1 Minute Speech on Green House Effect In English

Good morning to one and all present here. Today, I’ll be giving a short speech on the topic of the Green House Effect. 

Google defines the greenhouse effect to be “the trapping of the sun’s warmth in a planet’s lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet’s surface.” 

In layman’s terms, the greenhouse effect refers to the process by which greenhouse gases absorb the thermal radiation emitted by a planet’s- here, the Earth’s- surface and re-radiate it in every direction. Because this radiation occurs on the surface and lower atmosphere of Earth, it consequently increased its average surface temperature. Common greenhouse gases which do this would be carbon dioxide, methane, and ozone. 

While this natural process is a good thing, increased emission of greenhouse gases is dangerous. Increased heating could result in dire consequences such as the thawing of glacial masses, excessive flooding, and even violent hurricanes.

Thank you.
