Causes and effects of climate change

 

Causes and effects of climate change

 The whole world is suffering from climate change.  But to varying degrees, according to the United Nations website.

Fossil fuels – coal, oil and gas – are by far the largest contributor to global climate change, accounting for more than 75 percent of global greenhouse gas emissions and about 90 percent of all carbon dioxide emissions.

 Because they are in the Earth's atmosphere, greenhouse gas emissions trap the sun's heat.  This leads to global warming and climate change.  The world is currently warming faster than at any time in recorded history.  Over time, rising temperatures lead to changes in weather patterns and disruptions to nature's usual balance.  This poses many risks to humans and all other forms of life on Earth.

Causes and effects of climate change

 Power generation

 Generating electricity and heat by burning fossil fuels accounts for a large portion of global emissions.  Most electricity is still generated by burning coal, oil or gas, producing carbon dioxide and nitrous oxide – powerful greenhouse gases that blanket the Earth and trap the sun's heat.  Globally, just over a quarter of electricity comes from wind, solar and other renewable energy sources which, unlike fossil fuels, emit few greenhouse gases or pollutants into the air.

 Manufacture of goods

 Manufacturing and industry produce emissions, most of which come from burning fossil fuels to produce energy to make things like cement, iron and steel, electronics, plastics, clothing and other goods.  Mining and other industrial processes also release gases, as does the construction industry.  The machinery used in the manufacturing process often runs on coal, oil, or gas;  Some materials, such as plastics, are made from chemicals sourced from fossil fuels. Manufacturing industries are one of the largest contributors to greenhouse gas emissions worldwide.

 deforestation

 Cutting down forests to create farms or pastures, or for other reasons, causes emissions.  Because trees, when cut down, release the carbon they had stored.  Nearly 12 million hectares of forest are destroyed every year.  Because forests absorb carbon dioxide, their destruction also limits nature's ability to keep emissions out of the atmosphere.  Deforestation, along with agriculture and other land use changes, is responsible for nearly a quarter of global greenhouse gas emissions.

 Use of transportation

 Most cars, trucks, ships and planes run on fossil fuels, making transportation a major contributor to greenhouse gas emissions, especially carbon dioxide emissions.  Road vehicles account for the bulk of the combustion of petroleum-based products, such as gasoline, in internal combustion engines.

But emissions from ships and planes also continue to increase.  Transport is responsible for nearly a quarter of global energy-related carbon dioxide emissions.  Trends indicate a significant increase in energy use for transportation in the coming years.

 Food production

 Food production emits carbon dioxide, methane, and other greenhouse gases in various ways, including deforestation and clearing of land for agriculture and grazing, the digestive processes of cows and sheep, the production and use of fertilizers and manure to grow crops, and the use of energy to power farm equipment or fishing boats.  Typically using fossil fuels.  All of this makes food production a major contributor to climate change.  Greenhouse gas emissions also come from food packaging and distribution.

 Providing buildings with energy

 Globally, residential and commercial buildings consume more than half of our electricity.  As they continue to rely on coal, oil and natural gas for heating and cooling, they emit large amounts of greenhouse gases.  Growing energy demand for heating and cooling, with increased ownership of air conditioning, as well as increased electricity consumption for lighting, appliances and connected devices, have contributed to increased energy-related carbon dioxide emissions from buildings in recent years.

 Consuming a lot

 Your home and energy use, how you get around, what you eat and how much food you throw away all contribute to greenhouse gas emissions.  The same is true for the consumption of goods such as clothing, electronics and plastics.  A large portion of global greenhouse gas emissions are associated with private homes.  Our lifestyles have a profound impact on our planet.  The rich bear the greatest responsibility: the richest 1 percent of the world's population combined emit more greenhouse gases than the poorest 50 percent of the population.

 Therefore, replacing electricity generation with environmentally friendly methods has become a necessity.  The consumer comes to the idea of ​​choosing products from the factories that use them.  Clean methods of producing electricity that are environmentally friendly.  Such as generating electricity from solar or wind energy.  It is difficult to replace traditional methods of generating electricity, such as coal, oil and gas.  But reducing dependence on them has become necessary for this planet.  The spread of hurricanes, weather fluctuations, and floods affect agricultural production and plants.  Therefore, it is important for the consumer to be convinced that environmentally friendly products are one of the priorities of choice for his purchases.  To protect the planet he lives on from destruction.
