Is the Planet Earth destabilizing?

I woke up at 6 am, thanks to the relentless loud alarm. I turned it off, got up from my bed, stepped on the floor mat and the dampness hit me! The soggy floor drove away my sleepiness. I carefully trotted to the hallway and noticed water dripping down the electric point on the wall, flooding the surface. I was shocked. Immediately, I moved the table and started wiping and drying the floor.

I rushed to the first floor to check with my neighbour about the situation, and they were busy cleaning their house too. The water seemed to have entered all corners of their apartment and they had a tough time wiping it dry.

All of this was due to the heavy rain that poured at midnight from 12 to around 5 in the morning, mid-February this year. The downpour was heavy and ferocious. It left the entire city stranded, the whole day! And it was neither monsoon nor had a low pressure developed in the Bay of Bengal. Then what could be the reason? Climate change?? It was a possibility, given the time of this incident – February – which is usually the onset of summer.

During the same period, there was a deluge caused due to a glacier melt at the Rishi Ganga River in Uttarakhand. It washed away two major hydroelectric power projects constructed across the river. This was attributed to global warming by experts, who say that inconsistent weather patterns lead to an increase in the thermal profile of ice, making it more vulnerable to melting.

We have been hearing about this phenomenon, climate change for a while now. It is quite popular. Much has been discussed and debated on what lead to the change i.e., is it natural, or anthropogenic? The latter topped the charts. And the question we strive to answer is, when will it stop… Or What can be done to make it stop…

Professor Johan Rockstrom, an internationally recognized scientist working on global sustainability issues, delves into much broader questions like - Do our planets have boundaries? Can it be defined? Is the planet earth destabilizing? What does it take to stabilize? (Check his TED talk here)

Before exploring that, we need to know when does the earth stabilize. Professor, in the recently released Netflix documentary – Breaking Boundaries – explains that it all started during the Holocene era when the earth’s temperature stabilized paving the way for the existence of life forms. Along with all other kinds of life, came Humans, who not just lived and enjoyed stability but also took advantage of it to satisfy their own greed. This went beyond the boundaries of our planet causing various troubles.

Now, you might be thinking – What is a planetary boundary?

The planetary boundary is a novel concept developed and published by the international team of 18 researchers in the year 2009. According to the paper, there are nine planetary boundaries, and they are as follows,

  1. Climate change
  2. Change in biosphere integrity (biodiversity loss and species extinction)
  3. Stratospheric ozone depletion
  4. Ocean acidification
  5. Biogeochemical flows (phosphorus and nitrogen cycles)
  6. Land-system change (for example deforestation)
  7. Freshwater use
  8. Atmospheric aerosol loading (microscopic particles in the atmosphere that affect climate and living organisms)
  9. Introduction of novel entities (e.g., organic pollutants, radioactive materials, nanomaterials, and micro-plastics).

The stability of our planet earth, as the professor states in the documentary, is mainly due to these nine processes. These elements are the reason, our planet is intact. Any change in this would greatly affect our planet, and in turn, us.

“Four of nine planetary boundaries - climate change, loss of biosphere integrity, land system change, altered biogeochemical cycles (phosphorus and nitrogen) – have crossed the tipping point due to unfavourable human activities,” says the researchers and further adds, “Two of these, climate change and biosphere integrity, are core boundaries. Any change in these two would drive the Earth System into a new state.”

Planetary Boundaries do not dictate how human societies should develop but they can aid decision-makers by defining a safe operating space for humanity. - Katherine Richardson, co-author

Until now, it was all ‘climate change and ‘global warming to us. But the contention that that is just one among the others, is a great revelation. Researchers have brought together all the separate processes under one roof which would make human beings to think about what we have done, are doing, and will do in the future.

And all of this has been beautifully narrated in this documentary – Breaking Boundaries – in a tone that is simple, unambiguous, persuasive, and provoking. 

I hope, it attracts the world leaders at least now, to act.

While I was giving the finishing touch to this draft during the month of June 2021, I heard it again. The feeling of Deja Vu struck me. Its raining! Nonstop!

  1. Well written ji 👌👏.
    Interesting to learn that there are parameters that define the planetary boundaries. True that the Earth's processes that sustain life are affected and leading to instability.

Can Forests be taken for granted?

Early morning breeze swaying alongside us. It was cold yet adaptable  and   pleasant . Coming from the place where only three seasons are predominant – hot, hotter, hottest – people embrace winter like never before. Little  did they realise that winter is really difficult to withstand and a significant reason to worry upon. Nevertheless, that’s what I did too in Kodaikanal – enjoying the cold weather conditions. The temperature was under 15 degrees in the morning and was well-suited for a lovely walk. Way to Wilderness I took a stroll along with a few of my nature lovers. The high rise trees, mostly non-native, standing erect on both sides of the rough path. Standing beneath them were a few native Shola trees like Native Olive , Nilgiri Elm , Matchbox tree, etc., which were once abundant in Kodaikanal but now exist only in small patches. Thanks to the invasive Eucalyptus, Pine, Lantana and Accacia trees (and many more) that took over the forest just like we (humans) do for

Kazhuveli Wetlands – Fresh and Endless Wilderness

Lone Pond Heron getting ready for hunt Sunday morning are best suited for travel and explorations due to less congested roads. People sleep and hence no traffic. What more do you need than an empty road in the winter morning? Grabbing the opportunity like a hungry cat, we decided to visit the nearby wetlands – Kazhuveli – located around 16 kms north of Puducherry along the east coast. We hit the East Coast Road (ECR) early in the morning. Winter was not at its peak but pleasing. There is something beautiful about winter mornings, especially in Puducherry. While fog keeps you cold, the warm sea breeze stimulates your senses. It’s just enchanting. Riding in ECR was fun but its short-lived as we took a detour into the village after crossing Anumanthai toll. The roads were narrow and rugged, giving us an adventurous ride. After passing through some sharp turns and a lot of humps, a water body caught our eyes. It wasn't as massive as I visualised. Wetlands flou
