How Greenhouse Gases Contribute to Global Warming

Impact of Greenhouse Gases on Global Temperature

In recent years, the issue of global warming has become a major concern for the planet. One of the key factors contributing to this phenomenon is the increase in greenhouse gases in the Earth's atmosphere. But how exactly do greenhouse gases lead to a rise in global temperature?

The Greenhouse Effect

Greenhouse gases such as carbon dioxide, methane, and water vapor have the ability to absorb and emit radiation from the sun. When sunlight reaches the Earth's surface, it is absorbed and then re-emitted as heat. Normally, some of this heat would dissipate back into space, allowing the planet to maintain a stable temperature. However, the presence of greenhouse gases in the atmosphere disrupts this balance.

Trapping Heat in the Atmosphere

As greenhouse gases accumulate in the atmosphere, they act like a blanket, trapping heat and preventing it from escaping into space. This trapped heat is then conducted back to the Earth's surface, causing a gradual increase in temperature. The more greenhouse gases there are in the atmosphere, the more heat gets trapped, leading to a rise in global temperature.

Effects of Global Warming

The consequences of global warming are far-reaching and include rising sea levels, more frequent and severe weather events, loss of biodiversity, and disruptions to ecosystems. It is crucial that we take action to reduce greenhouse gas emissions and mitigate the impact of climate change on our planet.

Answer:

Greenhouse gases absorb and emit radiation and less heat dissipates to space

Explanation:

When heat is trapped, it is conducted to the trapped area and gradually heats up its surrounding.
