I was given permission by Euan Mearns (Javier) to show his work on the reconstruction of the climate of the entire Holocene.  You can read his report here,

Fig.9 is a summary of all known results that deal with the climate reconstruction of the past.

Figure 9. Holocene climate reconstruction. Major palinological subdivisions of the Holocene (names on top) match a 2500 regular spacing (grey arches on top). The global temperature reconstruction (black curve; Marcott et al., 2013 by the differencing method with proxy published dates) has been rescaled in temperature anomaly to match biological and glaciological evidence and instrumentation temperature measurements, resulting in the Holocene Climate Optimum being about 1.2°K warmer than the Little Ice Age. The general temperature trend of the Holocene follows the Earth’s axis obliquity (purple), and significant downside deviations generally match the lows of the ~ 2500-year Bray cycle of solar activity (grey boxes labelled B-1 to B-5). Significant negative climate deviations manifested also by global glacier advances (blue bars; Mayewski et al., 2004) and strong increases in iceberg detrital discharges (red curve, inverted; Bond et al., 2001) generally agree well with the lows in the ~ 2500-year Bray cycle and ~ 1000-year Eddy cycle (not shown) of solar activity.

[Observe that the beginning of the Holocene is marked by recovery time after the Younger Dryas cooling period. Many scientists like myself believe that the cause of this cooling period was due a great catastrophe that is also related to the Big Flood of Noah]

Note that the temperature of the planet is set by the obliquity (tilt) of its axis, not so much by solar variability, and Earth’s obliquity is decreasing every day at the fastest rate in forty thousand years (figure 9). Only once in the last million years have temperatures failed to fall with falling obliquity, but when this happened (during MIS 11, 400 kyr ago), 65°N summer insolation was very high, while now it is very low.

The rebound effect of the post-LIA (Little Ice Age) natural warming together with any anthropogenic warming contribution has probably taken us above the temperature that corresponds to the present inclination of the axial tilt, since by a variety of biological and physical methods our present state appears to be similar, at least in the northern hemisphere, to the conditions around the Mid-Holocene transition ~ 5000 years ago. It is possible therefore that over the next 1-2 centuries global temperatures might naturally descend by 0.2-0.4°K to reach our obliquity target, regardless of solar activity.

I would expect significant cooling and climate change from reduced solar activity around 2600 AD when the next low in the ~ 1000-year Eddy cycle is expected.

 [Looking at the temperature trend on the graph]

We might face a solar future similar to what the Romans enjoyed between 150 BC and 350 AD. [This is in fact ] A very positive development if true.

In terms of climate, the post-LIA natural warming should end soon if it hasn’t ended already, because these recovery periods from the lows in the ~ 2500-year Bray cycle rarely last for more than 400 years. As solar centennial activity cannot increase further, we are probably moving to an end to natural warming.

Glacial inception, the onset of the next glacial period, could take place around 4000 AD when the next low in the ~ 2500-year Bray cycle acting on a much lower obliquity should set the conditions for the growth of the ice sheets.

This means that the graph is up to date to present day. The reader sees with me that the image of Fig. 9 is something very different from that published by the IPCC. It is not warmer now than it has been in earlier times. God is good].
