Global Climate Change

Medieval Global Temperature Optimum
The Medieval Global Temperature Optimum occurred during the European Middle Ages from approximately 950-1250 AD. Basically, it was a period of warm climate that is believed to have been related to other climate events occurring around the world at that time. It primarily affected the North Atlantic Region. However, there were also documented climate events in China and California.

Little Ice Age
The Little Ice Age began after the Medieval Temperature Optimum from approximately 1350-1850. However, climatologists do not all agree on its specific start and end dates. Contrary to the period before it, the Little Ice Age was a period of global cooling. It certainly brought colder winters to Europe and America. Furthermore, there is evidence to suggest that it also affected most other parts of the world including New Zealand, Australia, Patagonia, and even Africa. This had severe implications for the way of life  in those areas. For example,  farmers could not manage their crops due to the temperature drop. This demonstrates the profound effects that climate change can have on our way of life.
