GLOBAL WARNING!Humanity causes Global Warming?

Last time I’ve been worrying about “where the human is going” or “what is our end is” .It might sound funny, but I just want to write about it ,I want this article to be read and take it seriously, also it will help me to get rid of such a thoughts.I’ve searched many sources to show you how much this issue is important, but also I don’t want you to have such abtrusive thoughts like I do.My article is about an issue of Global Warming and what is written below is something like a collection of researches, claims, scientific developments and researches.

Scientists claim that the last climate changes are the result of Global Warming that is caused by human activity mainly.The Earth had global warmings several times before.And everytime it continued with climatic temperature drops.The last Icy Period caused an end to many biological forms.I don’t think human being would survive at such climatic temperature drops as the Icy Period.Of course this the thought of a pessimist, however it is clear that the another Icy Period might become the end for human being, but do not panic, it will happen after approximately 800-1000 years. 

So what reasons has the Global Warming?

The main reason for global warming is the greenhouse gases, scientists claim.It’s clear that people are the main polluters of the nature.It is known for science that adding the water, carbon dioxide and methane into the atmosphere will rise the temperature.However, these gases create natural greenhouse effect without wich the temperature of the earth’s surface would be to 30 C below wich would make it unfit for life on the earth.Carbon power stations, automobile exhausts, plant smokestacks and other created by humanity sources of pollution together vent to the atmosphere approximately 22 billion tons of carbon dioxide and other greenhouse gases per year.Stock raising, the application of fertilizers, combustion of coal other sources give about 250 million tons of methane per year.About half of all greenhouse, rejected by humanity, it remained into the atmosphere.From the preindustrial period of the middle XVIII of the century of concentration of carbon dioxide and methane by 31% and 149% respectively.

 How much the climate has changed?

Scientists proved that the average temperature by Earth has grown up to 0.2-0.6C since the end of XIX century.Also the researches claim that the average temperature on Earth will grow up from 1.4 to 5.8 C between 1990 and 2100 years.As the result it will cause big climatic changes such a rising of level of World Ocean.Also, you can compare the warm winter nowadays with the winter of 1995th. So, you see how much the climate has changed and you can expect warmer winter next year.

So, we can not change the way that the climate is going on, anyway even the level of exhaust of your car can change the speed of climate changing.Unfortunately, not everyone of us cares about the consequences of polluting the air.
