Ask for a debate on global warming, and I m square

In recent years, scientists have pointed out that the global climate warmed significantly in the 20th century, and that average temperatures have risen now compared to the beginning of the 20th century. It is true that the global climate has been warming throughout the 20th century, but is it because of the "greenhouse effect"? Will it continue to warm?

Scientists have their own opinions on this.

Some scientists believe that the warming of the 20th century is a continuation of the "Xiaoice" temperature rise, the result of natural evolution, and has nothing to do with the "greenhouse effect".

These scientists believe that in the 4.6 billion years of the earth's existence, the climate has always changed, and it has changed at different scales and cycles, and that the warming of the climate in the 20th century is a normal natural phenomenon, after which the temperature will naturally decrease.

However, there are many scientists who oppose this view, arguing that global warming is due to the "greenhouse effect", and that humans are the main culprits of the "greenhouse effect".

They believe that in recent decades, the rapid development of industry and manufacturing has greatly increased the amount of carbon dioxide emitted into the air by humans. In addition, green plants, especially forests, have been greatly damaged and cannot absorb a large amount of carbon dioxide emitted by humans, so the concentration of carbon dioxide in the atmosphere has increased greatly, hindering the heat exchange between the atmosphere and the ground, causing the "greenhouse effect". Moreover, the authoritative organization IPCC (Intergovernmental Climate Change Group) has conducted a large number of detailed studies on the problem of global warming, and clearly pointed out that the increase in carbon dioxide content in the atmosphere is the main cause of global warming.

Although many parties now support the "greenhouse effect" as the cause of global warming, many scientists believe that the earth is currently developing in the direction of low temperature and humidification. They argue that although the temperature in the 20th century generally showed an upward trend, the change in carbon dioxide concentration did not exactly coincide with the change in the temperature curve, and there was a cooling process in the 40s and 80s of the 20th century.

They provide evidence that, on the one hand, climate change is influenced by the Earth's own feedback mechanism, which will exchange heat on its own and thus digest carbon dioxide; At the same time, due to the extremely humid air, the parts of plant residues that cannot be decomposed are stored in the earth's crust in the form of peat, thus forming the transformation of carbon from the biosphere to the geosphere.

On the other hand, the water vapor produced during the temperature rise increases the water content of the atmosphere, forming some clouds, and a large amount of solar radiation will be reflected and scattered by these clouds, thereby alleviating the temperature rise.

Meteorological systems are very complex, and I believe that one day we will understand the truth about global warming and improve the environment on which we live.

It is indeed very difficult to be an opposing debater.

In my humble opinion, it is true that the cause of the greenhouse effect is caused by excessive emissions of carbon dioxide and other exhaust gases, and there is no point in arguing in this regard. But you can express your opinion on the consequences of the greenhouse effect.

How harmful is the greenhouse effect to human beings?

In the past, people used a simple linear system model to think about the greenhouse effect, thinking that in the Earth's climate system, a single disturbance would cause the collapse of the entire system, just like a domino effect. However, in the 21st century, with the development of chaos science, people realize that the change of the complex system of climate is nonlinear and will have a self-organizing effect, that is, for the disturbance of the greenhouse effect, the earth's climate will undergo some changes, but it will not enter a vicious circle, it will not collapse, and the earth's climate will adjust itself and enter the next stable state.

Here's a quote from the encyclopedia: In recent years, there have been significant improvements in the modelling capabilities of climate models, which take into account the role of atmospheric aerosols (tiny particles suspended in the air). This is because burning fossil fuels releases CO2 and also releases huge amounts of aerosols such as sulfides.

This aerosol blocks some of the sunlight from reaching the ground, thus lowering the air temperature on the ground and cooling it. The value is estimated to be up to W2 according to the IPCC. This is equivalent to 1 3 of the CO2 warming effect (W2) and slightly larger than the methane warming effect (+W2).

Mainly based on this improvement, the IPCC revised the warming value of the global average temperature after the CO2 doubling in 2100 from in the second "Report" published in l996 to . The assessment also notes that only about 50 to 90 per cent of this warming value will be achieved by 2100 due to the enormous thermal inertia of the oceans. Through this paragraph, we can see that the consequences of the greenhouse effect are not as serious as previously thought.

Let's say a farm has 1 farmer, 10 employees, and 500 head of cattle. Cows poop 5 bubbles a day, people poop 1 bubble people a day, with the frequency ratio of shit and fart is 1:5, 11 people fart 55 times a day, 500 cows fart 12500 times a day, with 20ml of fart gas per day, 11 people fart 1100ml a day, 500 cows fart 6250000ml a day, with 40% of greenhouse gases per ml of fart, 11 people emit 440ml of greenhouse gases per day, and 500 cows emit 250000ml of greenhouse gases per day.

Then take care of yourself.

The concept should be changed and the correctness of the greenhouse effect should be directly questioned.

Recognized issues like this have to be debated, and the person who wrote the question has a problem.
