Welcome to the Anthropocene: Extending the New Climate Data
March 18, 2013
I don’t read or speak Dutch, but a Dutch blogger has extended the graph forward a century, and backward to the last glacial period. I expect this will be translated into english, and will provide more info when I see it. If anyone wants to try google translate to make sense of it, by all means.
Powerful image of the anthropocene, though.
The Anthropocene is an informal geologic chronological term that serves to mark the evidence and extent of human activities that have had a significant global impact on the Earth‘s ecosystems. The term was coined recently by ecologist Eugene F. Stoermer, but has been widely popularized by the Nobel Prize-winning atmospheric chemist, Paul Crutzen, who regards the influence of human behavior on the Earth’s atmosphere in recent centuries as so significant as to constitute a new geological epoch for its lithosphere. To date, the term has not been adopted as part of the official nomenclature of the geological field of study.

Starting in March 2013 appeared in Science an article about a temperature reconstruction for the last 11,000 years . The lead author is Shaun Marcott from Oregon State University and the second author Jeremy Shakun, which we know from the previous year published and interesting research on the relationship between CO2 and temperature during and after the end of the last ice age. Temperature reconstruction of Marcott is the first full period of the Holocene covers. Obviously not perfect and the coming years will probably details on what changed. A normal part of the scientific process.
The temperature reconstruction ends mid century, therefore, in the graphs of their study the rapid temperature rise after 1850 is clearly visible. And what do you find? Again something that looks like a hockey stick as the graph in Mann et al 2008 .
