Cretaceous was an age which everybody imagines as a global tropical world. In fact and long terms is true, but in this long period it could happen more climates. However there was very quiet period, always we compare with current time; and it has singularities that it goes away to the ideal tropical climate. Cetaceous was hot; but ironically tropics no more than current, while polar seas (there wasn’t any continent in there) was as warmed current areas. Unlike today Cretaceous climate haven’t great differences in relation to latitude, the heat was efficiently transported to the poles by the oceans. Planet hasn’t a significate temperature gradient, so winds was only an anecdote, and it means that more part of land emerge (without continental ice of Antarctica level sea was more of 200 meters higher than today, The great flood) was a desert (read The day after Tomorrow where explain little the importance of distribution of continents and current climate).
This presentation tray to explain how difficult is stablished the degree hot of any time period. Nowhere have the same orographic shape every time, and climates evolve with it; Cretaceous and today aren’t comparable. To say “the hottest year than ever” is a phrase surely false. All Cretaceous if we could apply the same parameters of today was hotter than any of the 26 million years. Unfortunately we can’t apply; temperatures or localization of real sites are only estimates. Therefore we can compare 2014 with the last 100 years, and the answer is yes; 2014 is the hottest year from we have real meteorological data.
Some people can’t believe this. 2014 began with polar vortex, tree chips caught in the Antarctic Ice, and Climate Deniers blaming about the imminent arrived of Ice Age. Even then global main temperature was higher than other similar north winters. Today I write near of Mediterranean Northern Coast, but temperature in street is -6 Celsius degree in a town at 300 meters above sea level, hot compared with current temperatures in northern Europe but very cold compared to normal for the time. But satellite data confirms the opposite of our perception seems. It may seem a contradiction but it has a very easy reason other sites of North Hemisphere are temperatures higher than normal for the time; in fact just one week weather in my town was as beginning of fall, and the last month (November) weather was as summer.
The supposed Global Warming Hiatus or Pause is only an invention of Climate Skeptics, who’s taken partial data for corroborate their hypothesis. In the beginning of 2013 (winter is the better time to publish denier postulates) some corrections of the IPCC model and the Britain Met Office Scandal about some e-mails that affirms falsifying data, were the trigger for the campaign to the Global Warming Hoax. Two item are true; but the main data before, while and after scandal were contrasted, and models are always correcting. All model parameters adjustment that corrects when compared with reality; in other hand more boundaries are adding after when it see their needed. For example melting ice are beginning to be relevant in the moderation of temperatures; when main temperature are low melting was insignificant, but current temperatures melting more ice, melting ice waste energy without change of temperature; the current models proves to including the melting ice (read Really are temperatures stopping its rice?). However even correction all the models foresee a rise in temperature.
Data is concluding: Earth is warming day by day. There are satellites that scrutinize temperatures around the globe. There are also controlling the thermal forcing, is to say the balance between the energy that enters and leaves. Climate is in the eye, because every year increases the amount of economic losses that causes. And only the other economic interest, the interest of fossil energies which doesn’t want to lose their business.
