Opis:
The European Union accepted the ambitious project of decarbonization of economy. The main goal is a 90 percent reduction of CO2 emissions in comparison with 1990 emissions, which will result in the so-called climatic neutrality. In this project, several goals are obvious and not subject to discussion. But there are several conditions, previously not discussed, which could bring this program into question. This paper concentrates on the problem of methane hydrates. Methane hydrate reservoirs mainly occupied the bottom of the oceans and the volume of methane in these reservoirs is greater than the volume of hydrocarbons in all other reservoirs. Currently, three different theories about hydrates coexist: the methane hydrates is a huge energy source and a new golden age is coming; the methane hydrates are a time bomb – global warming causes dissociation of these reservoirs and a global warming catastrophe; the ocean is warming so slowly that we have several hundreds of years until eventual dissociation of methane hydrate reservoirs. Essentially, the third approach could be applied if it was not for Gulf Stream. This ocean current brings a great amount of heat to the Arctic region. It is an additional factor of global warming. Therefore, three effects are possible for the ocean areas through which Gulf Stream flows. There is methane hydrates reservoirs dissociation causing methane migration into the atmosphere, sediment landslides on shelf slopes and the associated potential tsunami, and change of thermobaric conditions connected with vanished ice sheet. The free methane cumulated under methane hydrate deposits will also migrate into the atmosphere. Appropriate models for simulation of all these possibilities do exist, however we do not have sufficient data. Thus, creation of a reliable data base is the first goal. Maps of extents of hydrate reservoirs, depth of reservoirs and results of several years of examinations of surface and bottom temperatures must be gathered in this database. This will allow us to investigate all possible scenarios.
