World tends to the era of dinosaurs

July 2012 will be remembered many of the tragedy in the Kuban. Heavy rain hit the towns of the Crimean region, Novorossiysk, Gelendzhik, which led to the exit of the river banks and outright floods. From climatic disaster suffered tens of thousands of people.

Environmentalists believe that the enhanced precipitation due to climate change, more powerful and unpredictable are almost all natural elements. But most importantly, as experts believe, humanity will be increasingly exposed to such natural emergencies. All of the natural climate system is out of balance.

In the Kuban flood occurred due to a combination of many factors: the natural disaster to negligence and lack of training institutions responsible for the safety of the public land.
Climate change may cause other natural disasters: the abnormal drought, avalanches and floods, increased volcanism, hurricanes, storms, earthquakes, tsunamis, forest fires, tornadoes, etc., and these disasters can occur suddenly and with great human and losses.

Variations in climatic conditions on the surface of the Earth or in particular regions is expressed in deviations from the parameters set forth in the result of many years of observations. In Russia there is a statistical climate records, which also contains information about the average weather terms, changes in the frequency of extreme climatic events. There is even a science dealing with the study of changes in weather conditions, called paleoclimatology.

It is believed that the main causes of climate change are dynamic processes on Earth, external forces — such as, for example, solar radiation, and of course, the activities of mankind.

Thus, the climatic factors of climate change on Earth are: freezing, shifting of the oceans, the climate memory.

Non-climate factors of climate change are: the impact of greenhouse gas emissions, the mobility of lithospheric plates, the solar radiation, changes in the planet's orbit, volcanic activity.

Oh, and human factors (ie, the effect of human activity) of climate change are: fuel combustion, the use of aerosols, emissions of cement industry, barbaric land, livestock, etc.

In the early 21st century, the nature unleashed a series of disasters on mankind and it seems this will not be the end of the test. Revived in 2010, the Eyjafjallajökull volcano paralyzed air travel the whole EU, the earthquake in Haiti, floods in Pakistan and the fierce heat in the European part of Russia, led to the deaths of 260,000 people and huge economic losses.

The earthquake, which occurred in 2011 in Japan, killing more than twenty thousand people, inflicted heavy damage to the economy.

Land along with natural disasters rocked technological and social disaster: the oil spill in the Gulf of Mexico, terrorist attacks, which killed thousands of innocent people, revolution, insurrection, military operations. The frequency of these tragedies is widening whether humanity stop or slow these misfortunes and disasters.

The scientists hypothesize the possible scenarios of climate change on Earth.

First. Earth is a very complex system consisting of interconnected components: an ever-changing atmosphere, complex air flow, the activity of the world's battery heat and gases — the oceans. The changes in this complex system is slow, so there is time for humanity to take action to curb global warming.

Second. If we consider that in the last century the average temperature of the planet has increased by one degree, the concentration of carbon dioxide has increased by 24%, by the end of this century, the Earth's temperature could rise by 6.4 degrees. Accelerate the melting of the Arctic and Antarctic. But these white defenders of the planet by reflecting solar flux cool the planet by 2 degrees, and the ice covering the ocean regulates the processes of heat exchange in the world. If warming is not stopped, by the end of the century rise of the oceans from melting ice will rise by 50 cm, which will lead to flooding of coastal areas, especially the coast of Asia could suffer. Also, global warming will affect the strength of the wind will change rainfall patterns and seasonal areas (will be common in the Mediterranean heat and drought in Europe, winters will become warmer, and summer is rainy, etc.), severe storms, floods and droughts will fall to the new the power to the ground.

Third. Known fact that the speed of oceanic currents is dependent on the temperature difference between the Arctic and tropical waters. If the difference is a result of global warming is reduced, then slow down the ocean currents, which had such tragic consequences for Earth's climate. For example, to stop the Gulf Stream may cause a temperature increase of 2.5 degrees. The consequences of this will be truly catastrophic — the climate of Northern Europe will be colder, storms intensify, the fate of rain.

Fourth. Stop "European warmers" — Gulf Stream — will lead to the land of the Ice Age.

Fifth. Warming will cause an increase in carbon dioxide in the atmosphere, there will be expansion karbonadnyh rocks, increasing the transition to the additional CO2 atmosphere, besides the melting of glaciers in the atmosphere will come methane. As a result, the Earth's temperature will be about 150 degrees, and it will destroy not only human civilization on the planet, and all living organisms.

Yet there is no certainty that the blame for these natural disasters people. Mankind has no experience in dealing with such problems. Now all interested parties must move in their proposals in almost complete darkness, and very careful not to cause irreparable damage to the planet. Everyone understands that currently required to adapt to climate change, to minimize the negative impact of climate change, learn to use the benefits of these changes.

To that end, you want to receive all necessary information from many sources: from historical documents (chronicles, annals), from the statistics of meteorological measurements, the data obtained from satellites (of sea ice, atmospheric processes, climate zones), paleontological research, materials study ocean rocks, the study of ancient ice north and south poles of the Earth, control information melting of glaciers, icebergs and statistics state of permafrost, evaluation pattern of ocean currents, the monitoring of the chemical composition of water, flora and fauna of the planet.

If time does not take action, humanity prepared, at best, a return to the era of dinosaurs.
