Teachers TV- Climate Change - The Causes
https://www.youtube.com/watch?v=RHrFBOUl6-8
Planet Earth is about 4,5 billion years old!
The temperature of the Earth has changed many times during its life, changing the global temperature(climate). These changes happen naturally and are caused by changes in the amount of energy that our planet receives from the sun or from events such as volcanic explosions.
What causes climate change?
The cause of climate change is the excessive use of fossil resources such as coal and lignite, oil and natural gas, the burning of which releases huge amounts of CO2 into the atmosphere. In this way the “blanket” of “Greenhouse” gases covering the Earth, holds more and more energy which, in its turn, increases the average temperature of the planet.
The temperature changes are derived from a combination of natural events(facts) and climate change caused by Man. Sometimes both factors causing warming on earth and sometimes some natural events can cool down a little bit the planet and to disguise(cover up) or hide the effects of climate change which caused by human. But such changes and the increase in the Earth continuously heated. The 9 warmest years in the history of the planet have been between 1997 and 2007.

Greenhouse Effect What is the Greenhouse Effect?
What is the Greenhouse Effect?
The term Greenhouse is used in conjunction with the phenomenon known as the Greenhouse effect.
Energy from the sun drives the earth’s weather and climate, and heats the earth’s surface.
In turn, the earth radiates energy back into space
Some atmospheric gases (water vapor, carbon dioxide, and other gases) trap some of the outgoing energy, retaining heat somewhat like the glass panels of a greenhouse.
These gases are therefore known as Greenhouse gases.
The Greenhouse effect is the rise in temperature on Earth as certain gases in the atmosphere trap energy.
When did start the Greenhouse Effect?
Greenhouse gases started millions of years ago, before life began on earth. They keep the planet warm enough for life, through the natural carbon and water cycles of the planet. Human began producing greenhouse gases about 260 years ago, at the start of the Industrial Revolution, when we dug up durned coal and oil for industry, transport and later for the generation of electricity. These fossil fuels are releasing extra greenhouse gas which is now overwhelming the natural carbon cycle.
Svante Arrhenius (1859-1927) was a Swedish scientist that was the first to claim in 1896 that fossil fuel combustion may eventually result in enhanced global warming. He proposed a relation between atmospheric carbon dioxide concentrations and temperature. He found that the average surface temperature of the earth is about 15oC because of the infrared absorption capacity of water vapor and carbon dioxide. This is called the natural greenhouse effect. Arrhenius suggested a doubling of the CO2 concentration would lead to a 5oC temperature rise. He and Thomas Chamberlin calculated that human activities could warm the earth by adding carbon dioxide to the atmosphere. This research was a by-product of research of whether carbon dioxide would explain the causes of the great Ice Ages. This was not actually verified until 1987.

Climate changeWhat is the climate change?
What is climate change?
Climate change is a significant and lasting change in the statistical distribution of weather patterns over periods ranging from decades to millions of years. It may be a change in average weather conditions, or in the distribution of weather around the average conditions (i.e., more or fewer extreme weather events).
Today when people talk about climate change beyond the sun or volcanic explosions. They talk about the changes because of human activities and starting from the time when coal was first used to give energy in industry.
Global warming and climate change refer to an increase in average global temperatures. Natural events and human activities are believed to be contributing to an increase in average global temperatures. This is caused primarily by increases in “Greenhouse” gases such as Carbon Dioxide (CO2).
A warming planet thus leads to a change in climate which can affect weather in various ways(, as discussed further below).

What are the main indicators of Climate Change?
There are 7 indicators that would be expected to increase in a warming world:
Tropospheric Temperature
Humidity
Temperature Over Ocean
Sea Surface Temperature
Sea Level
Temperature Over Land
Ocean Heat Content
and 3 indicators would be expected to decrease:
Glacier
Snow Cover
Artic Sea Ice

Everything starts from 1 person, but the results come from a group of people!
So what do you think, would you like to stop at this point or to GET INVOLVE?
Tusen Takk!Merci beaucoup! ክብረት ይሃበለይ!Большое спасибо!Τak!Ευχαριστώ πάρα
πολύ!Thank you very
much!
