It looks likely that the rapid warming of the Arctic has broken the thermometer temperature record in two different ways - firstly by violating the assumption that unobserved regions of the planet warm at a broadly similar rate to observed regions, and secondly by violating the assumption that neighbouring regions of the planet's surface warm at a similar rate.

http://news.bbc.co.uk/1/hi/sci/tech/8511670.stm So, in answer to the question, the warming rates for all 4 periods are similar and not statistically significantly different from each other.

I linked to the Phil Jones article, that said the late 20th century, warming was not statistically different to early similar periods of warming, thus we can discard the unprecedented claim for late 2oth century rates of warming.

The DECC used to show the actual temp data CET data set graph (still only 150 years of it) on the DECC website, but following Phil Jones stating in that BBC interview, 3 similar warming periods, and rates of warming in the last 150 years and that you could clearly see this on the graph, the pronouncement by the DECC that this graph showed «unprecedented» man made global warming, seemed ridiculous.

Both of these are emitted at high rates similar to Earth, and this planet warms.

Looks like a lot of variability in climate in this period, quite pronouced warming periods and rates of warming (and cooling) throughout the centuries, similar to the late 2oth century, as Phil Jone's agreed in that BBC interview (link above)

Comparing the global temperature at the time of the most recent three La Ninas (1999 - 2000, 2008, and 2011 - 2012), it is apparent that global temperature has continued to rise between recent years of comparable tropical temperature, indeed, at a rate of warming similar to that of the previous three decades.

Yet its own temperature dataset proves past natural global warming rates of earlier periods are similar and as powerful.

Thus, pathways with lower rates of emission in 2050 are likely to result in a similar amount of peak warming, while higher rates of emission in 2050 can lead to varying levels of peak warming, as seen in figure 2d.

Our devotee will also pass by the curious additional facts that a period of similar warming occurred between 1918 and 1940, well prior to the greatest phase of world industrialisation, and that cooling occurred between 1940 and 1965, at precisely the time that human emissions were increasing at their greatest rate.

The only «fact» we have here is that it appears to have stopped around the end of 2000, and has cooled slightly since then (at a cooling rate similar to the warming rate experienced from 1850 to 2000, or around — 0.06 °C per decade).

Then further warming at the rate of 0.16 deg C per decade will resume until another peak by 2060, similar to the peaks in the 1880s, 1940s, & 2000s.

The point to be made regarding that paper is similar to the one I made above: there is evidence that internal variability (to the extent it can be equated with the AMO) has affected the rate at which anthropogenic forcing has warmed the surface, but most of the warming must have been forced, with the observed positive ocean heat uptake data excluding more than a very minor role for internal variability in the warming itself with very high confidence.
