[Dr Philip Stott]

All over the City of London there are little memories of the vineyards that grew in the Medieval Warm Period. So this was a wonderfully rich time. And this little church, in a sense, symbolises it, because it comes from a period of great wealth.


Going back in time further still, before the Medieval Warm Period, we find more warm spells, including a very prolonged period during the bronze age known to geologists as the Holocene Maximum, when temperatures were significantly higher than they are now for more than 3 millennia.

[Comment 39: Cut to graph showing the temperature over the past 10,000 years:

Temp – 10,000 years

Like the previous graph (Comment 37, page 29), this is a schematic diagram”, not a plot of real data, from the 1990 IPCC report (Fig 7.1(b), p202, see The dashed line actually represents temperatures at the beginning of the 20th century, and the graph ends before the large warming of the past century, so the Now label is highly misleading.

In terms of the global average, Holocene Maximum temperatures are not known very well, but best estimates suggest they were no warmer than now and only 0.5 °C warmer than in the mid-20th century, although there are considerable uncertainties (see Wikipedia: Thus the programme misleads by asserting facts where there is uncertainty, and where the best guess would be contrary to the programmes assertion. Also, by showing the above schematic, which was produced in 1990, and was not based on real data, and ignoring all of the quantitative research that has been done since then, the programme makers misled the public about the current state of scientific knowledge.

Important context is also missing, in that the warming during the Holocene Maximum can be explained by changes in the Earths orbit (the Milankovitch cycles: see and [NOAA – the National Oceanic and Atmospheric Administration]), which also controlled the ice ages, but which are not relevant to the present warming.
