Since the Euro 3 regulations in 2000, performance has been measured using the New European Driving Cycle test (NEDC; also known as MVEG - B), with a «cold start» procedure that eliminates the use of a 40 - second engine warm - up period found in the ECE+EUDC test cycle (also known as MVEG - A).

What is shockingly ill - advised to me is that the Pielke and McIntyre projections both required, in order to fit with their hoped for story line, that the adjustments not only affect the period from 1945 to 1960, but also extend beyond that into the late 90s, in order to level the more recent temperature increases so as to both make the rate appear less dramatic and the amount of recent, CO2 forced warming less of a concern.

It also shows, consistently, that nobody is trying to «get rid of the medieval warm period» or «flatten out the little ice age» since those are features of all reconstructions of the last 1000 to 2000 years.

If there is a hard data gap for this period, then Cato has done a positive service (for once) by pointing out that Warming Island might also have been disconnected from the land in this period... thus deflating the landmark's «poster child» status as an indication of unusual climate change.

Given the total irrelevance of volcanic aerosols during the period in question, the only very modest effect of fossil fuel emissions and the many inconsistencies governing the data pertaining to solar irradiance, it seems clear that climate science has no meaningful explanation for the considerable warming trend we see in the earlier part of the 20th century — and if that's the case, then there is no reason to assume that the warming we see in the latter part of that century could not also be due to either some as yet unknown natural force, or perhaps simply random drift.

Actually, there is some interesting work being done by Matt Huber of Purdue, following up on some earlier ideas of Emanuel's, suggesting that the role of TCs in transporting heat from equator towards the poles may be more significant than previously thought — it also allows for some interesting, though admittedly somewhat exotic, mechanisms for explaining the «cool tropics paradox» and «equable climate problem» of the early Paleogene and Cretaceous periods, i.e. the problem of how to make the higher latitudes warm without warming the tropics much, something that appears to have happened during some past warm epochs in Earth's history.

Whether the oceans net absorb or release CO2 during a period of warming depends not just on the warming but also on changes in the partial pressure of CO2 in the atmosphere above the oceans.

They also fail to appreciate that because solar radiation was at a historic high during the period in question it likely follows that there was a net solar warming of the oceans throughout the period even though the rate of solar radiation was on average stable during that period.

The article also quoted Dr. Patrick Michaels, director of the Cato Institute's Center for the Study of Science, who said: «October 1st marks the 17th year of no global warming significantly different than zero and those 17 years correspond to the largest period of CO2 emissions by far over any other 17 - year period in history.»

Two years before that, the U.N. also warned that global warming was about to usher in a huge period of population disruption, leading to a global refuge crisis.

The major focus was the depiction of the Medieval Warm Period (MWP) from approximately 950 to 1350 AD, but the cold spell from 1350 to 1850 known as the Little Ice Age (LIA) was also a concern.

In particular, as even a brief perusal of Luning and Varenholt's sources shows, the warm periods shown in their sources are not aligned over a set period and include colder spells within their warm periods which may also not align.

This rate (0.28 degC per century) is very different to the rates referred to by Phil Jones for the warming periods detailed in my above comment, so the slow down is very apparent when the last 20 years is compared to the rate of the 1860 to 1880 warming episode which was slightly greater than the 1920 to 1940 warming episode, and also slightly greater than the late 20th century warming episode
