IPCC AR5 WG1 Report: Course Information
Motivating questions:
What are the key findings?
On what evidence are they based?
Where are there critical knowledge gaps?
FULL FINAL REPORT WILL POST JAN 30.
Final SPM is posted: http://www.ipcc.ch/report/ar5/wg1/

Course participation
a) Sign up for presentation – think about it so we can
start assigning by end of class
a) All are welcome to present, students are given first
priority in choosing chapters.
Schedule with names will be on course website
b) credit options:
1 point (discussion only)
2 points (discussion + presentation)
3 points (discussion + presentation + paper)
We welcome involvement from the full LDEO community.
Feel free to join us whenever possible.
Class Schedule: 14 chapters in 13 weeks

Guidance on presentations and final paper
(additional details posted on course website)
Presentations: focus on the figures and the stories they tell.
• Plan on presenting ~15-20 figures per class
2 options for final Papers (8 page max):
Option #1: Choose a “hot” research area topic and critically assess the
new findings since the IPCC AR5 WG1 publication freeze date (March
15, 2013). How should the 2013 report be updated in light of these
new findings?
Option #2: Identify a critical knowledge gap, either explicitly discussed in
the report or one that you feel should have been. Write a paper or a
research proposal describing the work needed to fill this gap.
The rest of today

Report
IPCC (2007):
• Warming in the climate system is unequivocal, as is now
evident from observations ....
• Most of the observed increase in global averaged temperature
... is very likely due to ... increase in GHG concentrations.
• Continued GHG emissions ... would induce many changes ...
that would very likely be larger than those observed ...

Course Goals
 Learn the scientific evidence behind headline -and otherstatements in AR5.
What are the key findings?
On what evidence are they based?
-- models, observations, theory
-- strength of evidence
Where are there critical knowledge gaps?
