Monograph: climate change (1)

This video and the following four are about the same topic: climate change.

Submitted by: About 19 years ago, the World Meteorological Organization and the United Nations created the IPCC organization when the problem of climate change was detected. A meeting of this international organization will begin tomorrow in Valencia.

For a week, the international experts who will meet in Valencia will talk about climate change. Although we haven’t heard much, we wanted to address climate change in today’s program. Welcome to Teknopolis.

There are still those who say that climate change is not happening, they say that the evolution of the climate is something cyclical and that human action has no effect. However, the scientific community as a whole considers the impact of human activity on climate change to be proven. And be it, it seems so, because the initial signs are becoming evidence.

There is no denying that this is a matter of great importance, as it will affect the way of life of all in one way or another. That’s why most of the time in today’s program is dedicated to climate change: we’re going to try to explain what it is, why it’s happening, how it’s affecting us and how it’s going to affect us, and we’re going to try to figure out if we’re in time to do something. If it were, it would be better.

To get into the subject, we thought about going to the base and answering a specific question: what is climate change?

Title: Climate change

We talk about the weather almost every day. And it's not surprising. The weather affects our minds, determines how we should dress, makes us feel the need to eat one thing or another, or makes us want to stay at home or go out on the street. Weather and climate are not the same thing. Weather is a daily occurrence, while climate is the dominant weather trend in a given area over a long period of time.

In the last century, the Earth's temperature has risen by an average of 0.6°C, while in Europe it has risen by 1°C. The 20th century has been the warmest century of the last thousand years. Looking ahead, it seems that the warming trend will be reinforced. Experts say that if things don’t change, by 2100, the temperature can rise to almost 6 degrees Celsius. That being said, the increase of 6 degrees Celsius does not seem very serious, but it must be taken into account that 11,500 years ago, during the last glaciation, when the whole of Europe was frozen, the temperature was, on average, 5 degrees lower than now. Not many are five degrees less, but enough to cause glaciation, so there is no need to be a magician to think that even five to six degrees more will have some effect.

So the climate is changing. And that’s not surprising, either, because climate change is nothing new. Throughout history, various natural phenomena, such as volcanic eruptions or fluctuations in solar radiation, have caused a change in the climate. However, these phenomena are not enough to explain the change that is taking place in such a short time.

Opinions by korte:

The experts are clear, we humans are to blame, because we produce the gases that cause the greenhouse effect. This is not entirely true, however, because there is an inherent greenhouse effect.

The sun is responsible for the natural greenhouse effect. The Sun heats up the Earth and as temperatures rise, the heat returns to the atmosphere in the form of infrared energy. The atmosphere, thanks to some greenhouse gases, absorbs this heat.
