Global climate models, which are run on some of the world's fastest supercomputers,..The world's surface air temperature increased an average of 0.6 Celsius (1.1F) during the last century according to the Intergovernmental Panel on Climate Change (IPCC).

This may not sound like very..Windows to the Universe, a project of the National Earth Science Teachers Association, is sponsored in part is sponsored in part through grants from federal agencies (NASA and NOAA), and partnerships with affiliated organizations, including the American Geophysical Union, the Howard Hughes Medical Institute, the Earth System Information Partnership, the American Meteorological Society, the National Center for Science Education, and TERC.

To describe the regional climate..Less than 1% of the gases in Earth's atmosphere are called greenhouse gases.

Even though they are not very abundant, these greenhouse gases have a major effect.

Select a temperature range (Normal, Cool, or Warm) and a precipitation amount (Normal, Dry, or Wet) for the coming year. The tree (which you are viewing a cross-section of the trunk of) grows one year's worth, adding a new ring.

Add some rings while varying the temperature and precipitation.

This page does not attempt to cover the details of wood formation that make tree rings possible, but rather provides an overview of common wood characteristics and anomalies that you will need to identify when you are crossdating.

The interactive diagram below demonstrates a very simple model of tree ring growth.

The SKELETON PLOT is one method of crossdating tree rings.
