Introduction:
This chapter assesses the evidence-basis for large-scale past changes in selected components of the climate system. The current chapter focuses upon observed changes in climate system drivers and changes in key selected large-scale indicators of climate change and in important modes of variability, which allow for an assessment of changes in the global climate system in an integrated manner. It does not consider changes in observed extremes, which are assessed in Chapter 11.
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.
