Global Warming: Environmentalism
- The statistics paint a grim picture. According to the World Resources Institute, more than 80 percent of the Earth's natural forests already have been destroyed. Trees are natural consumers of carbon dioxide-one of the greenhouse gases whose build up in the atmosphere contributes to global warming.
- This problem affect globally where everyone has the responsibility to protect the environment.
- Global warming : when greenhouse gases (carbon dioxide, water vapour, nitrous oxide, and methane) trap heat and light from sun in the earth's atmosphere, which increases the temperature.
Problem statement
- The air pollution: from the car, illegal burning of rubbish
- Deforestation :cut down the trees for the new development of the country
- The earth heat up and the temperature increases.
- Variations in global climate in the last hundred years are significantly outside the natural range experienced in previous centuries
- Humanity’s emissions of carbon dioxide and other ‘greenhouse gases’ (GHG) are having a dangerous impact on global climate
- Polar bears and other Arctic and Antarctic wildlife are unable to adapt to anticipated local climate change effects, independent of the causes of those changes;
- The sea level rises at faster rate

- To create awareness to the world population.
- The temperature of the world increases tremendously
- " drawing information from the Middle Pliocene, an era about three million years ago when temperatures were 2 to 3 degrees C warmer and sea level was 25-35 meters higher than today’s level, Hansen et al. suggest that warming greater than 1 degrees C will constitute a “dangerous” level of warming."
- Air temperatures in the Antarctic Peninsula region have risen by over 2.5°C in the last 50 years, about 5 times faster than the global mean rate.
- To find solution to maintain the temperature : car pooling? more outdoor activities instead of playing computer games etc., turns off light when not using
- To protect the environment : animals, plants.
- To save the world for our future generations.

- Global Warming: The Origin and Nature of the Alleged Scientific Consensus
Richard S. Lindzen is the Alfred P. Sloan Professor of Meteorology at the Massachusetts Institute of Technology.
· Professor Richard review the problems in a very scientific way about the carbon dioxide significant increase (large population increases, doubling of carbon dioxide), further explained about the greenhouse effect (expecting a warming that from 0.5 degree centigrade to 1.2 degree centigrade)

- Nasa Giss: Research Feature Global Warming in the 21st Century: An Alternative Scenario
James Hansen et. al.
James suggest for the alternative to the reduction of non-CO2 GHGs (Greenhouse gases) and black carbon during the next 50 years. They found out that the global warming mainly caused by non-CO2 GHGs (Greenhouse gases). Carbon dioxide is the dominant climate change if its emission continue to increases. They comes out with an alternative scenario (carbon dioxide, methane, Chlorofluorocarbons, Tropospheric ozone and aerosols) to analyse the effect on the global warming.

- What are the solutions can we do as the residents on earth to reduce the global warming circumstance? (strict act/ law on deforestation, limit the electrical usage, tree planting)
- Are stronger punishment for those who involve on air pollution illegally?
- Should stronger limitations from government on cutting down the trees for the development of country?
