Hot weather

Many friends still remember how hot it was last summer. The temperature in South Asian countries such as India is often 40-50 degrees Celsius, and the temperature in West Asia, North Africa, Europe and other countries has also hit record highs. Most of the ice shelves in the Arctic Circle and Greenland have melted, and the warning of global warming is naked in front of us.

It may be related to the development environment in the world, because the development causes the emission of harmful gases such as tail gas, which leads to the emergence of environmental greenhouse effect, which in turn affects the rise of global greenhouse effect, which leads to the intensification of global greenhouse effect and global warming. Then glaciers melt and red snow appears, and the temperature in other areas is gradually rising.

Many years ago, scientists began to try to understand the possibility of various meteorological events with the help of computer models and various factors. After dozens of studies, it has been proved that 25 kinds of climate phenomena are related to greenhouse gases produced by human activities, which in turn lead to climate warming. ?

Greenhouse gas emissions directly induce extreme weather?

In fact, the story behind it is far more than that. Global warming caused by human beings is the most fundamental reason. John nelson Gamon said that compared with 1970, the global temperature rose by an average of 0.5 degrees Celsius, which was mainly due to the massive emission of greenhouse gases into the atmosphere. It is this rising temperature that causes some extreme heat waves, droughts and other extreme weather. Besides, there is little rainfall now. Why? Warm? The weather has added another fire.

In addition to glaciers, global warming will also lead to the melting of permafrost. Many frozen animals in history will be exposed to the air, and some ancient viruses may be released. Some scientists believe that the outbreak of COVID-19 is related to the ancient virus released by permafrost.

Some people think that the temperature rise in the Arctic is an accidental phenomenon, but in fact, the temperature in the Arctic has hit record highs last year. The temperature of more than 30 degrees has appeared many times, and several famous ice shelves in Greenland have all melted away. There is no reason behind this! The most traceable reason is the increase of carbon dioxide caused by human activities, which leads to global warming. The problems caused by a series of effects are realistic and urgent, and human beings must make plans and actions for global warming.
