The Threat of Global Warming May Lead to Global Cooling

In the past few years, most people have heard that the earth is warming. In addition, nearly everyone has heard the request of former Vice President Al Gore for environmental protection and carbon reduction. According to Laurence Pringle's book "The Global Warming Evaluation of Greenhouse Threats" (19), even without the true exact definition of global warming it can be defined as roughly global mean temperature rise. The global warming assessment of the threat of greenhouse effect also shows that the average temperature data used by scientists can only be traced back to 1860 and provides scientists with only 150 year temperature data.

"I am not opposed to global warming, global warming has occurred frequently in the 1930s and 1940s, and there was a slight global warming since the mid 1940s to the beginning of the 1970s since the mid 1970s This is natural because of global warming, especially in the past decade, but due to changes in the circulation of the ocean, etc. It is not human fault. "About 40 to 50 years colleagues are concerned about global warming as a whole I am skeptical. Things but no one asked us. If you do not know anything about how the atmosphere works, it goes without saying, "Look, the greenhouse gas is rising, the world is warming, they have to be involved." Changing a symbol does not mean that one is causing the other. "

People will consider the term global warming and you may think that the words are experiencing relatively average warmth in our world. Global warming can pose a potential threat to the environment and its environment. Rather, global warming can be widely described as rising earth's atmosphere and surface temperature, which can lead to changes in the Earth's climate caused by greenhouse gas emissions. The fact that global warming plays an important role in it

Worldwide, ABC's surface cooling effect masks 47% of global warming caused by greenhouse gases and the range of uncertainty is 20-80%. This is a dilemma, as it will obscure the cooling effect of ABC when trying to suppress air pollution and worsen the surface warming. Therefore, we should make efforts to reduce greenhouse gas and air pollution in a common framework. Our uncertainty about the effect of ABC is great, but we are discovering a new way that human activities can change the climate and the environment.
