Earth Temperature Timeline

The popular web comic xkcd presents in a general chart the development of the temperature on earth. The timeline shows how the temperature has changed since 20,000 BCE (Before Common Era) to the present day. The impact of the global warming is obvious. The comic also shows that temperature chances occurred before, as climate change deniers always argue, but the rise of the global warming is happening much faster.
