Climatic Changes

Investigate the greenhouse effect and global warming with this weather worksheet: scholars describe the seasonal variations of temperature and day length at its greatest and its least. Then they describe the effects of El Nino and how scientists estimate what Earth's climate was like in earlier geologic eras. While this requires little to no critical thinking, it does serve to reinforce climate-related concepts. Intended for use with Glencoe McGraw Hill Science Voyages text.
