How does the greenhouse effect contribute to climate change?

The greenhouse effect plays a critical role in contributing to climate change primarily by trapping heat in the atmosphere. This phenomenon occurs when certain gases, known as greenhouse gases (such as carbon dioxide, methane, and nitrous oxide), accumulate in the Earth’s atmosphere. They let sunlight in but prevent some of the heat that the Earth emits from escaping back into space, much like the glass walls of a greenhouse allow sunlight to enter while retaining warmth.

As human activities increase the levels of these greenhouse gases—primarily through the burning of fossil fuels, deforestation, and industrial processes—the natural balance of the greenhouse effect is disrupted. This leads to an overall warming of the planet, which results in various changes in climate patterns, including more frequent extreme weather events, rising sea levels, and shifts in ecosystems.

Understanding this process is essential, as it highlights the mechanisms by which human action can lead to significant and lasting changes in our climate, reinforcing the necessity for efforts to mitigate these impacts.
