Carbon Neutralization (I)

Tell me about the changes in the earth.

In the past 1000 years, the temperature of the earth has actually been very stable, but since 1900, the earth has started to heat up obviously. This is also a century in which the temperature has risen so much since human beings began large-scale industrial production 100. How much is this big hole?

Once, yes, you heard me right, it was once. In fact, in more than 500 million years, the temperature of the whole earth has only changed by about 22 degrees. Humans can influence one of them in just over a hundred years, which shows that human influence is really great. But will it really have a great impact at this time?

In fact, there is nothing so far. There was a rise of six or seven degrees in Cretaceous, and most species actually adapted. So the temperature effect of global warming was controversial before. Some countries signed the Kyoto Protocol in 1997, but failed to abide by it. Maybe they just think that this is not a big problem, and it will also affect their own economic development.

In 20 15, all countries in the world signed the Paris agreement, and now all countries in the world have announced that they will achieve carbon neutrality. It seems that they suddenly reached an agreement and will resolutely implement it. What's going on here?

During the Cretaceous period, the rising temperature of six or seven degrees took millions of years to rise slowly, and the species had enough time to adapt slowly, but if the rising speed was too fast, you can imagine, can it adapt? I can't get used to it. At present, it seems that the increase is not a big problem, but if it increases by 1.5 degrees, it will reach a very dangerous critical value. There are many factors that affect the change of the earth's temperature, including these (Amazon rainforest, North American boreal forest, Atlantic circulation, global coral reefs, Arctic sea ice, Greenland ice sheet, Antarctic western ice sheet, eastern ice sheet, permafrost) and so on.

These are the most important. Among them, in addition to more glaciers melting and rising sea levels, there is a particularly important permafrost layer, which is like a huge carbon freezer. The frozen carbon is about twice as much as the carbon content in the earth's atmosphere now. If it begins to melt, it will release a lot of carbon dioxide and methane, and the sudden change of temperature will make any living thing too late to adapt. Now I have basically reached the understanding of * * *. That is, if the temperature rises by two degrees, it will probably reach this critical value, and it is safer to control it within 1.5 degrees. The goal of global carbon neutrality is the same, which is to control the temperature rise of the earth within 65438 0.5 degrees from now on. In fact, it's no good if the temperature rises, and it's no good if the temperature drops. As early as CAMBRIAN, when the temperature was suitable, there was a species explosion, but in Permian and Triassic, the temperature dropped twice, leading to species extinction. More than 70% of terrestrial life and 96% of marine life have all disappeared. Neither high nor low, so what should we do?

In the face of nature, human beings should remain in awe. Carbon neutrality is actually to offset the carbon emissions produced by human beings and give nature a zero. The earth itself will create a dynamic balance and maintain it for hundreds of thousands of years without worrying that it will devour us. As long as we take care of ourselves, we are self-confessed.

When we face the common problems of all mankind, it is actually very easy to reach a consensus, so those so-called disputes and contradictions are nothing in front of nature. What's more, we ordinary people, what can we care about …
