Yet they turn around and find absolute certainty that they've found a long - term
trend in solar irradiance, where our direct measurements span only a couple of
decades, barely more than two
full 11 - year cycles, and we're up against serious challenges on inter-satellite calibration.
The northern - hemisphere anomaly: — is larger in absolute terms; — is much larger in relative terms; — has had a very clear
trend for two
full decades; and — this
trend has clearly accelerated in the last five years.

If only half of the modern decadal warming is due to human influences, then it is also likely that the human - caused linear
trend would represent a warming rate of only +0.89 °C, half the modern 3 -
decade full - linear
trend rate of 1.78 °C / century.
To point out just a couple of things: — oceans warming slower (or cooling slower) than lands on long - time
trends is absolutely normal, because water is more difficult both to warm or to cool (I mean, we require both a bigger heat flow and more time); at the contrary, I see as a non-sense theory (made by some serrist, but don't know who) that oceans are storing up heat, and that suddenly they will release such heat as a positive feedback: or the water warms than no heat can be considered ad «stored» (we have no phase change inside oceans, so no latent heat) or oceans begin to release heat but in the same time they have to cool (because they are losing heat); so, I don't feel strange that in last years land temperatures for some series (NCDC and GISS) can be heating up while oceans are slightly cooling, but I feel strange that they are heating up so much to reverse global
trend from slightly negative / stable to slightly positive; but, in the end, all this is not an evidence that lands» warming is led by UHI (but, this effect, I would not exclude it from having a small part in temperature
trends for some regional area, but just small); both because, as writtend, it is normal to have waters warming slower than lands, and because lands» temperatures are often measured in a not so precise way (despite they continue to give us a global uncertainity in TT values which is barely the instrumental's one)-- but, to point out, HadCRU and MSU of last years (I mean always 2002 - 2006) follow much better waters» temperatures
trend; — metropolis and larger cities temperature
trends actually show an increase in UHI effect, but I think the sites are few, and the covered area is very small worldwide, so the global effect is very poor (but it still can be sensible for regional effects); but I would not run out a small warming
trend for airport measurements due mainly to three things: increasing jet planes traffic, enlarging airports (then more buildings and more asphalt — if you follow motor sports, or simply live in a town / city, you will know how easy they get very warmer than air during day, and how much it can slow night - time cooling) and overall having airports nearer to cities (if not becoming an area inside the city after some
decade of hurban growth, e.g. Milan - Linate); — I found no point about UHI in towns and villages; you will tell me they are not large cities; but, in comparison with 20-40-60 years ago when they were «countryside», many small towns and villages have become part of larger hurban areas (at least in Europe and Asia) so examining just larger cities would not be enough in my opinion to get a
full view of UHI effect (still remembering that it has a small global effect: we can say many matters are due to UHI instead of GW, maybe even that a small part of measured GW is due to UHI, and that GW measurements are not so precise to make us able to make good analisyses and predictions, but not that GW is due to UHI).
Note that for each data set, the
full - sample (about 30 years)
trend is within the confidence interval of the 10 - year
trend — so there's no evidence, from any of the data sets, that the
trend over the last
decade is different from the modern global warming
trend.
Since we already have data for the
full year of 2011, I have calculated the warming
trend required for the next 9 years to reach 0.2 deg C over the entire 20 - year period (and that is a linear warming rate of around 0.556 degC per
decade, or a linear warming of 0.5 degC over the 9 - year period that is still left.
In fact, in the most recent few
decades, the rural sites have become slightly warmer than the
full data set, and show a
trend of -0.19 + / - 0.19 °C per century over the 1950 - 2010 time period, roughly consistent with the
trends reported in the first method.
The

Several analyses of ring width and ring density chronologies, with otherwise well - established sensitivity to temperature, have shown that they do not emulate the general warming
trend evident in instrumental temperature records over recent
decades, although they do track the warming that occurred during the early part of the 20th century and they continue to maintain a good correlation with observed temperatures over the
full instrumental period at the interannual time scale (Briffa et al., 2004; D'Arrigo, 2006).
