Non-Climatic Factors Causing Climate Change

 

Climate change refers to changes over time in the earth's global climate or in regional climates. This identifies shifts in volatility or average weather conditions or average time scales of (normal) weather that fluctuate over decades and millions of years.

These changes may be due to internal processes on Earth or external factors (for example, sunlight intensity fluctuations) or, more recently, to activities related to climate change. Particularly in recent applications, the word 'climate change' sometimes refers only to the latest changes in the new climate in the field of environmental policy.

One of the problems of human technology is the problem of climate change and its possible impact on different economic and social sectors. Latest reports indicate that greenhouse gas emissions are a significant cause of global warming. In understanding the Earth's climate history, greenhouse gases also play a significant role. The effect of greenhouse gases, which produce heat by trapping greenhouse gas heat, plays a key role in controlling the temperature of the earth, according to these studies.

                   

Introduction

 

Over time, climate change refers to changes in the global climate of the World or in regional climates. It explains variations in variability or average weather conditions on time scales that fluctuate between decades and millions of years - or moderate (conventional) climates. These changes may be due to internal processes on Earth or external factors (such as variations in sunlight intensity) or, more recently, to activities related to climate change. Especially in recent applications,

Climate Change Factors

 

Climate change is due to fluctuations in the atmosphere of the earth, natural processes around it, and the effect on it of human activity. Climate forces are also referred to as external influences that can shape the climate, including processes such as solar radiation variations, earth rotation (position) and greenhouse gas concentration (concentration).

Ocean Volatility

 

Climate change can also result from shifts in ocean processes on a nearly decade-long scale. The Pacific Decadence, the North Atlantic Oscillation, and the Arctic Ocean Oscillation, which are considered to be unique conditions within the climate system, comprise many of the climatic conditions, most especially the South Oscillation, at least because of their presence. Heat has been stored in the oceans to some degree and transported in a number of ways between various sources. Longer t On

Climatic Memory

 

In the sense that the current state of the environment not only represents its inputs, but also the history of how it originated and reached this level, most types of fluctuation within a climate system can be regarded as waste. For example, lakes can be destroyed by a decade of drought, deserts can dry up completely and deserts can grow. Instead, in recent years, such conditions could lead to less rainfall. In short, because various aspects of the atmosphere, climate change can be a constant random proces

 

Non-climatic Factors Causing Climate Change

Greenhouse Gases

 

Latest studies have shown that emissions of greenhouse gases are a significant cause of global warming. In understanding the Earth's climate history, greenhouse gases also play a significant role[10]. The greenhouse effect produced by heat trapped by greenhouse gases plays a key role in controlling the temperature of the earth, according to these studies.

Carbon dioxide levels have probably ranged from more than 5,000 ppm to less than 200 ppm over the last 600 million years, primarily because of the impact of geological processes and biological innovations. More carefully, it has been argued that pollution variations of tens of millions of tons per year do not correspond well with climate change, which is likely to play a more prominent position in plate tectonics. There are, however, several examples of rapid increases in the amount of greenhouse gases in the atmosphere of the Planet that tend to be closely related to extreme warming, including the maximum period of the Paleocene-Eocene (Paleocene-Eocene).

Permian-Trasic extinction in the Scandinavian (Varangian) area, reptile and dinosaur extinction and the end of the glacial phase of the Earth. Since the 1950s, rising levels of carbon dioxide have been a significant factor in global warming during the modern period.

                                          

What are the consequences of global warming?

The climate is influenced both by the temperature and the amount of snow and rain. The latitude, altitude and ocean currents in that area also influence temperatures and rainfall in each region.

Climate change is a phenomenon that affects the climate of each country by altering the impact of the above influences, leaving adverse effects. Some of the established effects of climate change are

 

·     Increasing sea levels and decreasing resources of freshwater

 

·        In the high latitudes and the Northern Hemisphere, regional  climate change.         

·        Change in rainfall and wind direction.

·        Natural disasters, such as hurricanes, tornadoes and flooding, have increased.

 

·        Increasing the drought rate and developing areas in the desert.

 

·        Increased air pollution because of increased hot winds in some regions.

