Air and Global Warming: Understanding Greenhouse Gases and Our Role

The Earth’s atmosphere has long helped maintain temperatures suitable for life and the natural world. Today, however, even small shifts in its composition are causing noticeable changes in the global climate, bringing the planet to a critical point. How is the air around us linked to global warming, and what role do greenhouse gases play in this process?

What Is Causing Global Warming?

Global warming is primarily driven by rising levels of greenhouse gases in the atmosphere. Over the past 150 years or so, the Earth’s average temperature has risen by about 1.1℃, and could rise by as much as 4.4℃ if current trends continue.

Are Greenhouse Gases Harmful to the Environment?

Greenhouse gases such as carbon dioxide and methane are not inherently harmful.
In fact, they are essential for keeping the planet warm enough to support life—without them, average temperatures would fall below 0°C. However, when these gases exceed a balanced range, they begin to disrupt the climate system.

Why Have Greenhouse Gas Levels Increased?

Before the Industrial Revolution, greenhouse gas levels remained relatively stable, maintaining conditions suitable for life. Since then, growing energy use has led to a sharp increase in carbon dioxide emissions. At the same time, deforestation has reduced the number of trees that absorb carbon dioxide, allowing more of it to accumulate in the atmosphere.

How is Global Warming Affecting Our Lives Today?

Rising temperatures impact more than just the climate. They contribute to more frequent extreme weather events such as heavy rainfall, which can lead to natural disasters. These changes also create challenges like unstable food supplies, higher costs of living, and water shortages. Global warming is no longer a distant issue—it is already affecting daily life.

What We Can Do to Reduce Global Warming

Air conditioners are an important part of everyday life and account for a large share of household electricity use. Using them more efficiently can help reduce energy consumption and lower their impact on global warming. Simple steps such as setting the temperature to around 26°C, cleaning filters regularly, and unplugging units when not in use can make a meaningful difference. These actions not only help address global warming but can also reduce electricity costs.

Taking Action to Lower Greenhouse Gas Emissions

Once global temperatures rise, it can take hundreds of years for them to return to previous levels. Preventing further increases requires consistent effort from each of us. Guided by its management philosophy, Daikin continues to contribute to a more sustainable society through its technologies and business activities.

Global warming is driven by rising levels of greenhouse gases such as carbon dioxide.
These gases originally helped maintain temperatures suitable for life on Earth.
Since the Industrial Revolution, average temperatures have risen by about 1.1℃ as greenhouse gas levels have increased.
The effects are already visible, including extreme weather and pressures on food and water resources.
Everyday actions, such as using air conditioners efficiently, can help reduce environmental impact while lowering energy costs.
