My topic for this assignment is Global Warming / Climate Change.
Description
Global warming refers to the increased temperature of Earth's surface, including land, water and near-surface air.Per most of the scientific community, Earth has warmed significantly since the mid-20th century due to an increase in greenhouse gases that trap heat on Earth.
What is Global Warming?
Global warming is due to greenhouse gases such as carbon dioxide in the atmosphere increased dramatically absorbs terrestrial infrared long-wave radiation, thereby enabling the enhanced greenhouse effect caused. The reason is that a significant increase in carbon dioxide, one, people burning of fossil fuels (coal, oil, natural gas, etc.) emit large quantities of greenhouse gases; Second, deforestation, the reduced capacity of forests to absorb carbon dioxide. Since these greenhouse gases on the visible radiation from the sun is highly permeable, while the long-wave radiation reflected from the earth highly absorbent, eventually led to global warming.
Problem Statement & Issue
The atmosphere is a complex dynamic natural gaseous system that is essential to support life on planet Earth. Stratospheric ozone depletion due to air pollution has long been recognized as a threat to human health as well as to the Earth's ecosystems.
But nowadays, lot of people still don't save the air. It's effect the global warming pollution.
The global warming pollution reason example :
- Carbon dioxide emissions from fossil fuel burning power plants
- Carbon dioxide emissions from burning gasoline for transportation
- Methane emissions from animals, agriculture such as rice paddies, and from Arctic seabeds
- Deforestation, especially tropical forests for wood, pulp, and farmland
- Increase in usage of chemical fertilizers on croplands

Research Findings
Global warming not good for earth even for every living creature. Why nowadays the the global warming more serious? This is because every people always building their country to let it growth and get into future.
This is the effect global warming:
- Disappearance of coral reefs
- Widespread extinction of species
- Massive crop failures
- More killer storms
- Rise in sea levels worldwide
