Teaching Tips

Educators using this set of visualizations could consider using it to introduce climate change with the understanding that natural variation in temperature fluctuations cannot account for the upward trend in global temperatures.

Could be used for homework for students to look at natural causes of global temperature fluctuation before a lesson on global warming and human causes of global temperature change.

Graphics may require more background knowledge than students have acquired.

References are linked to reputable resources that provide the end users a good visual with supporting documents.

For younger students, educator may need to explain what "trends" are to students: "What constitutes a trend?" "How many years?"
