Whether we realize it or not, each year the heat seems to get more intense. And that’s not just our imagination, it’s a fact.

According to data from the National Centers for Environmental Information, 2024 was the hottest year of the 21st century so far. Over the past decade, global temperatures have broken record after record.

We’re facing the reality of global warming, and its effects are becoming more visible than ever. So, what can we do about it? Let’s explore some practical solutions in this article.

Why Global Warming Needs to Be Addressed Now?

Global warming isn’t just an environmental issue. It’s a direct threat to human life and all living beings on Earth.

A rise in greenhouse gases such as CO₂, methane, and nitrous oxide in the atmosphere causes an increase in global temperatures. These gases trap the sun’s heat and cause Earth’s temperature to rise.

Human activities like burning fossil fuels, deforestation, and industrial pollution have accelerated this process.

And we’re already witnessing the consequences:

• Melting polar ice caps, leading to rising sea levels
• More frequent and intense heatwaves
• Widespread wildfires
• Droughts and flash floods
• The spread of diseases like malaria and dengue

Ignoring this issue will only worsen the long-term damage. That’s why action needs to be taken now. The longer we wait, the harder it will be to reverse the damage.

5 Practical Ways to Tackle Global Warming

There are many simple things we can do, starting from our daily habits, that contribute to fighting global warming.

While these actions may not bring instant results, they can help slow down the impact over time.

Here are five things you can start doing today:

1. Save Electricity Wherever You Can

Many people don’t realize that electricity use contributes significantly to global warming.

Most electricity is still produced by burning fossil fuels, which release carbon dioxide (CO₂) into the atmosphere. This buildup of emissions is one of the main causes of global warming.

That’s why reducing electricity consumption, even in small ways, like turning off lights when not in use, can lower energy demand and help reduce emissions.

2. Reforest and Replant Trees

Widespread deforestation has stripped trees of their natural role as carbon absorbers. With fewer trees, more CO₂ stays in the atmosphere, intensifying the greenhouse effect.

Tree planting, or reforestation, is a powerful way to balance CO₂ levels. Trees absorb carbon dioxide and release oxygen, helping to regulate the climate, increase humidity, and lower temperatures.

3. Recycle Waste Properly

Organic waste sent to landfills breaks down and produces methane, a potent greenhouse gas. Without proper waste management, this buildup can worsen global warming.

That’s why it’s important to separate organic and non-organic waste before disposal.

Organic waste, like food scraps or dry leaves, can be composted or turned into biogas. Meanwhile, non-organic waste like used plastic bottles can be recycled or repurposed, for instance, into pots or storage containers.

4. Embrace a Minimalist Lifestyle

Overconsumption drives mass production, which generates more waste and increases greenhouse gas emissions. To reduce environmental damage, it’s time to embrace minimalism.

Start by choosing durable, reusable products, for example, replacing single-use plastic water bottles with stainless steel ones.

5. Use Fuel More Efficiently

Fossil fuel-powered vehicles are a major source of CO₂ emissions. Now, imagine the scale of pollution if everyone relied solely on private transportation every day.

One of the simplest ways to help reduce this impact is by using public transportation. It’s more energy-efficient, environmentally friendly, and also helps cut down on traffic congestion.

The Role of LNG in Reducing the Impact of Global Warming

Coal is still the dominant energy source in many parts of the world, but it’s also one of the dirtiest. Burning coal releases large amounts of carbon dioxide, accelerating global warming.

That’s why switching to cleaner, more sustainable energy sources is crucial, and this is where LNG (Liquefied Natural Gas) can play a vital role.

According to Wood Mackenzie, LNG emits about 50% less CO₂ than coal when used for power generation. That means using LNG can significantly reduce carbon emissions and slow the pace of global warming.

While LNG is not a zero-emissions fuel, it can serve as a transitional energy source as we move toward fully renewable energy systems.

If managed and used responsibly, LNG can help reduce our dependence on fossil fuels and support climate recovery efforts.

We often assume that waste marks the end of a cycle. In reality, there’s great potential for energy production if organic waste is processed properly.

Organic waste comes from various sources, ranging from household trash to agricultural residues. Since it decomposes easily, this type of waste can be turned into renewable energy sources such as biogas.

So, what kinds of organic waste can be transformed into energy? Let’s explore the answers in this article.

Why Can Organic Waste Be Used as an Energy Source?

Nearly all human activities generate organic waste. Without proper management, the accumulation of this waste can become a serious problem.

Yet behind what we consider mere trash lies the potential to become biogas, a clean, renewable energy source.

Both liquid and solid waste from households, farms, and industries can be converted into biogas through anaerobic digestion, a process that breaks down waste without oxygen.

On a larger scale, biogas can replace fossil fuels, helping reduce greenhouse gas emissions and promoting a cleaner, more sustainable energy future.
