Global warming is the main reason for the melting of ice-sheets.
Explanation:
Global warming refers to the increase in the Earth's average surface temperature due to the increase in greenhouse gases, such as carbon dioxide, methane, and nitrous oxide, in the atmosphere. These gases trap the heat from the sun and prevent it from escaping into space, causing the Earth's temperature to rise.
The rise in temperature has several consequences, including the melting of ice-sheets. Here's how global warming leads to the melting of ice-sheets:
1. Increase in temperature: As the Earth's temperature rises, the temperature of the air and water around the ice-sheets also increases. This causes the ice to melt and flow into the oceans.
2. Rising sea levels: The melted ice from the ice-sheets flows into the oceans, causing sea levels to rise. This can lead to flooding and other coastal hazards.
3. Feedback loop: The melting of ice-sheets can also create a feedback loop, where the exposed dark surface of the ocean absorbs more heat from the sun, causing further warming and melting of the ice-sheets.
4. Climate change: The melting of ice-sheets can also affect the Earth's climate, as it can alter ocean currents and weather patterns.
In conclusion, global warming is the main reason for the melting of ice-sheets, and it has several consequences for the Earth's climate and environment. It is important to take action to reduce greenhouse gas emissions and mitigate the effects of global warming.

Global warming is defined as the average increase of Earth's temperature due to natural as well as human-induced reasons. Global warming increases the average temperature of the Earth resulting in the melting of ice caps.
