<5111> Pollack:

But it will be very difficult to make the MWP go away in Greenland.

<5039> Rahmstorf:

You chose to depict the one based on C14 solar data, which kind of stands out
in Medieval times. It would be much nicer to show the version driven by Be10
solar forcing

<5096> Cook:

A growing body of evidence clearly shows [2008] that hydroclimatic variability
during the putative MWP (more appropriately and inclusively called the
“Medieval Climate Anomaly” or MCA period) was more regionally extreme (mainly
in terms of the frequency and duration of megadroughts) than anything we have
seen in the 20th century, except perhaps for the Sahel. So in certain ways the
MCA period may have been more climatically extreme than in modern times.

<0310> Warren:

The results for 400 ppm stabilization look odd in many cases [...] As it stands
we’ll have to delete the results from the paper if it is to be published.

<1682> Wils:

[2007] What if climate change appears to be just mainly a multidecadal natural
fluctuation? They’ll kill us probably [...]

<2267> Wilson:

Although I agree that GHGs are important in the 19th/20th century (especially
since the 1970s), if the weighting of solar forcing was stronger in the models,
surely this would diminish the significance of GHGs.
[...] it seems to me that by weighting the solar irradiance more strongly in the
models, then much of the 19th to mid 20th century warming can be explained from
the sun alone.

<5289> Hoskins:

If the tropical near surface specific humidity over tropical land has not gone
up (Fig 5) presumably that could explain why the expected amplification of the
warming in the tropics with height has not really been detected.

<5315> Jenkins/MetO:

would you agree that there is no convincing evidence for kilimanjaro glacier
melt being due to recent warming (let alone man-made warming)?
