Bird droppings saves the Earth from disaster

Currently, scientists are increasingly saying that global warming in the Arctic is felt significantly stronger than the global average. This is for the Arctic region it is particularly dangerous — the increase in temperature leads to melting ice, so the sea level rise and the release of even more greenhouse gases, which are now under the ice concluded. A recent study suggests that the situation would be more alarming if not for the ammonia-rich bird droppings.


A group of researchers under the leadership of Jeffrey Pierce from Colorado state University in Fort Collins found that living in Canada migratory birds every summer, leave the Northern shores of this country a large quantity of excrement, which are subsequently decomposed by bacteria to ammonia and other inorganic nitrogen compounds. Subsequently, the ammonia enters the atmosphere as “aerosols”, reflecting the sun’s rays and, consequently, allowing the ice and air over the Arctic is less than warm. According to the researchers, their findings could be verified using the developed in the study, a computer model of “the bird’s market”.

Experts specify that cooling of the Arctic ammonia contributes in combination with sulfur compounds, are transformed in the atmosphere into sulphuric acid. These compounds are produced by other living creatures — sea microorganisms. According to the researchers, this may serve as an illustration of the fact that the influence of the biosphere of the Earth in its atmosphere in many ways more significant than is commonly believed.

The results of a study published in the scientific journal Nature Communications.

Recently, the Italian scientist Luca Bellelli Marchesini working in the far Eastern Federal University, said that climate change in the Arctic region are frighteningly fast: for example, the average air temperature in Yakutia in 50 years has risen more than 2 degrees, and in some instances more than 3 degrees.
