hi, okay, first, you spelled 'medieval' wrong. second, you're using the tag 'climate change' incorrectly. climate change is not strictly man-caused. climate change is the shifting of multiple factors, such as precipitation, weather patterns, sea levels, etc., not just the general temperature of the planet. climate change is normal. it is natural in certain circumstances. but the current climate change we're experiencing isn't like the normal shifts seen over *long periods of time* similar to the past. it is exceeding what could be explained by natural causes. also, climate change isn't interchangeable with global warming? i think that's what you were going for. and your graph is just... incorrect.
