Description:
The terms greenhouse effect, climate change, and global warming are often used interchangeably, yet they really refer to three separate and distinct processes. This activity examines all three and assesses whether Earth's atmosphere is getting warmer. Students will read two articles from the journal of Science that discuss the findings of the Intergovernmental Panel on Climate Change (IPCC) and investigate the bias of both groups of authors. This activity requires the use of two articles from the July 20, 2001 issue of the journal Science.
