That‘s undisputed. But the used reference timespan isn‘t the „norm“ and it‘s not certain that we haven‘t had similar short peaks in the past 22000 years - which is what the xkcd illustration at least strongly suggests.
- bjourne 8y agoThat objection is addressed at the 16000 BCE mark. We have had short peaks before such as the Krakatoa eruption that reduced world average temperatures by 1.2 degrees for five years. What we're now experiencing is a continuous increase that has already raised temperatures by one degree over 100 years. I think it is very unlikely that anything similar has happened before.
