I don't attribute ALL the recent observed warming to UHI effects and exagerrated adjustments.
We saw the mid latitude jets move poleward for 25 years or so and that is an indicator that a warming trend was in progress. Warming proponents asserted as much and attributed the cause to more CO2 in the air.
However against the expectations of warming proponents the jets started moving back equatorward 10 to 15 years ago and now the effects are becoming obvious.
The accumulation of warm years recently is simply because we are approaching, or are at, or are leaving a 500 year upward curve from the depths of the Little Ice Age.
The upward progression is not smooth and the next downward progression won't be either. Indeed we may yet have a couple more warming cycles seperated by cooling cycles before we match the peak of the Mediaeval Warm Period and start a proper downward trend again.
Theres no change in the laws of physics required to follow my 'model'. That model complies with the established laws of physics but uses logic to deduce from those laws and from real world observations the correct sequence of events. I then go on to point out to readers a set of propositions that must be true to achieve a match between the laws of physics and real world events.
If alternative propositions can be formulated to achieve a similar match then so be it. However the idea of CO2 as a significant climate forcing agent is obviously not one such because the match between theory and reality becomes daily weaker.
