I do not know we know now, the global climate is warming, the summer in recent years to the very back, and the average temperature is high. Really like the article, described the film as heat. Leaves by exposure volume up, people have very little to stay out of the room air-conditioning, and many animals were Shaisi the … … these are not real things look has quickly become a reality. This can explain anything? Why is global climate change with it so hot? I would like nothing more than call the following aspects.
1. The impact of human activities
The 21st century is a century of human science developed, it is because more and more progress in human life, so human beings on the planet led to less and less attention to environmental protection. Although aware of the seriousness of the human, while vigorously promoting the need to protect the environment, it is still hard to detect ah! For example, some black heart manufacturers to save money, do not put treated wastewater, smoke, garbage, discharged to the natural world, such is life, well, cars are generally, but the tail gas pollution can be so indispensable. This does not, almost all scientists agree that human activity is causing climate warming, but climate warming is gathering a lot because the atmosphere of greenhouse gases, mainly carbon dioxide. The most obvious evidence is that the concentration of atmospheric carbon dioxide: Carbon dioxide in the atmosphere according to the concentration of target PPM, a 1 million years, the index has remained at about 270, about 40 years to the index hovering between 200-280, can be Since the industrial revolution began, the index soared, reaching 360 now, and this index will increase, so will be hotter.
2. Plants release large amounts of methane of
When I saw the “Earth plants release large amounts of methane on global warming and more severe than carbon dioxide. This is not the understanding of the trees and plants died and decayed to produce the gas. The gas from the process of plant growth natural side effects, but scientists have overlooked this very important point. According to preliminary statistics, the existing trees and plants into the air in the methane share of global gas ratio of 10% to 30%. “This makes me surprised the news is simply not being believed , arguably plants can help us the air of human evolution, but actually … … hey! We have only one Earth ah! Although the cause of global warming for many reasons, but is closely related to human is, if in so go on, those fantasies of disaster will be closer to us. Here I would like to appeal to everyone: “From my start, protect the earth!”
