Global Warming: Definition, Causes, Process, Impact, Solution
Global warming (global warming) or now better known as global climate change (climate change) is the warming of the earth's climate in general.
Increasing heat from year to year, makes some places in certain areas experience quite extreme changes.
Increasing global temperature is expected to cause other changes such as rising sea levels, changes in the amount and pattern of precipitation, and others.
Other consequences of global warming are the effect on agricultural yields, the extinction of various kinds of animals, and the loss of glaciers.

The cause of global warming
Global warming does not just happen, but happens because of several things that are done. Either from natural phenomena or from human actions themselves.
The following are the causes of the greenhouse effect:
1. Greenhouse Effect and Fossil Fuels
What is the greenhouse effect? The greenhouse effect is the process of increasing temperature on the earth's surface due to changes in the earth's atmosphere.
Sunlight that should be reflected into space, cannot be reflected perfectly so the light remains in the atmosphere.
2. Methane
The next cause of global warming is none other than methane gas. This cause mainly comes from livestock.
This is because according to the fact, compared to the oil industry, cattle farming produces more methane gas.
In fact, it has been proven that in the United States, as much as 20% of the methane gas that is produced is from belching and farts from livestock.
3. Global Climate Change
Global climate change also has great potential for warming. Even in addition, the impact of global climate change can be seen and observed directly on the local environment.
Say it like when a glacier melts, there is ice in the river, and the water flows faster.
In addition, the emergence of flora and fauna whose distribution is increasingly common and does not match the previously detailed data.
4. carbon dioxide
Excess carbon dioxide with its hot characteristics is also the main cause of global warming.
The causes of this amount of carbon dioxide are also very diverse and one of them is the burning of fossils.
This is evidenced by the state of America itself where even though it only has 4 percent of the world's pollution, it produces 25% of carbon dioxide because of the burning of fossils.
5. Heating Temperature
In this case, global warming is closely related to the name warming temperature. The impact of this large warming temperature is actually quite worrying.
Even recorded 600,000 deaths in the 1990s occurred due to natural disasters that are closely related to the weather itself.
In addition to causing death, this warming temperature can also be bad for those who suffer from certain diseases.
Global Warming Process
Global warming begins with sunlight shining on the earth.
The heat generated by the sun will be absorbed by the earth but only partially while what is not absorbed will be returned to the space (atmosphere).
but because in the atmosphere there are many gases that cause greenhouse effects such as sulfur dioxide gas SO2, carbon dioxide gas (CO2), and methane, water vapor and many more.
This causes the sun's heat cannot come out of the earth's surface and is trapped so that the sun's heat will bounce back to the earth. It happens continuously every day.
The more heat from the sun that enters the earth, the more gases that cannot be returned to the atmosphere cause the earth to be hotter. This is called global warming or global warming.
Global Warming Impact
The impact of global warming is of course very varied and touches various aspects of life. Here are some of the impacts that can occur:
- The melting of the ice caps. This caused sea levels at the North Pole to rise for the first time in hundreds of years. Even until the ship can pass through an area that was originally covered in ice.
- Harm the coral reef ecosystem.
- Sea level will rise by itself so that it can harm those living on the coast.
Global Warming Example
1. Uncertain change of seasons
The very fast change of seasons is one of the most visible effects of global warming.
Especially in subtropical and mountainous areas covered by snow. Every day the ice and snow melts faster because of the current heat of the earth.
2. Many new diseases
No less than 30 types of new diseases emerged from 1976 – 2008 which caused a nightmare for the world of health. Because curing one type of disease such as HIV and dengue is already difficult.
Logically, global warming makes the air temperature rise and makes mosquitoes more often mate with each other and produce more eggs. This accelerates the growth of mosquitoes.
3. Decreased agricultural production
The decline in agricultural production is one of the impacts of global warming because of the erratic seasonal changes and cannot be predicted exactly when it will come.
4. Animal lifestyle changes
Animals are also affected by global warming, because water sources dry up, making it more difficult for animals in these places to survive.
So they may decide to migrate to another place to live for their survival.
There have even been several examples that it is not uncommon for animals such as monkeys to choose to find food in resident villages.
5. Lots of dead plants
As happens in animals, as the temperature on earth increases and makes the water more dry, it will indirectly make many trees die.
How to Overcome Global Warming
Of course, this must be done together. Here are some ways that can be done to overcome global warming:
- Reducing the use of fossil energy.
- Reduce the use of vehicles that cause pollution.
- Switch to using environmentally friendly energy.
- Reduce tree cutting.
- Invest in eco-friendly products.
- Save electricity usage.
- etc.
Above has been explained about the impact, causes, processes, examples, and ways to overcome global warming (global warming).
