Answer:
An increase in atmospheric greenhouse gases are likely to cause many different things. Here are a few examples:
- Greenhouse gases (such as carbon dioxide, methane..) will cause the earth to get hotter. A hotter earth basically means global warming.
- The increased temperature will cause the polar ice caps to melt, which in turn increases sea levels (making some low-lying areas prone to flooding) and destroys habitats for many species (polar bears, for example).
- Extreme weather will become more commonplace, droughts will occur more often.
