Although there is still some disagreement in the preliminary results (eg the description of polar ice caps), a lot of things appear to be quite robust as the climate models for instance indicate consistent patterns of surface warming and rainfall trends: the models tend to agree on a stronger warming in the Arctic and stronger precipitation changes in the Topics (see crude examples for the SRES A1b scenarios given in Figures 1 & 2; Note, the degrees of freedom varies with latitude, so that the uncertainty of these estimates are greater near the poles).
Furthermore, the fact is (as shown in Figure 1) that hurricane intensity has increased in recent decades as SST has risen (at least in the North Atlantic for which trends are most reliable) and this prediction is based on fairly fundamental and robust thermodynamic arguments explored by Emanuel and others for decades now.
It is just another illustration that short - term trends like this are not robust, due to natural variability and (as shown here) due to data uncertainty.
In fact, Cane et al (1997) argue that the tendency toward increased SST gradient is precisely what is seen if one uses a robust trend analysis to decrease sensitivity of the trend analysis to outliers such as the very large 1982/1983 El Nino event (this event, and the equally large 1997/1998 El Nino event, greatly influence the estimate of a weakening trend of the Walker circulation in Vecchi et al).
If you do the same for 31 year averages, 32 year averages, 33 year averages, etc., on on through at least 70 year averages, you continue to find an indisputable trend of climate warming — even if you dismiss the land data as flawed because of the use of daily extremes rather than a more robust indication of the daily mean.
«Trend estimates from the SOS [Start of Spring] methods as well as measured and modeled plant phenologystrongly suggest either no or very geographically limited trends towards earlier spring arrival, although we caution that, for an event such as SOS with high interannual variability, a 25 - year SOS record is short for detecting robust trends
Marcott paper Basically the folks at RC have probably made poor ol Marcott respond that the uptick did not matter anyway its not important, significant, robust etc don't rely on it just forget about it please etc but unfortunately for them as Ross MC on Realclimate reply, at CA says «But that is precisely what they do in Figure 3 of their paper, and it is the basis of their claim that «Global temperature, therefore, has risen from near the coldest to the warmest levels of the Holocene within the past century, reversing the long - term cooling trend that began ~ 5000 yr B.P.» Without the uptick in their proxy reconstruction this kind of statement could never have been made.
``... this robust old station, despite the urban effects, shows that there's been no statistically significant warming in Prague since 1800 (and at most 0.5 °C or so in 200 years, and I haven't subtracted any corrections for the intensification of Prague's urban heat island which may be as much as 0.6 °C per century and which would probably revert the 200 - year trend to a significant cooling!)
