◆ Over the next 100 years the amount of warming could be as low as 1 to 1.5 degrees Celsius, but it could be as high as 5 degrees Celsius. ◆ An increase of five degrees would be a ___________. catastrophe
plants, especially during cold
weather.
• How does it work? The air inside is warm because the glass traps the heat from the sun and keeps it from escaping. This makes the greenhouse heat up and so the plants can grow throughout the cold period.