 

·        Possible effects on the transmission of diseases such as           

           

 

Characteristics of Recent Climate Change

Human Impacts on Climate

Human influences are actions by which humans alter the atmosphere and influence the ecosystem. The key current concern is the rise in 2CO levels due to the emissions of fossil fuel combustion, resulting in aerosols (atmospheric cooling particles) exerting a cooling effect (on climate). The climate is also affected by other factors, including land use, ozone depletion and deforestation.

Fossil Fuels

Land Use

Prior to the widespread use of fossil fuels, land use was undoubtedly the cause for the greatest human influence on the local environment. The climate is profoundly changed by irrigation, deforestation, and cultivation. They can, for example, alter the amount of water entering and leaving a specific location. By affecting the cover of the planet and changing the amount of sunlight it receives, they may also alter the reflection of the earth. The climate of Greece and other Mediterranean countries is stated to be steadily due to the deforestation between 700 BC and AD (the wood of these forests was used to build ships

 As a result, the region's modern climate has become hotter and drier for the most half, and the tree species used in ancient times to build ships are no longer found in the area. Controversial Hypothesis of William Rodiman The early anthropogenic hypothesis states that over the past 8,000-5,000 years, the increasing in agriculture, along with deforestation, increased methane and carbon dioxide.According to the Rodiman hypothesis, these increases, which go back to previous degradations, may be responsible for the delay in the start of the next glacial period.

Water resources

Several studies have been performed using hydro-meteorological data and runoff models that have been combined with diffusion scenarios and temperature changes to examine the impact of global warming on Iran's water supplies. The results of periodic runoff data obtained from 398 hydrometric stations indicate that 47 percent of them have altered the flood index.Moreover, in the 600 meteorological stations analyzed during the years 1990-2000, climate change was clearly observed.

For 30 river basins, the long-run runoff model used indicates that the rise in temperature raises the amount of runoff in winter due to the conversion of snow into rain and due to the rapid melting of snow in the spring. Increasing temperatures have also been shown to affect runoff in catchment areas and reduce variability in runoff due to rainfall.

Agriculture:

Increased climate-change temperatures can decrease the fertility of rice seedlings, decrease the shelf life of maize, decrease the immaturity of wheat and decrease the germination of potatoes. On the other hand, climate change decreases wheat and cotton production by decreasing the quantity and timing of rainfall, according to historical evidence. Thus, recent droughts reduced 1,050,000 tons of irrigated wheat and 2,543,000 tons of dry wheat in the period 1998-1998. These findings have shown that Iran's agricultural sector is very susceptible to the climate change phenomenon.

Forest and Land Use

There is a serious impact of global warming on the forest market. Examples of these effects are the change in the natural growth of forest plant species, especially resistant species, and the extinction of semi-resistant species. The normal growth of disturbed forest plants results in a decline in the production of wood and non-wood products in the forest. Land erosion, especially in arid and semi-arid regions, can be exacerbated by invasion of forests and pastures and exacerbation of plant diseases. Rising water levels are killing mangrove marine forests in the Persian Gulf and the Sea of Oman. The environmental conditions for wildlife in woodland areas are rapidly unfavorable due to the decline in the amount of forage in forests, which in some cases may be a sign of the beginning of desertification. Growing temperatures and droughts are killing vegetation and thus accelerating soil erosion, which eventually has adverse social effects, such as migration, due to the deterioration of the ecological potential of the region due to these degradations Comparing the Iranian situation. But this has come as a surprise to many, considering the environmental situation in Iran in recent years.Recently, Yale University in the United States released a study showing the improvement of Iran's environmental condition, but some experts claim that the country should not be included in these statistics for some reason. Iran is ranked 68th out of 180 countries in the Environmental Performance Index or EPI 2020 survey, released by Yale University, USA, and has a score of 477 out of 180 countries (out of 100). The condition of countries like Turkey, Egypt, China, Qatar, Saudi Arabia, etc. In this list, it is worse than Iran. Also, the highest environmental performance was obtained by countries such as Denmark, Luxembourg, Switzerland, Britain, France, and Austria. In previous times, Iran has recorded changes in the country's environmental efficiency, and over the past decade, Iran's index has risen 9.1 points. But this has come as a surprise to many, considering the environmental situation in Iran in recent years.
