Which is an effect of global warming? (1 point)

increasing greenhouse gas concentration in air

increasing carbon dioxide in the atmosphere

rising sea level over a period of time

changing seasons every year

rising sea level over a period of time

The correct answer is: rising sea level over a period of time.

The correct answer is: rising sea level over a period of time.

Global warming is primarily caused by increasing greenhouse gas concentrations in the air, with carbon dioxide being one of the main greenhouse gases. However, rising sea levels are an effect of global warming. To understand this, we need to consider the process:

1. Global warming occurs when greenhouse gases, such as carbon dioxide, trap heat in the Earth's atmosphere. This leads to a gradual increase in the average temperature of the planet.

2. As the Earth's temperature rises, it directly impacts the polar ice caps and glaciers. The increased heat causes these ice formations to melt at a faster rate than they can regenerate.

3. The melting ice from polar regions and glaciers adds water to the oceans, causing sea levels to gradually rise over time.

Therefore, one of the effects of global warming is the rising sea level over a period of time. This can lead to numerous negative consequences, including coastal erosion, loss of habitats for certain species, and increased vulnerability to storm surges.
