Global Warming

In discussions about the reasons of global changes of a climate new turn is noted. An essence of a problem: whether really plants allocate in an atmosphere metane in quantities which are capable to aggravate anthropogenous warming of a climate?

In opinion of Franc Kepplera (Frank Keppler) from Planck’s institute Maksa (Germany) and Thomas Rokmanna (Thomas Rockmann) from the Utrecht institute of sea and atmospheric researches (Holland), plants really bring the essential contribution to the further development. However botanik Volume Djuk (Tom Dueck) and its colleagues from Plant Research International in Vageningene (Holland) have carried out researches with use of more exact analytical methods and have not found proofs in favour of this position, informs Scientific American.

As have shown results of this work, plants allocate very insignificant quantity of metane in an atmosphere. Thus, F.Kepplera and T.Rekmanna’s hypothesis has not received experimental acknowledgement and it, undoubtedly, will lead to a new coil of discussions about motive forces of modern global changes of a climate.

In the center of this discussion there was a question on a methodical correctness of the applied experimental methods. As considers F.Keppler, use in T.Djuka’s work of an isotope of carbon Ñ14 atoms of carbon and tracking of ways of its migration in system “plant-atmosphere” can lead to unpredictable changes of a metabolism of the plants.

On the other hand, T.Djuk specifies, that radioactive metan carbon in researches on physiology of plants many years and as it has been repeatedly shown are applied, does not render influence on normal ability to live. Besides in opinion of the scientist, group Kepplera grew up skilled plants in inadequate conditions - at the limited exchange of air with Wednesday and at influence of some stress-factors. As a result of a plant could “decay” simply in conditions of experience, allocating thus in an environment significant amounts of metane.

Thus, as consider T.Djuk and its colleagues, F.Kepplera and T.Rekmanna’s conclusions are incorrect, as are under construction on results of methodically incorrect experiments. However it is not clear (on what specifies Keppler), than it is possible to explain for example that fact, that frequently in air above tropical woods of the maintenance of metane considerably above an average. So, discussion about the contribution of plants to a hotbed effect proceeds. And before its logic end the valid role of a vegetative cover in global changes of a climate remains a riddle.

Up to 40 % of the population of the Earth will feel on itself consequences of melting of snows, glaciers and a permafrost. Such conclusion contains in the new report of the program of the United Nations on an environment, dated to World day of preservation of the environment marked on June, 5th.

Authors of the report which ” the Global sight ” refers to, warn, that melting of snows and ices can cause flooding of coastal areas and islands, flooding and landslips, especially in mountain areas.

In Siberia increase of temperatures and melting of a permafrost will lead to liberation of huge volumes of metane which, getting in an atmosphere, will aggravate a hotbed effect. By estimation of scientists, scales of such issues will be five times more, than was considered earlier, the news service of the United Nations informs on Tuesday, on June, 5th.

Under forecasts of experts of the United Nations, reduction of snow and ice covers also leads to that the ground and polar oceans absorb more solar heat, and in turn, can accelerate rates change of a climate.

The member of the program of the United Nations on environment Ahim SHtajner has told, that the purpose of the report - to cause feeling of doom, and to push to actions. ” We do not get tired to repeat, that so far as activity of people in the big degree has led to global warming, they can and should change the developed situation “, - has declared SHtajner in interview which is quoted by news service of the United Nations.
