What is greenhouse glass made of?

Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.

Why is it called greenhouse?

In short: it is the natural process that warms the Earth's surface. The process is called the greenhouse effect because the exchange of incoming and outgoing radiation that warms the planet works in a similar way to a greenhouse.
