Global climate change refers to long-term changes in temperatures and weather patterns. Such shifts may occur naturally due to changes in the sun's activity or large volcanic eruptions. However, the 1800's From years to the present, primarily due to the burning of fossil fuels such as coal, oil and gas; the main driver of climate change as a result of human activities;
In addition, burning fossil fuels also causes greenhouse gas emissions. These act as a blanket that wraps around the Earth, trapping the sun's heat, and raising temperatures. In addition, the main greenhouse gases that cause climate differentiation include carbon dioxide and methane.
Additionally Clearing land and clearing forests can also release carbon dioxide. When the main sectors that cause greenhouse gases are examined, many places are seen. These include energy, industry, transportation, buildings, agriculture and land use.
What Causes Climate Change?
Causes of climate change is a very broad topic. The mechanics of the earth's climate system are simple. When energy from the sun reflects off the earth and returns to space, or when the earth's atmosphere releases energy, the planet cools. The planet heats up when the earth absorbs the sun's energy or when atmospheric gases prevent the earth's heat from radiating into space. Different elements, both natural and human, are a situation that can affect the global climate system.
The world has gone through phases of warming and cooling long before people were around in the past. Forces that can contribute to climate change include changes in the intensity of the sun, volcanic eruptions, and naturally occurring greenhouse gas concentrations.
However, records show that today's climatic warming, especially since the middle of the 20th century, is occurring much faster than ever before, and this is due to natural causes alone. It shows that it cannot be clicked.
Anthropogenic Causes of Climate Change
Greenhouse gas (GHG) emissions produced by human activities are the leading cause of the rapidly changing climate of the world today. Greenhouse gases play a crucial role in keeping the planet warm enough to live on. However, the amount of these gases in our atmosphere has increased rapidly in recent years.
The primary source of anthropogenic emissions is the use of fossil fuels such as coal, oil and gas for electricity, heat and transportation. A second major source is deforestation, which releases carbon that has been split into the air. tree cutting, tree cutting, fires and other forms of deforestation are estimated to release an average of 8.1 billion tons of carbon dioxide per year and account for more than 20 percent of all global CO2 emissions.
Other human activities that create air pollution include fertilizer, livestock production, and some industrial processes that release fluorinated gases. Although our planet's forests and oceans absorb greenhouse gases from the atmosphere through photosynthesis and other processes, these natural carbon sinks are not keeping pace with our increasing emissions.
The build-up of emerging greenhouse gases is causing alarmingly rapid warming around the world. It is estimated that the world's average temperature increased by about 1 degree Fahrenheit during the 20th century.
Impacts of Global Climate Change
So what are the effects of global climate change? As the earth's atmosphere warms, it collects more water, retains it, decreases it, and changes the air pattern. Apart from that, wet areas are wetter; makes dry areas drier. As a result of these, higher temperatures, storms, floods, heat waves and droughts are worse. and their frequency may increase.
These events can have devastating and costly consequences, endanger access to clean drinking water, fuel wildfires, damage property, cause hazardous material leaks, and pollute the air.< /p>
