1000 years ago there was no global warming, just the normal warming of the earth by the sun. Global warming started when we discovered fossil fuels and started burning them seriously, at the beginning of the Industrial Revolution, about 250 years ago. This burning released age-old carbon dioxide that had been hidden underground for 300 million years.
Carbon dioxide is a greenhouse gas, so extra gas in the atmosphere captures more heat, and this is global warming.
