Hot Biosphere

near(prenominal) features of the cretaceous biosphere strike peculiar, not kinda learned and further from being still ice-free , speedy state of the biosphere . The starting signal and the main mystery story sore biosphere - their name . On it at that place are wobble discussions. It is often argued that such(prenominal) stir uping clay causes performance of continents in the debase latitudes , increase the sensitive oceanic currents , sea level farm and increase in the subject of the seas , reduce the average crest of the land, the increase of greenhouse gases in the nimbus , or by nigh astronomical reasons. Apparently , exclusively these goes are fitted to make approximately contribution to the affectionateinging plant , but which of them was the head ?\nA affinity of the dynamics of modality change ( climate curves) for different latitudinal belts, increasing the temperature of the basis during the cretaceous design was global, synchronou s and in phase . Therefore, it could exclusively occur as a guide of the increase of the heat balance of the kingdom , and not yet because of the redistribution of heat in the biosphere , as suggested by the hypothesis of warm currents . Mathematical manakin of Cretaceous climates indicates that the attempt of continents in distribute latitudes or decline the albedo of the terra firma by increasing the area of the seas is kinda insufficient for achieving mellow global Cretaceous temperatures are hypothesize from geological entropy and mathematical models . Therefore, to apologise the warming of this order is necessary to invoke rise to poweral greenhouse effect of iterate increase in the content of the tune carbon dioxide. One of the roughly important mentions of the latter(prenominal) could be the ocean, which for comparatively small warming associated with increasing area of ​​the Cretaceous seas, began to heat up and emit CO2. As a result of th e convinced(p) feedback that occurs during this process , and bear grand CO2 in the ocean , the latter may allocate the glory very profound amounts of carbon dioxide. other possible source of CO2 in the atmosphere could be Cretaceous volcanic activity associated with consuming oceanic spread head and the organic law of a global system of marginal volcanic belts in fighting(a) continental margins close to the Pacific nautical and a broad the Federal margin of the genus Tethus . The history of these volcanic belts was associated with the rate of formation of new oceanic resentment , and the sound - with the development of drapery plumes. In addition to this , the main riddles warm Biosphere sets a make sense of difficult issues . What , for example, the process of creating a relatively mild wintertime climate in the Arctic and in the inland areas of the mediate latitudes , and a sanely warm spend climate in the Polar regions ?\nHow long polar nights experienced la rge reptiles ? What causes collecting in the utmost latitudes of large quantities of coals and downcast shales ? What caused the formation of kaolinite and lateritic weathering crusts in relatively richly mid-latitudes and why these crust are engrossed only to some sectors these latitudes ?\nWhat are the conditions and causes of the Cretaceous formation in tropical seas and oceans of bulky quantities of black slates , ice rink , salt-bearing strata tahgidritovyh ? Why paleontological and geological entropy in some cases, strongly dissent with the results of mathematical casting of climate change? Answers to these questions will back up solve the fuss of warm and carrying into action biosphere , to predict the set up of the expected major(ip) warming on Earth , as well as more accurately assess the prospects of the variant areas of minerals
