Our atmosphere is getting hotter, more turbulent, and more unpredictable because of the ''boiling and churning'' effect caused by the heat-trapping greenhouse gases within the upper layers of atmosphere. With increase of carbon, methane, or other greenhouse gas levels in the atmosphere, our local weather and global climate is further agitated, heated, and ''boiled''. The green house gases such as water vapour, carbon dioxide methane, nitrous oxied, and ozone are causing great impact on life on earth. Due to global warming, the glaciers are melting, causing sea level rise, coastal submergence and frequent natureal disasters. We have to rethink while taking the development projects and help to protect the existing life forms on the earth before its too late because climate change can exetrminate us.
Why is life thereatened on the earth due to global warming?

Explanation

**Step-by-Step Solution:**

1. **Understanding Global Warming**: Global warming refers to the increase in Earth's average surface temperature due to rising levels of greenhouse gases, such as carbon dioxide, methane, and nitrous oxide. These gases trap heat in the atmosphere, leading to a "boiling and churning" effect.

**Hint**: Identify the main cause of global warming and its effects on temperature.

2. **Impact on Glaciers**: One of the significant consequences of global warming is the melting of glaciers. As temperatures rise, glaciers, which are large masses of ice, begin to melt. This melting contributes to rising sea levels.
