“Climate change is no more a doomsday prophecy; it’s a reality.” — Astrid Nøklebye Heiberg
Time is changing, and so is the climate. There was a time when the earth followed a predictable seasonal cycle—winters, summers, and monsoons, arriving like clockwork. But now, that natural rhythm is breaking down. We see floods where there shouldn’t be any, droughts stretching for years, rains at odd times, and even new diseases surfacing. These are all symptoms of climate change.
Unlike a sudden event, climate change is a gradual process. It didn’t seem to cause major disasters at first, but now, its effects are all around us. And if we don’t act soon, we’ll be facing even greater challenges in the future. So, what exactly is causing this disruption, and what can we do about it?
Critical Causes of Climate Change
The root causes of climate change stem from human activities that disrupt the earth’s balance. Let’s break down the key contributors:
1. Pollution
The excessive release of harmful substances into the atmosphere, water, and soil has drastically altered the environment. Industrial waste, vehicle emissions, and plastic pollution are significant culprits.
2. Overpopulation
As the world’s population grows, so does the demand for resources. More people mean more energy consumption, food production, and waste, which only accelerates the environmental impact.
3. Deforestation
Cutting down forests reduces the earth’s ability to absorb carbon dioxide (a greenhouse gas) and destroys biodiversity and the natural balance of ecosystems.
4. Greenhouse Gases
The most significant cause of climate change is greenhouse gases. Greenhouse gases like carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O) trap heat in the atmosphere, causing the earth’s temperature to rise.
The Growing Impact of Greenhouse Gases
Greenhouse gases have been building up in our atmosphere for decades and are now reaching dangerous levels. Let’s explore two of the biggest offenders—CO2 and N2O—and what we can do to reduce their impact.
⭐ Carbon Dioxide (CO2)
- Natural Sources: Decomposition of organic material, respiration, and ocean releases.
- Human Sources: Deforestation and burning fossil fuels (coal, oil, and natural gas) are the main contributors to excess CO2 in the atmosphere.
The chart below shows CO2 emissions continent-wise, with Asia leading the way, projected to contribute 1,400 metric tons of CO2 by 2025. This alarming trend reflects the rapid industrialization and energy consumption in that region.
How can we reduce CO2 emissions?
The solution lies in switching to sustainable energy sources. Solar energy, for instance, is a clean and renewable option that significantly reduces pollution. Additionally, transitioning to electric vehicles (EVs) can reduce fossil fuel consumption, reducing our carbon footprint.
⭐ Nitrous Oxide (N2O)
- N2O is often overlooked but is a far more potent greenhouse gas than CO2. In fact, it’s 300 times more harmful in terms of trapping heat in the atmosphere. Worse still, it contributes to ozone layer depletion.
Where does N2O come from?
- Natural Sources: N2O is released during lightning storms.
- Human Sources: It is also emitted from fossil fuel combustion and from nitrogen-based fertilizers used in agriculture.
How can we manage N2O emissions?
Better fertilizer management is crucial in reducing N2O emissions. Farmers can optimize fertilizers’ type, timing, and placement to minimize emissions. And, just like with CO2, moving away from fossil fuels and toward clean energy can significantly cut N2O emissions.
Global Efforts to Combat Climate Change
Fortunately, people and organizations around the world are waking up to the reality of climate change. Numerous groups are working hard to reverse the damage we’ve done, including:
- Earth System Governance Project (ESGP): Focuses on sustainable development and governance to tackle climate issues.
- Global Green Growth Institute (GGGI): Promotes economic growth through green solutions.
- International Union for Conservation of Nature (IUCN): Works on protecting natural resources and biodiversity.
While these international initiatives are crucial, local action is equally important. Individual efforts—like saving electricity, using renewable resources, reducing plastic use, and limiting fossil fuel consumption—can collectively make a huge difference.

Small Steps, Big Change
The biggest challenge in combating climate change is that it can seem too vast for one person to influence. However, when millions of people take small, consistent steps, the collective impact can be transformative. Here are some practical actions you can take right now to make a difference:
1. AMG Action: “Avoid, Minimize, and Generate”
Solar energy pioneer Chetan Singh Solanki advocates for a systematic approach to combat climate change through his AMG principle—a powerful framework that helps individuals contribute effectively to sustainability:
- Avoid: Focus on avoiding wasteful practices and excessive energy consumption. This includes turning off lights and devices when not in use, reducing unnecessary travel, and consciously avoiding overconsumption of goods and resources.
- Minimize: If energy consumption cannot be avoided, minimize it. Opt for energy-efficient solutions, like switching to LED lighting, using high-efficiency appliances, and cutting down on food waste by consuming mindfully.
- Generate: Wherever possible, generate your own clean energy. Installing solar panels on your home or supporting solar energy initiatives can drastically reduce dependence on fossil fuels, helping to generate a sustainable energy future.
This systematic approach encourages everyone to make conscious choices that gradually lower their carbon footprint.
2. Support Sustainable Brands
Every purchase you make has an environmental impact. Choose to support brands and companies that prioritize sustainability, practice ethical sourcing, and promote green business practices. By voting with your wallet, you help create a demand for eco-friendly products and encourage other businesses to adopt greener practices.
The Road Ahead: A Call to Action
The key to fighting climate change is to act now. We can’t afford to wait until the damage is irreversible. While governments and corporations have a significant role, individual actions also matter. Every bit counts—whether it’s reducing your carbon footprint, spreading awareness, or supporting green initiatives.
The earth is showing us warning signs, and we must listen. It’s not too late to make a change. If we take responsibility and work together—locally and globally—we can slow down climate change and create a sustainable future for the generations to come.
Remember, the smallest actions today can lead to a greener, healthier planet tomorrow.
Final Thoughts: It’s Time to Go Green
We’ve explored the critical causes of climate change and some tangible solutions to reduce its effects. The time to act is now, and the solutions, though simple, can have a massive impact if adopted widely. Switching to solar energy and reducing greenhouse gas emissions are not just environmental options—they’re necessities.
So, let’s not wait for the next disaster to remind us. Let’s start today.
