Bacteria under ocean bottom
Bacteria under ocean bottom – American geologists from Oregon, performed in Atlantic oceanic crust (where the temperature is approx. 102 ° C) drilling to a depth of 1,391 m. Among granitic igneous rocks found relatively rich bacterial ecosystem. Bacteria feed on methane and benzene there.
Biogas plants aren’t tight
Biogas plants aren’t tight – In Poland there are over 200 biogas plants. Which produce almost 300 million cubic meters of biogas per year. Biogas plants aren’t completely sealed: escaping from them, methane. The most important source of energy in biogas produces a greenhouse effect, 25 times stronger than carbon dioxide. And also formed in this process, nitrous oxide has 300 times the even greater potential of causing global warming than CO².
Melting glaciers – Associated with rising sea level
Melting glaciers – Associated with rising sea level – One of the most visible effects of climate change is melting glaciers and the associated rise in sea levels. According to the Intergovernmental Panel on. Climate Change, if we do not reduce the production of greenhouse gases. The level of the oceans by 2100. Could increase by as much as 98 cm. If, however, we limit the production of gases, the water level would increase by 28 – 61 cm. The melting of ice in Antarctica could lead to the extinction of two-thirds of the population of the polar bear (Ursus martimus). In addition, the glaciers will release methane, which is also a greenhouse gas. A reduction in ice cover open while the road between the Atlantic and Pacific, and will make further deposits of raw materials.
Martian methane – Detected in meteorites from Mars
Martian methane – Detected in meteorites from Mars – Canadian researchers from the University of Brock, in six meteorites from Mars have detected the presence of methane. The researchers also found traces of carbon dioxide, hydrogen, nitrogen, oxygen and argon. Methane was formed in meteorites probably under the influence of chemical reactions, so it is not of biological origin as methane on Earth. Scientists believe that the volcanic rocks of Mars there are large quantities of methane, which could be a source of energy for underground microbes. This confirms the theory that the Earth there are microbes that live thanks to methane. They live on the bottoms of the oceans in layers of basalt and do not need oxygen. Signals the presence of methane in the Martian atmosphere appeared more than 10 years ago, but so far have failed to unequivocally confirm.
