E isso é quanto em termos de território?
Gostava de ver o nº de estações vs cobertura geográfica
Se não sabem, ficam a saber que existe um monopólio para o controlo das previsões globais de temperatura por parte do IPCC, pelo que existem inumeras situações em que isso é colocado em causa.
Também não confio na NOAA por issop temos de ver outros como o Hadley Center CRU..

Prof. Pielke salienta
" That is, the simulated value for land heating amount during the 20th century is 41.0x10^22 J while that for observation is only 0.9x10^22 J (during 1955-1998), and the simulated value for ocean heating amount is 100x10^22 J while that for observation is 14.5x10^22 J. Main reason for the discrepancies appears to be the large standard deviation (among models) associated with estimating these values because the conclusion above is based on mean values. Does this mean that the observation values for heating amount can be used to test the models? This may be not the case; two models (i.e., CGCM3.1(T47) and UKMO-HadCM3) give very small values for the land heating as well as for the ocean heating (as a matter of fact, they are zero for these models), and hence, they seem to satisfy the requirement, but at the same time they give very different top of the atmosphere values. These discrepancies may tell us something important; for instance, 1) the models are too coarse to estimate such subtle values, 2) land and ocean were strongly cooled by aerosol and/or clouds which effect was not suitably taken into account in the models, 3) changes in solar constant was overestimated. The last point is, more or less, true. The AR4 models tend to use relatively large solar constant changes to explain the temperature change during the first half of the 20th century. But, the change in the solar constant appears to be too small (0.1%) according to recent theories of solar seismology. Anyway, since the models Shin et al. examined will be considered to reinforce conclusions of coming IPCC AR4, AR4 should contain statements which clarify limitations associated with the models."
Bem mas já estou a fugir ao tema do tópico
Já sentia saudades de uma boa discussão
NOTA: desde o dia 8 de Dezembro apenas tive um dia com chuviscos nem 2 milímetros caio
