The terms 'global warming' and 'greenhouse effect' are often used interchangeably, but they refer to distinct yet closely related environmental phenomena. Global warming refers to the gradual increase in Earth's average temperature, while the greenhouse effect is a natural process that warms the Earth's surface.
The sun emits solar radiation, a portion of which reaches the Earth's surface. Some of this radiation is reflected back into space, while the rest is absorbed by the Earth's oceans and landmasses, causing them to heat up. Greenhouse gases in the atmosphere trap this heat, creating a 'blanket' that warms the Earth to a temperature capable of supporting life. However, an excess accumulation of these gases can trap more heat than necessary, leading to an increase in Earth's average temperature - a phenomenon known as global warming.
Understanding the Differences Between the Greenhouse Effect and Global Warming
While they are related, the greenhouse effect and global warming are not the same thing. Let's delve into their differences.
Greenhouse Effect
Global Warming
Definition
The greenhouse effect refers to the natural process whereby heat from the sun is absorbed by the Earth's surface and then radiated back into the atmosphere, where it is trapped by greenhouse gases.
Global warming refers to the long-term increase in Earth's average temperature, primarily caused by human activities that increase the concentration of greenhouse gases in the atmosphere.
Temperature Implications
The greenhouse effect is essential for maintaining Earth's temperature and supporting life. Without it, our planet would be too cold.
Global warming leads to a rise in Earth's average temperature, which can have severe impacts on the planet's climate, ecosystems, and human societies.
Causation
The greenhouse effect is a natural process resulting from the presence of greenhouse gases in the atmosphere, such as carbon dioxide and methane, which trap heat radiated from the Earth's surface.
Global warming is primarily caused by human activities that increase the concentration of greenhouse gases in the atmosphere, such as deforestation, industrial processes, and the burning of fossil fuels.
In conclusion, while the greenhouse effect and global warming are closely linked - with the former being a natural process and the latter a consequence of human activities - they are distinct phenomena with different implications for our planet.

What is the difference between Greenhouse Effect and Global Warming?
The Greenhouse Effect refers to the trapping of the sun's warmth in the planet's lower atmosphere due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface. Global warming, on the other hand, is the long-term warming of the planet.
What causes the Greenhouse Effect and Global Warming?
The Greenhouse Effect is caused by the atmospheric accumulation of gases such as methane and carbon dioxide which contain some heat emitted by the earth's surface. Global Warming is primarily caused by an increased concentration of greenhouse gases in the atmosphere, majorly contributed by human activities like deforestation, burning of fossil fuels, etc.
