article_snippet: That document was revised so that the uncertainty involved in trying to model the climate was admitted.
article_snippet: Carbon dioxide levels in the atmosphere have continued to rise, but since 1998 there has been no statistically significant rise in global temperatures at all.
article_snippet: This flies in the face of the confident predictions made by nearly all the climate computer models that the temperature would continue to rise as the temperature did from 1975 to 1998.
article_snippet: More than 60 different explanations have been proposed to explain why this ‘pause’ or ‘hiatus’ has happened, and their sheer number is the clearest evidence that the system that climate scientists are seeking to model is irreducibly complex.
article_snippet: The latest example is the pre-Christmas booklet A Short Guide To Climate Science.
article_snippet: Last year also saw the joint publication with the US National Academy of Sciences (NAS) of Climate Change: Evidence And Causes, and a report called Resilience.
article_snippet: Both the joint report with the NAS and the Short Guide answer 20 questions on temperatures, sea-level rises and ocean acidification.
