This is a fabulous visualization from NASA. There are many similar resources but what intrigues me is that this is quick and direct and there’s no question about the data as it’s displayed over time.

You select your concern – Sea Ice, Sea Level, Carbon Dioxide, or Temperature…
… and then you’re presented with the visualization.
Here is the visualization for world temperature.
The first time through, you’ll probably be tempted to just press play and watch the visualization from beginning to end.
The power though is that there’s a little scrubber bar that lets you control your walk through time. This would allow you to stop at a particular year to discuss in class what was happening at that time.
It’s a quick and clear to use resource.
