Abstract:
Chapter 1 lays the foundations for the Working Group 1 contribution to the IPCC 6th Assessment Report. It describes the context and framing of the report, the methods used across multiple chapters (including uncertainty language, climate model scenarios, regions and more), and recent developments in both scientific approaches and modeling. The chapter also includes a range of scientific assessments, notably on the emergence of the climate signal and the human induced climate influence prior to 1850, and a writeup of the history of natural climate science.
This talk presents key results from Chapter 1, and also serves as a useful introduction to IPCC methodology that will be common to most of the subsequent talks in this JOS series.
In addition, we take a guided tour of the Technical Summary, which is arguably the most readable summary of the report and that also includes cross-chapter results not readily available elsewhere.
What is the Joint Oslo Seminar (JOS):
Atmospheric and climate sciences have a stronghold in Oslo among the four institutions University of Oslo, the Meteorological Institute, CICERO and NILU. This joint seminar invites renowned international experts to contribute to an informal series of lectures, meant to create interaction with the Oslo atmospheric and climate science community on recent highlights and analysis in the field. All seminars will be held on Thursdays (Noon -1pm).
