How to identify constellations

Being able to recognise the constellations in the night sky can be a lot of fun and also very useful.

From ancient times, mankind has seen patterns in the stars. Getting to know these star patterns can help you feel at home in the night sky and being able to recognise just a couple can help you find many others and help you become familiar with them.

In the past, every culture had its own way of seeing patterns in the stars. These patterns, or constellations, were connected with stories and folk legends. In the west we have settled on

Snow cover on the planet has reached its minimum

Snow cover on the planet has reached its minimum Facts

As the analysis of satellite data, in Eurasia, since 2008, in June, has been a steady reduction in snow cover. Three of the last five years in the same state of the snow mass in North America.

Indications of satellites in 2012 were the lowest in all the 45 years of observation. The rate of disappearance of snow, even more than the rate of melting of the Arctic ice in the summer. Now the snow in the northern hemisphere is melting much earlier in the spring than before,

In the Indian Ocean formed a rare cyclone

In the Indian Ocean formed a rare cyclone Weather and Climate

Tropical cyclone Anais with maximum wind speed of 184 km / h, which is equivalent to the Atlantic hurricane third category of danger, appeared in the south-west Indian Ocean. In early spring, and it is this season going through the southern hemisphere of the Earth, tropical cyclones are rare, which makes the appearance of Anais anomaly. This can be compared with the sudden emergence of a powerful hurricane in April, somewhere near the Caribbean. But unlike the hurricanes of the northern hemisphere, Anais rotates clockwise.

Typically, in

January 23, 2013. According to the American meteorological monitoring, the combined average global temperature Earth surface December was +12,61 ° C, which is 0,41 ° C higher than the average for the XX century. With this measure December 2012 ranks only 18th place in the climate history.

Separately, the global average for sushi temperature to 0,21 ° C higher than the average for the XX century and was almost in the middle of a number of ranked, ranking only 49th place in history.

Climate warming leads to an increase in the amount of snow in Siberia

January 17, 2013. Global climate change leads to a widening of the snow cover Northern Hemisphere and in Siberia, said Thursday the director of the Institute of Geography RAS Vladimir Kotlyakov, speaking at the World Forum of snow.

"There is a paradox — a warming that is now characteristic of the world becomes more snow. This occurs in large areas of Siberia, where the snow is more than it was a decade or two ago, "- said the honorary president of the Russian Geographical Society Kotlyakov.

According to the geographer, the trend expansion area of snow in the Northern

From landslides killed 10 times more people than previously thought

According to a British study published August 14, 2012, the number of victims of landslides in 10 times more than previously thought. The vast majority of deaths occur in South Asia, Latin America and China.

In the period from 2004 to 2010, worldwide there were 2620 landslides took the lives of 32,322 people. As reported by researchers at Durham University in northeast England, estimates are preliminary. Landslides often occur in the summer in the northern hemisphere, particularly in the Asian monsoon. Most often, the victims are residents of overcrowded slums built on cleared slopes. The most dangerous areas

Confirmed the relationship between the warming in the Arctic and cold winter in the Northern Hemisphere

An international team of researchers has discovered a new link between the melting ice in the Arctic and cold winter in the Northern Hemisphere. SUT $ $

Since 2007, the area in the summer ice of the Arctic Ocean reached a record low, the northern U.S., in the north-western and central Europe, as well as in northern and central China have from time

Why global warming is here and leads to cold?

It is well known that global warming causes cooling of some parts of our wonderful planet. Shed light on the nature of this paradoxical mechanism could creator climate models Judah Cohen of the consulting firm Atmospheric and Environmental Research (USA) and his colleagues.

Global average temperature increases since the late XIX century. Fastest warming in the last forty years, and the Arctic is warming almost twice smarter than the rest of the world. Despite this, the winter in some parts of the Northern Hemisphere were colder — see, for example, southern Canada, the eastern United States and parts

Scientists have discovered the Earth climate swings

Climate changes in the northern and southern hemispheres of the Earth forms a kind of "climate swings" — warming in the north leads to a cooling in the south and vice versa, due to the change in the circulation of water in the Atlantic Ocean, they said the study published in the journal Nature.

As established by the authors, researchers from the UK, Germany, France and the U.S., a sharp drop in temperature in the northern hemisphere during the last glacial period (100-15 thousand years ago), accompanied by a simultaneous warming in the southern hemisphere. Scientists have found out
