What is global warming? Global warming is the average temperature of Earth has increases since 1950 until now the temperature continuing increasing. Global warming can also refers to climate change that causes an increase in the average of temperature. However global warming are caused by natural events and human that are believed to be contribute to increase in average temperatures.
Causes of Global Warming
Global warming is a serious issue and is
not a single issue but a number of environmental issues. Global warming is a
rise in the surface temperature of the earth that has changed various life
forms on the earth. The issues that cause global warming are divided into two
categories include “natural” and “human influences” of global warming.
1) Natural Causes of Global Warming
The climate has continuously changing for
centuries. The global warming happens because the natural rotation of the sun
that changes the intensity of sunlight and moving closer to the earth.
Another cause of global warming is
greenhouse gases. Greenhouse gases are carbon monoxide and sulphur dioxide it
trap the solar heats rays and prevent it from escaping to the surface of the
earth. This has cause the temperature of the earth increase.
Volcanic eruptions are another issue that
causes global warming. For instance, a single volcanic eruption will release
amount of carbon dioxide and ash to the atmosphere. Once carbon dioxide
increase, the temperature of earth increase and greenhouse trap the solar
radiations in the earth.
Finally, methane is another issue that
causes global warming. Methane is also a greenhouse gas. Methane is more
effective in trapping heat in the atmosphere that carbon dioxide by 20 times.
Usually methane gas can release from many areas. For instance, it can be from
cattle, landfill, natural gas, petroleum systems, coal mining, mobile
explosion, or industrial waste process.

2) Human Influences on Global Warming
Human influence has been a very serious
issue now because human do not take care the earth. Human that cause global
warming are more than natural causes global warming. The earth has been
changing for many years until now it is still changing because of modern
lifestyle of human. Human activities include industrial production, burning
fossil fuel, mining, cattle rearing or deforestation.
First issue is industrial revolution. Industrial have been using fossil fuels for power machines. Everything that we
use is involved in fossil fuel. For example, when we buy a mobile phone, the
process of making mobile phone have involve machines and machines uses fossil
fuels, during the process carbon dioxide is releasing to the atmosphere.
Besides industrial, transportation such as cars is also releasing carbon
dioxide from exhaust.
Another issue is mining. During the
process of mining, the methane will trap below the earth. Besides, rearing
cattle will also cause methane because cattle released the form of manure.
However, cattle is important because it make the latter equally responsible for
the occurrence of global warming.
Next is the most common issue that is
deforestation. Deforestation is a human influence because human have been
cutting down trees to produce papers, wood, build houses or more. If human
continuing deforestation, carbon dioxide will concentrate in the atmosphere because
trees can absorb carbon dioxide from atmosphere. Besides, human also release
carbon dioxide when breathe. Therefore the amounts of millions of people breath
have release carbon dioxide to the atmosphere. If human continue deforestation,
human breathing that release carbon dioxide will stay at the atmosphere.

The Effect of Global Warming
The greenhouse gases will stay in the
atmosphere for many years since hundreds years ago. However, the effect that
global warming will cause on earth are extremely serious. There are many
effects that will happen in the future if global warming continues. That
includes polar ice caps melting, economic consequences, warmer waters and more
hurricanes, spread of diseases and earthquake.
First effect is polar ice caps melting. As
the temperature increase, the ice at the North Pole will melt. Once the ice
melt the first effect will be raise on sea levels because the melting glaciers
become oceans. According to the National Snow and Ice Data Center “if the ice
melted today the seas would rise about 230 feet”. It affects many low lying
areas such as the Netherlands. In future, the Netherlands will be cover by
water once the North Pole is melted. However, it is not going to happen so fast
but the sea level will continue rise.
Another effect is the species loss of
habitat. Species that include polar bears and tropical frogs will be extinct
due to climate change. Besides, various birds will migrate to other places
because animals are not like humans. They cannot adapt the habitat that changes
their living or temperature.
Next effect is more
hurricanes will occur and economic consequences still affect as well. Hurricane
causes damage to houses and government need to spend billions of dollars in
damage and people need places to stay or have been killed. Once a disaster
happens many people have died and diseases happen. Diseases are more serious
because it can spread to other people very fast and more people will get the
disease and the disease maybe come more serious because of different weather.
Solution
to Stop Global Warming
Now there are solutions that we can stop
global warming. However we human and governments need to move forward to
implement the global warming solutions. To reduce global warming we can do to
reduce the contribution of greenhouse gases to the atmosphere. Therefore, the
solutions that we can reduce global warming are reducing gasoline, electricity
and our activities that cause global warming.
To reduce gasoline mean we have a choice
to choose a hybrid car that reduce using gasoline. Besides, petrol price are
increasing. If a person everyday drives to work they need to pump petrol after
3 days and causes carbon dioxide. Another way to reduce gasoline is take public
transport or carpool to work. It can help reduce carbon dioxide and save cost.
Another way to reduce global warming is
recycle. Recycle can reduce garbage by reusing plastic bags, bottles, papers or
glass. For instance, when we buy foods, we can use our own containers instead
of plastic bags. Another example is after finish drinking the water from the
bottle; we can reuse it or use our own bottle. If all this is being reuse,
human can reduce deforestation and help save environment. Besides, turn off
electricity if unused. It can save thousands of carbon dioxide and buy product
that have energy saving because it saves cost and save environment.
Finally, human should stop open burning
such as burning dry leafs or burning garbage. It will release carbon dioxide
and toxic if burning garbage with plastic. Besides, government should reduce
deforestation because the earth temperatures are increasing. Trees will help to
improve the temperature on earth.
