Greenhouse schematic

Global warming affects the Earth is comprehensive, the most obvious is to feel the temperature increased, but why the temperature will increase, which is closely related to the Earth "greenhouse effect", in general, as long as the atmosphere of the planet will have a greenhouse effect appropriate greenhouse effect, the planet is maintained at a temperature suitable for living organisms, too, if the greenhouse effect, Earth's overall temperature rise caused by global warming.

What is the greenhouse effect?

Like the greenhouse effect often used in agriculture to maintain the space temperature of the greenhouse, the Earth's atmosphere as greenhouse plastic sheeting, will surround the Earth into a greenhouse, when solar radiation through the atmosphere to the surface, some will be reflected back to the light and heat the space, the atmosphere at this time that some gases absorb heat and light, and is reflected back to the surface of the earth, so the earth is maintained at a certain temperature. The atmosphere absorbs light and heat of the gas, we called "greenhouse gases."

Global warming may happen?

Global warming is now performed formula, some people argue that the problem is that it is natural or man-made? Last year 'Intergovernmental Panel on Climate Change (IPCC), "the United Nations (Intergovernmental Panel on Climate Change, IPCC, 2007 Nobel Peace Prize winner) collection of huge human and material resources, the use of computer climate models after reckoning, in the latest" Climate Change assessment report, "said : global warming almost certain (95% chance) is caused by humans.

Who is affected?

"Global warming" has a special feature: the first is the poor people had to live, they do not enjoy the fruits of economic development, they have to withstand waves of famine, war  rich countries can temporarily pretend nothing, continued burning of fossil fuels, and carbon dioxide emissions, in exchange for room air conditioners peacefulness of life afflicted with life, the whole world is a disparity M-shaped society. This is not "robbing the poor to the rich," and what is "robbing the poor to the rich"!

If carbon dioxide emissions by area representatives of the country (top), and the number of death due to climate change (below), then this is the map of the world, respectively. Ironically, a large number of casualties is not carbon dioxide manufacturing country, Africa, India, the biggest casualties.

More trees, use of renewable energy sources like ??

IPCC report suggests global changes should be fully within 15 years of energy production, transfer from carbon-intensive fuels to wind, solar, nuclear and carbon capture technologies exist (to the recovery of carbon dioxide in the exhaust gas, stored somewhere) of thermal power plants and other low-carbon energy. If we again and again a decade, the cost of stabilizing the climate will become very expensive, Earth forever into an alien planet. In addition to a carbon tax in accordance with the amount of additional product carbon dioxide emissions, the real cost of carbon dioxide emissions reaction. Hot little people die?

"Global warming" will only make the impression as if the poles melt, sea level rise, polar bears will be killed, resulting in the most extreme weather only. UN study reported noted that temperature increases will cause some infectious diseases more rampant. The United Nations World Health Organization estimates that global warming caused more than 14 million deaths in the year 2004; in Africa, the number of additional deaths due to malaria by 2030 to reach 170 million, while the number of dengue infection worldwide in 2080 will be more to 2 billion. Climate change can also cause large-scale food production, fisheries collapse, and even lead to war over resources. Scientists have indeed found the history of the temperatures rise, the war turmoil have increased. When these disasters occur, people will accuse visible scapegoat, will not notice the enormous environmental invisible black hand behind. Like a physical deterioration, often sick people, but only you know piecemeal gap measures. IPCC pointed out that if people do not take action to reduce carbon emissions, the Earth's temperature will accelerate the rise in the 21st century can be further increased 4 ° C, sea level rise of nearly 1 meter. Just after the IPCC report, the scientists also found that several glaciers in West Antarctica have already began to collapse in global sea levels could rise by 4 meters extra 200 years, has been unable to save the human. I'm afraid the United Nations sharp correction expected to disasters, human civilization at stake.

IPCC predicted global average temperature. Black line on the left past the amount obtained by the temperature, the right of the red line can be seen as human beings do nothing result, the temperature is about to rapidly rise, almost everyone can live to see the disastrous consequences;? Blue line is in accordance with the IPCC We recommend that the results of 15 years of effort, or slow down global warming. (Source: IPCC AR5 WG1 Figure SPM.7a)
