What Is Climate Change? / Section 1

From the last quarter of the 20th century to the present, i.e. 21. until the turn of the century, climate change was a highly publicized issue. This debate in the current situation, unfortunately, is always coherent in academic circles and among people who were engaged in research on the subject have not been conducted; the concept of climate change among the people nice unwarranted conspiracy theories, false rumors, and even pseudo-scientific arguments with yourself has established infrastructure, we are continuing to build. In many countries of the planet, especially the United States, the extent of such fallacies undermines the measures taken against climate change, which is now an enemy danger at the door, and also prevents the spread of consistent and durable information about it.

What Is Climate Change?

Climate change, as its name suggests, is a phrase that highlights the climatic changes that have occurred, especially in the last two centuries, and the factors that make up these changes. Various studies conducted in the past years, 19. it has repeatedly proved that since the end of the century, our planet’s surface has warmed dramatically.

The climate of the Earth has been constantly changing since the ancient existence of the planet. These changes are usually small differences in the Orbital of our planet from the sun made some nice changes to or living in, “climate change” under the name the collected information according to recent changes, unlike such differences, the atmosphere is getting hotter, and this also show that the rate of warming has risen. 10 of the past 13 years have been among the most intense years of this warming rate.

However, 97% of researchers agree that this increase in temperature in the atmosphere is caused by human activities, not by Orbital differences compared to previous variables or a situation created by the Sun.

Greenhouse effect and anthropogenic (human-caused) causes

Before moving on to the greenhouse effect, it is worth mentioning the Goldilocks principle first. The Goldilocks principle asserts to us that a phenomenon must conform to a certain distance, and that distance must also not be overdone. A popular example of this can be the location of our planet: according to the principle, Venus is the Earth and Mars, of these three planets sorted by their distance from the sun; extreme heat (Venus), extreme cold (Mars), and between these two standards is the Earth, which makes it “in full consistency”.

But as a reason why our planet is neither too hot nor too cold compared to these two planets, it would be as incomplete as it is wrong to point out only our distance from the Sun. Because it is not only the distance to The Sun, but also the thickness of the atmosphere that keeps our planet at a so-called “Full consistency” temperature!

The temperature of a planet, apart from its proximity to the star around which it circulates, is also linked to how effectively it can capture and hold the sun’s Rays up to the surface of the atmosphere. In other words, simply, the greater the thickness of the atmosphere, the hotter the surface of the planet is! In this case, you think, “Jupiter is a gas giant, so why is it so cold?”the question may come. But here it is necessary to consider that Jupiter is very far from the Sun. If there were two identical planets at equal distances to the sun, and the atmosphere of one was thicker, probably the planet whose atmosphere was thicker would be much warmer than the other. But this does not always have to be the case, sometimes the atmosphere can reflect the Rays back. Here we are interested in the atmospheric layer that causes the planet to heat up, a layer of atmosphere that takes the Rays in, but does not miss them out. That’s why it gets warmer inside. These layers are briefly called” greenhouse gases ” because they are the kind of gases that trap heat from the sun and various sources, just like a greenhouse.

Without further ado, we attribute this to our main topic: The Greenhouse Effect. A greenhouse effect is a kind of event that is inherently found in nature. In short, these greenhouse gases found in the Earth’s atmosphere are known as: water vapor (H2O), carbon dioxide (CO2), methane (CH4) and nitrogen (N2O), respectively. It absorbs charged particles from the sun, distributes them around it, and converts the energy in question into heat, allowing the atmosphere to heat up. This event is called the “greenhouse effect”. “Greenhouse effect”, a term first used in the 1800s, did not have any negative meaning, as it does now, when the effects that occurred in nature were studied. Until the 1950s, when climate change and its human-based factors were first encountered…

One of the main events that make this greenhouse effect dangerous, which is already present in nature, is the use of fossil fuels as energy, which is a human-based factor. Energy sources such as coal, oil and natural gas, carbon and methane gas (heat-trapping elements) are high in fuel rates and are processed for use as energy and released into the air, causing the surface of our planet to heat up. Such warming, on the other hand, brings with it various climatic hazards.

Decline of Arctic regions, rise of oceans and potential dangers of Nice

When it comes to climate change, there are two important factors that endanger many creatures, including our species: warming of the atmosphere and melting of glaciers in the Arctic regions. These two elements are directly related to each other and also help us understand why the nickname “global warming” is used when addressing climate change.

In the table above, you can see measurements of atmospheric temperature increases from 1880 to the present day made by four different institutes. The measurement shows that the temperature in the atmosphere has increased by 0.8 oC since the 1880s, as well as the 10 warmest years of the last 137 years experienced in the 2000s (except 1998). Such a temperature rate may not seem very much at first glance. But it is a change at a level that can lead to serious changes for the earth, whose ecosystem is very sensitive. One is the Arctic glaciers, which melt as a result of the warming atmosphere.

The most obvious danger that comes to mind when it comes to melting glaciers must be rising ocean levels. A very significant part of the settlements found in the Earth and, however, the population living in the settlements, are found in coastal areas. As sea and ocean levels rise, people living in these settlements, which are directly endangered, may have to cope with migration to the inner continents if they do not cope with the rising water levels over time. This situation not only triggers social crises that may occur, but also leaves us with the problem of bringing about economic difficulties due to trying to meet these migrations. Of course, this is perhaps the most obvious danger posed by melting glaciers, and other scenarios brought about by changes in the ocean can be more insidious and indirect than such coastal hazards. To better explain what we mean, it is worth knowing the proportions of water found on earth.

The proportion of fresh water found on our planet is around 2.5%. But only 1.2% of that 2.5 is found on the surface, in an accessible amount, and carries a life-supporting task. Of the remaining amount, 30.1% is groundwater resources, while 68.7% is glacial in Arctic areas. As the atmosphere warms, melting glaciers in fresh water, increases as it increases the melting glaciers, the enormous amount of fresh water in the ocean mixed with the salt water of the ocean, involved in its life puts you in serious danger. This, on the other hand, threatens to disrupt the balance known as the” thermohaline cycle”, which determines the connection of the dynamics of the Atlantic Ocean, especially with its salt ratio and density. (The fact that salt water is denser than fresh water, and especially with the melting of Greenland’s glaciers, the increase in the amount of fresh water in the northern oceans can cause this type of imbalance.)

Such a disorder endangers the food sources of various plankton lives, fish that feed on plankton, and ultimately people who make a living from fish. Similarly, the breakdown of the cycle also leads to a drop in the temperature of northern regions such as Europe, when the heatwave from tropical areas cannot reach the North; о severely affects agricultural harvests growing in regions and poses dangers that can lead to various economic and social crises similar to what we mentioned in the previous scenario.

Of course, only part of the dangers that may arise is covered by what we are talking about. Although there are no serious and long-term measures yet to help us avoid such dangers, various academic studies and the steps taken by nations against it are also a remarkable issue.
