Today's global warming is happening at a much faster rate today it did in the warm periods between ice ages over the last million years.

For New Englanders, the saying “as American as apple pie” may as well be “as New England as lobster.” But warming sea surface temperatures from climate change are forcing populations of the American lobster to higher latitudes than ever before—and upending fishing communities on the New England coast.

 

This animated visualization of precession, eccentricity, and obliquity is simple and straightforward and provides text explanations. It is a good starting place to show Milankovitch cycles.

This figure shows the various astronomic cycles that influence long-term global climate cycles (Milankovitch cycles), plotted on the same time scale for easy comparison.

Climate has varied in the past, but today's climate change rate is much more drastic due to human activity. Students explore past climate cycle graphs and compare the cycles with the current rate of change.
