Solar radiation travels through the earth's atmosphere and warms the planet's surface. Greenhouse gases like carbon dioxide in the earth's atmosphere reabsorb the heat and warm the planet. The amounts of greenhouse gases have been increasing over the past century, causing the earth's surface temperature to increase. This gradual temperature change is thought to have many negative environmental consequences.

increase in the sea level and droughts

Explanation:

The increase in the temperature of the atmosphere results in many catastrophic changes. These changes upset the life on the earth. For example, the increase in the temperature causes the surface if the polar ice to be warmer. As the ice becomes warmer, it melts and increases the level of the water in the sea. This causes islands to be covered. Thin addition, the coastal areas are also in danger of flooding. In addition, the increase in the temperature causes the droughts. These can be due to floods or desert conditions. Lastly, this causes fires, e.g. Australian fires.
