Our transcription: However, between now and the year 2100 there may be a significant increase in sea level due to the so-called "Greenhouse Effect."

Carbon dioxide and water vapor in the atmosphere act like the glass of a greenhouse.

They let in the sunlight but trap some of the re-radiated infrared heat energy.

Without this Greenhouse Effect, the Earth would become too cold to support human life.
