Subject: section 6.6 material Solar-CO2-aerosols-EMIC figure

Hi,

Robust finding/uncertainty table is fine with me. Good job!

Here the 6.6 material from Bern. It includes an update on solar forcing, an
update on the section on compatibility of the GHG-proxz-forcing records, new
text for the sulfate aerosol figure, new text for the EMIC figure panel e) and
a proposed bullet for the last millennium modeling.

Will send an update of the ice core sulfate figure next week with one additional
curve from Antarctica and an updated figure caption. Otherwise, I think this is
all you need from me for 6.6. Will also hunt recent references for alpine cores
highlighted as missing.

Let me know if I missed something else for the last 2ka section.

- The solar subsection in 6.6.3 requires coordination with chapter 2 – Suggest
to send the text to Dorland and Lean as soon as agreed among us. Note that we
do not have an exec summary bullet on solar forcing – probably captured by chap
2
- should probably also send the para on sulfate aerosols to chap 2 for checking
consistency and cross-referencing
- Have tried to be brief and not to add much, have also suggested to delete
paragraphs.
- note new bullet proposed for exec summary on model results. Would be nice if
sufficient space, but  no strong feeling whether this should be included or
not; may be covered to some extent by the attribution chapter.


KEITH:
	Can you or Tim please provide the number for the smoothing shown in figure 11e:
'The simulated range in decadally-smoothed NH surface temperature is about 60%
KEITH/TIM CAN YOU CHECK/PROVIDE THIS NUMBER WITH YOUR FILTERED DATA larger for
the high amplitude than for the low amplitude case prior to the
industrialization.'

Looking forward to your feedbacks and improvments. We can forward to Oyvind when
finalized.

With best regards,

Fortunat
