Paul Levy (M Star February 18) is erecting a straw man argument when he denounces Jean Johnson (M Star February 17) for claiming "a systematic attempt on the part of the climatic research unit to manipulate" in her response to Michael Meacher's playing down of the collapse of the catastrophic warming evidence.
She did not say that the disappearance of data from Chinese sites and the Climate Research Unit's reliance on measurements which have been urbanised or moved or both was deliberate manipulation.
She merely said that it had happened - though untrusting folk like myself may find it improbable that all the errors uncovered here and elsewhere should accidentally be angled towards scaring us.
The urban heat island effect is well proven and indeed it is obvious that cities, using electricity, cars, fire etc will give off more heat than countryside.
With the very rapid industrialisation of China it is equally obvious that this is an even greater effect there. Those claiming to see catastrophic CO2-caused warming by using uncorrected or not fully corrected measurements from urban areas are clearly doing very bad science, if it can be called science at all.
Unfortunately time after time in figures from country after country this is what we see being done.
When Stephen McIntyre found a programming error of this sort in the US figures, he proved that the actual warmest year in the non-urban US was 1933, not 1998.
The alarmists explained that catastrophic warming was still proven by 1998 being the warmest year outside US boundaries, but there must be doubt about that.
If so not only do we not have any catastrophic warming but we have had cooling, not only over the last decade but since 1933.
Never mind. I am sure there will be another eco-catastrophe story along shortly.
