2,000 Years of Continental Climate Changes

This infographic, found on Cool Infographics, shows how the climate has changed over the past 2,000 years in seven regions of the world (nearly all five continents, but not quite). Each color change represents the 30 year mean, and the increase and decrease of the temperature over time can be viewed. How do you think the mean was found before modern technology?

First of all, the infographic shows that North America and Antarctica share a similar temperate trend, and the five remaining regions share an opposite trend. On top of this, the arctic regions are experiencing a warm up and the other regions are showing a cool down. What could cause each of these phenomenon?

Share this with your classroom while studying global warming and other long term weather changes. This is a good example of what global warming can lead to. However, it can also be noticed that the major changes in temperature in North America and Antarctica began around 1200, long before the modern chemicals that are blamed for these changes. What are other explanations?
