What Causes Climate Changes

climate change

Changes in the Earth’s climate can be attributed to the following factors: ocean currents, solar variations, volcanic eruptions, orbital changes of the earth and man-made activities.

The oceans are a significant part of Earth’s climate system. Interactions between the atmosphere and the oceans lead to the El Niño phenomenon which happens every two to six years. Also, changes in the circulation of the ocean could affect the climate by the movement of carbon dioxide out or into the atmosphere.

In a volcanic eruption, large amounts of gases (sulfur dioxide, dust, water vapour and ash released into the atmosphere could influence patterns in the climate for years. Volcanoes also produce aerosols that cause a cooling effect on Earth. Carbon dioxide, a greenhouse gas, is also produced by volcanoes. However, the amount of this gas produced by volcanoes is relatively insignificant when compared to the carbon dioxide that is produced by man.

The Earth is tilted at 23.5 degrees at right angles with its orbital path. Any change in the tilt angle, however small it may be, can cause changes in the climate pattern of the Earth. A large tilt results to colder winters and warmer summers. A small tilt results to milder winters and cooler summers.

Prolonged small changes in the sun’s output of energy can lead to climate changes. Scientific studies have shown that solar variations were responsible for the climatic changes in the previous years.

However, much of the cause of the Earth’s climate change in recent years can be attributed to man-made activities that create or generate greenhouse gasses, and not because of solar variations. Human activities such as fossil fuel combustion, deforestation and agriculture all release greenhouse gases that contribute to changes in the Earth’s climate.


Ways to Save Planet Earth

Here are some important ways to save planet earth from dangers:

1. Don’t throw your clothes away.
If the clothes are not still good, then give them to needy and poor people, or sell them to old shops. But do not throw them away.

2. Recycle the motor oil.
People use billions of Gallons of motor oil every year, whereas, nearly 350 million of gallons reaches in the atmosphere. This Motor oil can leak down into the ground Water supply lines. So before changing motor oil, take it to the gas station
That could recycle the oil.

3. Don’t put grease, pesticides, oil, antifreeze, and paints and other lethal domestic items down the pipelines or gutters because, these products reach finally into the rivers and oceans.

4. Avoid using the plastic shopping bags.
Do not Use the Plastic bags that can’t be recyclable, because they do not decay completely.
On the other hand the Paper bags are recyclable. Prefer paper bags instead of plastic bags.

5. Buy the products that can be recycled.

Such products help to preserve the natural resources and protecting the planet earth.

6. Buy the products free of CFC.

Chlorofluorocarbon (CFC) is very dangerous and can destroy the ozone layer, which gives cover to human beings from damaging UV rays. That could cause skin cancer and weaken immune system.
7. Purchase long-lasting products.
Buy the products, which are durable than disposables. For instance use metal razors
Than the disposable razors, That is to say Use the items that can be restored.

8. Make use of silver and metal dishes instead of the plastic or paper.
It would help to save planet earth and also save money.

9. Use the batteries that can be recharged.

The Batteries have heavy metals like Cadmium and mercury that is the main reason of pollution in the dumping areas. The heavy metals released in the air and pollute the environment.
