Climate Change

Climate change is a long term change in the Earth’s climate, especially a change due to an increase in the average atmospheric temperature.

This is how climate change looks

like!

Conditions when the effects of materials are harmful

Many attempts to save the world from global warming by removing carbon dioxide from the atmosphere but other factories continue burning fossil fuels that is why they can’t prevent the ocean from dying as a result of a build-up of acidity.

GLOBAL WARMING AND GREENHOUSE EFFECT

When fires like this happen, the burning trees releases excessive amount of carbon dioxide into the air. Large amount of this gas prevent heat reflected to Earth from escaping into the outer space. This phenomenon is called greenhouse effect.

GLOBAL WARMING AND GREENHOUSE EFFECT

It traps heat from the environment. It causes air temperature to rise. This condition results in the abnormal rise of the Earth’s temperature popular known as global warming.

ACID RAIN FORMATION

When fuels such as firewood and gasoline used in motor are burned, CO2, sulfur oxide and nitrous oxide are released into the air. Combined with water vapor, these gases form acid solution, known as acid rain.

ACID RAIN FORMATION

Acid rain can corrode stone buildings and status made of limestone or calcium carbonate. Acid rain also washes away top soil and reduces the production of crops. Being harmful, it can also contaminate rivers, dams and water.

THINNING OF OZONE LAYER

The ozone layer protects the Earth from the harmful effects of sun’s ultraviolet rays. The thinning of ozone layer is caused by chlorofluorocarbons or CFC’s.
