditionally known as symbols of hope and new beginnings, rainbows are increasingly linked to climate change. Recent observations note a rising frequency of rainbow occurrences in the Arctic.
Accordingly, this is due to the Earth warming up, causing a reduction in snowfall. Instead of snow, large 'water drops' enhance the brightness of the arcs. Additionally, the Amazon rainforest, where rainbows frequently appear, is predicted to experience more frequent droughts due to both shrinking area and the impact of climate change on tropical rainfall, resulting in fewer and thinner clouds that intensify solar heat.
2. Glowing Beaches
Images of waves emitting beautiful blue light have sparked fairy-tale fantasies online, resembling scenes from a magical world. In reality, this phenomenon is created by Noctiluca algae, organisms that convert their chemical energy into light energy when washed ashore.
Unfortunately, maritime experts state that this occurrence is a climate change indicator and could negatively impact deep-sea fishing activities.
According to Indian Express, Dr. Pravakar Mishra, an expert in Coastal Management and Coastal Processes at the National Centre for Coastal Research (NCCR), mentions that this bioluminescent phenomenon may stem from heavy rainfall and wastewater discharge into the sea.
'The proliferation of bioluminescent organisms can occur due to heavy rainfall and wastewater discharge into the sea. Factors such as wind patterns and ocean temperatures also influence the appearance of bioluminescent waves,' - Mishra added.
3. Frozen Gas Bubbles
Beneath the thick layer of ice, floating bubbles have created a unique spectacle that captivates many. However, the story of their formation is less enchanting. These gas bubbles form when bacteria decompose organic matter at the lake bottom, releasing methane gas to create the bubbles.
During winter, when the water freezes, the trapped bubbles form enchanting 'magic orbs' reminiscent of scenes from the movie Frozen. Yet, as these bubbles thaw and burst in spring, they release a significant amount of methane into the atmosphere, impacting our climate.
4. Pink Snow
Appearing in the region known as the Dark Zone of Greenland, the algae species named Ancylonema nordenskioeldii turns snow into a beautiful pink hue.
However, this area is also recognized as highly impacted by climate change. Scientists are investigating how these algae darken the ice, causing ice blocks to absorb heat and melt faster.
This resembles a reciprocal interaction. When algae appear, the ice will melt faster. Melting ice provides water and air for algae growth. The more the snow melts, the more algae appear, creating a pink layer on the white snow at an elevation of 2,618 meters.
