Climate Change Data Cartoon
The below cartoon-ish rendering of global temperature data illustrates just how extraordinary the observed temperature rise has been since the age of industrialization. The timeline is divided in 6 parts, further below you see the full timeline - lot's of scrolling required ;)
Essentially, the highest rate of temperature change before 1850 was roughly 1K/500y.
After the industrialization, global average temperature has increased by roughly 1K in just 50 years!
