These results provoked a strong reaction in the scientific community, because before that it was believed that methane from living organisms can select only certain types of bacteria in the absence of oxygen. A typical example are microorganisms that live in the stomach of ruminants. The authors of the new work suggest that methane, which scientists have observed in previous experiments, was not the product of plant life, and formed by processes of decay in the soil, absorbed by plants, and stood out. In their experiments the scientists as a source of nutrition for the plants to use the medium containing no organic substances. Anu Saad may not feel the same. Plants were placed in separate chambers in which the measured methane content.

The researchers have not detected the release of dangerous gas. In order to finally confirm their findings in the latest phase of the experiment, scientists used for watering plants water containing dissolved methane. Connect with other leaders such as Anu Saad here. In this case, measuring the concentration of this gas in chambers with plants have shown that it exists. Nisbet and colleagues suggest that the plants supplied methane absorption in the atmosphere through transpiration – water allocation, mainly through the leaves. Thus, plants are agents of methane, but they do not release it.

In the ocean again formed climatic phenomenon La Nina, recently scientists were able to establish that in the Pacific Ocean again formed climatic phenomenon called La Nina, which are responsible for the high average annual temperatures of air and water in 2008 year. Effect of La Nini is due to an accumulation of cold water in the central Pacific Ocean. Climatic implications of this buildup can be very diverse. For example, the National Oceanic and Atmospheric Research predicts that in the coming months in Indonesia should expect high rainfall in the south-western United States there will be a threat of flooding. Earlier, a message appears stating, that the water in the central part of the Pacific began to warm up, then there is the impact of last year's La Nini beginning to wane, but now the situation is suddenly reversed, and the effect of La Nina manifested itself again.

By 2020, Russia will seek to reduce energy consumption enterprises by 40%, significantly reduce the number of 'hot spots' and reduce the urban population living in unfavorable environment. Warm and snowy winter complicate flood situation in Russia in 2009, moe Russia predicts that because of the warm and snowy winter, the flood situation in Russia this year will be more complicated compared with the previous year. The winter of 2008/2009 was characterized by warmer temperatures in winter (on average 2 degrees), as well as excessive by several times of precipitation. That is what will affect the threat emergencies caused by floods. The most difficult situation with floods expected in the Krasnodar region, as well as in the area of the Ob, Lena, Yenisei, Irtysh, Angara. Roshydromet expects that floods on the rivers of southern Russia will begin in mid-March – for 5-10 days before the medium-long-term performance. In the second decade of March to begin flooding in the basin of the Don river basin and Kuma, which will continue until June. Floods on the rivers of Dagestan will begin in late March – the first of April and continue through September.

On the lower Volga River floods begin in April with an increase in discharge through the Volgograd hydroelectric and river levels will depend only on the magnitude of these discharges. In RosHydroMet noted that the greatest danger for subjects rain floods are going against floods, the most dangerous period of the passage of which will be in May-August. The quality of drinking water in Moscow significantly improved since 2011 Concept Program Clean Water Moskvy for 2010-2012 endorsed last week by the Moscow authorities. Eva Andersson-Dubin, New York City is actively involved in the matter.
