Global temperature projections with increasing and decreasing greenhouse gas emissions.

This animation shows predicted changes in temperature across the globe, relative to pre-industrial levels, under two different emissions scenarios in the COP 17 climate model. The first is with emissions continuing to increase through the century. The second is with emissions declining through the century.

Teaching Tips

There is no narration to this animation, so the educator will need to provide the context and explain what is being shown.

About the Science

The model shows that by the end of the century, the global average temperature rise would be just above 4 degrees C with increasing emissions, and just over 2 degrees C with decreasing emissions (compared to pre-industrial levels).

The animation is produced by the United Kingdom's national weather service.

Comments from expert scientist: These changing patterns show how temperature change would occur according to two scenarios of global warming until the year 2099. The results are very significant, both lower and higher gas amounts. The scenarios are from early model runs. There is no view of the high southern latitudes including the Antarctic continent.

About the Pedagogy

Requires some prior explanation of the IPCC emissions scenarios.

A small amount of information on the two scenarios used is given in the text below the video.

Technical Details

Visual quality sufficient for projection, although recommend HD view.
