"Biosphere-2" - construction, modeling a closed ecological system, built by «Space Biosphere Ventures» and billionaire Edward Bass in the desert of Arizona (USA)
The laboratory is a network of sealed buildings with a total area of 1.5 hectares of lightweight materials, divided into several independent ecosystems and covered with a glass cover, which transmits about 50% of sunlight. Interior space is divided into 7 blocks, among them - the rain forest, a miniature ocean with an unusual chemical composition, desert, savanna and mangrove estuary. Giant "light" regulate the internal pressure in such a way as to conform to the outside - it minimizes air leakage.
Eight people (four women and four men) stayed in the "Biosphere-2" for about two years, maintaining contact with the outside world only via computer. Together with them there were also delivered to 3000 species of plants and animals.
However, after several weeks of life of people living in subsistence farming, disrupted. Microorganisms and insects began to thrive in unexpectedly large numbers, causing an unexpected oxygen consumption and destruction of agricultural crops (use of pesticides is not envisaged). Inhabitants of the project began to lose weight and suffocate. The scientists had to go to a violation of the conditions of the experiment and begin delivery into oxygen and food (these facts were hidden, and were subsequently exposed). The first experiment failed: the people have lost much weight, the amount of oxygen decreased to 15% (normal content in the atmosphere - 21%).
Observed problems
The laboratory has bred a lot of germs and insects, especially cockroaches and ants.
Under the glass roof of the complex in the mornings condensed water and poured artificial rain.
The creators did not envisage such a thing as wind: it turned out that without regular swaying trees become brittle and break.
The Copenhagen conference of global warming is over. Many believe
that the issue was not resolved, why? See photos and all will become clear.
The first decade of the 21 th century was the warmest on record for weather in the United States. This is with reference to NASA experts said Friday TV CNN.
Scientists at the Goddard Institute for Space Studies in American space agencies also found that the warmest since 1880, when scientists with the invention of various devices the opportunity to conduct systematic and more accurate weather observations began in 2005. The second highest rate was the last, in 2009, stressed the experts.
In the first decade of the century, the coldest was in 2008. This was mainly due to the influence of climatic phenomenon La Niña, which has caused a strong decrease in temperature in eastern and central Pacific Ocean.
The study emphasizes that the temperature on earth increased by 0.6 degrees over the past three decades and 0.8 degrees over the past century. In this regard, it is safe to say that global warming is taking place slowly and with considerable fluctuations over the past century until 1975, but then was observed its rapid acceleration - to 0.2 degrees Celsius per decade, say experts .
"Every year we observed that the temperature fluctuated depending on the phenomena of El Niño and La Niña. However, when it became clear that the average temperature for five to ten years do not correspond to cycles of these phenomena, we found that global warming continues unabated, "- noted the director of the Institute, James Hansen.
In compiling its report on climate change, scientists from the Goddard Institute for Space Studies used the data of thousands of weather stations around the world, testimony to the meteorological surface temperature of the seas and oceans, as well as information obtained by scientists at research stations in Antarctica.
