Global Warming

 Global warming is the increase in average global temperature in the atmosphere and oceans.

Around the planet Earth, there is a layer of gases that we call the atmosphere. The sun's rays pass through it, heating the surface of the Earth, which releases heat when heated. One part of that heat is absorbed by the atmosphere and the other part is lost in space. When the atmosphere absorbs this heat, it does not allow the Earth to cool too much and keeps the Earth's surface warm, enabling life on Earth. If it did not, the Earth would be very cold around -270 C, and it would be impossible to live here. We call this the greenhouse effect, a natural process.

Global warming is the process of changing the average global temperature of the atmosphere and oceans. The accumulation of high concentrations of greenhouse gases in the atmosphere blocks the heat emitted by the Sun and traps it to the Earth's surface, raising the Earth's average temperature.

The world is getting warmer. But is it a natural process on Earth or does it originate from human action? There is a lot of discussion about the subject, but it is always good to clarify it.

Despite its contribution to global warming, the greenhouse effect is a fundamental process for life on Earth, as it keeps the planet at livable temperatures. However, the significant increase in greenhouse gas emissions associated with natural events and actions triggered by human activity, such as deforestation, has been decisive for the system's energy balance imbalance, leading to greater energy retention and enhanced effects. Greenhouses, with reduced atmospheric warming and an increase in the average temperature of the planet. Global warming has become one of the biggest problems on Earth, the effects of which can be catastrophic, including direct health effects.

Thus, global warming is a process that results in an increase in the intensity of the greenhouse effect - radiation from sunlight reaches the Earth and is absorbed by the gases in the atmosphere, which infrared radiation to the Earth's surface. Start throwing back. Heat), increasing the temperature of the planet. Gases that interact with solar radiation that produce infrared radiation are called greenhouse gases or GHGs.

Cold will increase in some places

Despite the name "global warming", this phenomenon, the main cause of climate change, is responsible for causing episodes of extreme cold in some areas. This confuses many people. Including President Donald Trump, who thought that low temperatures in the United States in 2019 is evidence that global warming does not exist. The fact is that no such incident in the United States has been able to prove or disrupt the thesis of global warming. Globally, it is only possible to assess the hypothesis when analyzing the history of the Earth in geological time, which is very long.

An increase in greenhouse gas emissions increases energy retention in the oceans and atmosphere, increasing the intensity, frequency and impact of extreme weather, whether from cold or heat.

One phenomenon that changes with global warming is the thermocline circulation. These ocean currents, driven by differences in density due to the presence of salt, are responsible for bringing heat to some areas. With global warming and the melting of the polar ice cover, the salt concentration decreases, which may inhibit or slow down the thermo-alkaline circulation.

Thermoiline circulation caused by global warming may explain the decrease in temperature in some regions. Although an increase in overall global temperature, the absence of warm currents in naturally occurring regions will result in lower temperatures.

It does not mean luck. In a darker scenario, a drastic decrease in thermoeiline circulation may cause a substantial drop in temperature. If the recession continues, Europe and other regions that rely on thermo-mineral circulation to keep the climate warm and benign can expect an ice age.

What to do to help reduce global warming

Awareness and attitude change about global warming and climate change are very important. To contribute to reducing greenhouse gas emissions, first of all, it is necessary to know where these gases are.

1. Reduce car usage

Carbon dioxide, one of the main greenhouse gases, is mainly found in the burning of fossil fuels such as gasoline, diesel, and coal. To avoid this type of pollution, reducing intentional use of the car is a good way!

2. How to use bicycle, public or mass transport?

Bicycles are a good choice for short and long distance travel. Hitchhikers and quality public transport, especially trains and subways - which use renewable energy sources - are great options. When the location is very close, walking is also a good way.

3. The less CFC, the better

Although the consumption of CFCs (chlorofluorocarbons) in the country has been eliminated in a regulatory manner, refrigeration and air conditioning equipment operating on the basis of these harmful gases is still operational. Alternatively for CFCs, HCFCs (hydro chloro fluoro carbons) emerged, under the argument that they are 50% less destructive than the ozone layer. On the other hand, the new solution based on gases called fluoridized gases represents a major contribution to global warming. This is because this alternative technology can be thousands of times more harmful than carbon dioxide, which has pressurized the European Union into its restriction in favor of non-synthetic natural alternatives such as ammonia or carbon dioxide, which is the result of high cooling a quality.

     Finally, important steps that concern the political character of our lives in society are still to be taken. As a duty-bound and environmentally educated citizen, pressure brings together the logic and necessary conditions, in addition to making the best choices for representatives of governments, companies and society to make the best socio-environmentally viable decisions and postures, consequently , Combats global warming. . Examples of these actions are the ability to articulate in society, support for delegates who show concern with urban mobility, with global warming, and all other topics related to sustainability.
