While there remain disparities among different tropospheric temperature trends estimated from satellite Microwave Sounding Unit (MSU and advanced MSU) measurements since 1979, and all likely still contain residual errors, estimates have been substantially improved (and data set differences reduced) through adjustments for issues of changing satellites, orbit decay and drift in local crossing time (i.e., diurnal cycle effects).

To remove this difference in magnitude and focus instead on the patterns of change, the authors scaled the vertical profiles of ocean temperature (area - weighted with respect to each vertical ocean layer) with the global surface air temperature trend of each period.

Thus it is very important to know what the real impact of historical solar changes is, as 0.1 K in the past, results in climate sensitivity for anthropogenic at the high end, while 0.9 K results in a very low effect of anthropogenic, if the instrumental temperature trend of the last 1.5 century is used as reference.

The warming trends in looking at numerous 100 year temperature plots from northern and high elevation climate stations... i.e. warming trends in annual mean and minimum temperature averages, winter monthly means and minimums and especially winter minimum temperatures and dewpoints... indicate climate warming that is being driven by the accumulation of greenhouse gases in the atmosphere — no visible effects from other things like changes in solar radiation or the levels of cosmic rays.

Human induced trend has two components, namely (a) greenhouse effect [this includes global and local / regional component] and (b) non-greenhouse effect [local / regional component]-- according to IPCC (a) is more than half of global average temperature anomaly wherein it also includes component of volcanic activities, etc that comes under greenhouse effect; and (b) contribution is less than half — ecological changes component but this is biased positive side by urban - heat - island effect component as the met network are concentrated in urban areas and rural - cold - island effect is biased negative side as the met stations are sparsely distributed though rural area is more than double to urban area.

However, there are various other plausible explanations, for example: — changes in US temperatures since the 1930s / 1940s show regional variation within the overall warming trend at those latitudes; — actually I'm struggling to think of any others, apart from inaccuracies in the US temperature record but these have tended to point the other way.
