Much climate change theory is contradicted by other science.
Robin Trow is scathing in his criticism of climate change sceptics but I am proud to be one (Letters, PE July).
Although I do not dismiss all elements of the man-made climate change theory, I believe there is sufficient uncertainty that we should not be "betting the farm" on it in the way that we appear to be doing.
Too many of the things the man-made climate change theory tells me are true are contradicted by other science. The greatest of these is the enormous error bars that appear on every version of the hockey stick graph that I have ever seen. Going back further than a couple of hundred years, the experimental error on this data is nearly as great as the recent C[O.sub.2] increases that are supposed to be giving us so much concern.
We are told that the melting Arctic ice cap is causing sea levels to rise. This ice cap is denser than the sea on which it floats and so on melting would cause sea levels to fall.
The theory also suggests that the acceleration in the loss of Arctic ice proves that the temperature is increasing. It no more proves this than grains of sugar dissolving faster than a sugar lump prove that one cup of tea is hotter than another.
The most recent news from the Antarctic is that sea ice is increasing; the man-made climate change rationalisation of this is that the ice under the cap is melting, and refreezing when it hits the ocean. Even if this were credulous, it pokes a hole in R T Martin's otherwise interesting observations about latent heat in the same issue of PE.
Since the global temperature has stabilised and the phrase global warming has been dropped in favour of climate change, we are told that only this theory can explain the more extreme weather we are recording. This is also not true. We have increased our monitoring of weather metrics dramatically to the point where we measure them everywhere, to several decimal places. So not only should it be unsurprising to find more extremes, it is inevitable that we will.
