Terrorism. What is it? It is the intentional use or threat to use violence against civilians and non-combatants "in order to achieve political goals". This tactic of political violence is intended to intimidate or cause terror for the purpose of "exerting pressure on decision making by state bodies.
Although terrorism is happening all around the world, I am not afraid of it. It is because, I know that Singapore is very vigilant and the government is taking a lot of safety measures to protect us.But although the government is taking safety measures, we as civilians should do our part to prevent terrorism from happening in Singapore. We can do so by looking out for suspicious behaviour in crowded places such as trains or buses. If we do spot such suspicious behaviour, we should immediately inform the bus captain or press the emergency button in a train. If we do this, Singapore will be safe from terrorism.

According to legend,
An Ethiopian goatherd skipped around after eating coffee cherries when he saw his goats doing the same. Coffee was a simple food and beverage for African tribesmen. Now, it is sold in large quantities worldwide. It is one of the top in value in trade. All coffee-exporting countries depend on coffee as the main income. Many people depend on it for their living. Many drink coffee a lot. In 1975, a frost killed almost half of Brazil’s coffee trees which changed the prices drastically. In 1979, frost hit Brazil again. Every tree lost result in no income for three to five years. The income loss is huge considering 15 million trees were lost. Brazil had to stop exporting coffee. Importers bought it in bulk afraid of shortage. Prices increased and farmers planted more. Coffee was abundant and prices fell. Farmers began planting other crops. Producers and consumers have limited production to what the market can absorb, have a reserve and sell at agreeable prices.

Reflective Summary
Over all, I have learnt many things on climate change. I have learnt what climate change is, the effects of climate change, what the greenhouse effect is about, what the government can do to reduce climate change and what we can do to reduce climate change.
Firstly, climate change is any long-term significant change in the expected patterns of average weather of a specific region over an appropriately significant period of time. The effects of climate change. Firstly, Sea level is rising and Ecosystems are changing. The greenhouse effect refers to the change in the steady state temperature of a planet by the presence of an atmosphere containing gas that absorbs and emits infrared radiation. The government has the energy efficiency campaign to raise the awareness of climate change every year. Also, the national target in the National Climate Change Strategy is to reduce carbon intensity to 25% below 1990 levels by 2012. We can do many things to reduce climate change such as using compact fluorescent light bulbs or we can walk or bike instead of driving a car which reduces the emission of fossil fuels into the atmosphere.
I have also learnt importance of reducing climate change. It is very vital for us to play our part in reducing the global problem we have. We can help by reducing, reusing, and recycling. We really have to do something or the future generation may not see things such as icebergs and polar bears.
My perspective has changed a lot as at first, I did not know that climate change was very serious but I do know now. Also, I thought at first that we could not do anything to stop climate change but after reading the five articles, I have learnt that we can play a big part in saving the earth.

In the end, I have learnt many things. Also, like I have mentioned before, it is very important for us to play our part in saving the world. We can help by destroying nature or other trees. In the future, we can plant trees so it will take in the carbon dioxide and give out oxygen.

From this article, I have learnt what we can do to reduce climate change. Firstly, we can travel light. We can either walk or bike instead of driving a car as cars run on fossil fuels, which release carbon dioxide into the atmosphere. Also, we can Teleconference instead of flying. For office meetings, if you can telephone or videoconference, you will save time, money, and carbon emissions from the airplanes. We can also check the light. Use compact fluorescent light bulbs. These energy-efficient bulbs help fight climate change because they reduce the amount of fossil fuels that utilities burn. Also, by Recycling and using recycled products, we can reduce climate change. Products made from recycled paper, glass, metal and plastic reduce carbon emissions because they use less energy to manufacture than products made from completely new materials.
Also, we can plant native trees as they absorb carbon dioxide from the air and use it as their energy source, producing oxygen for us to breathe. A tree in the temperate zone — found between the tropics and the polar circles—can remove and store 700 to 7,000 pounds of carbon over its lifetime. A tree that shades a house can reduce the energy required to run the air conditioner and save an additional 200 to 2,000 pounds of carbon over its lifetime. We can also turn down the heat. Turn down the heat or air conditioning when you leave the house or go to bed. You can easily install a programmable thermostat that can save up money and carbon. And finally, we can buy renewable energy. A growing number of utilities generate electricity from renewable energy sources with solar panels, windmills and other technologies.
Through this article, I hope that I can help to reduce climate change around the world. Also, I hope I can influence others to play their part in reducing climate change.

From this article, I have learnt what the Singapore government is doing to stop climate change. It has the energy efficiency campaign to raise the awareness of climate change every year. Also, the national target in the National Climate Change Strategy is to reduce carbon intensity to 25% below 1990 levels by 2012. A reduction in carbon intensity (carbon dioxide emissions per dollar of GDP) does not necessary mean a reduction in the amount of carbon emissions. The problem of climate change is one of absolute concentrations of carbon dioxide and each country must reduce its absolute carbon emissions. The government plays its part by also coming up with the Singapore Green Plan (SGP). The SGP2012 is Singapore’s 10-year blueprint towards environmental sustainability. More than 17,000 participated in the review through various platforms. It has brought out key environmental issues like Climate Change and resulted in a robust plan able to address emerging environmental challenges.
The SGP2012 has incorporated the majority (more than 90%) of the recommendations raised by the three Focus Groups formed as part of the review, reflecting strong public ownership and commitment to continue to protect and enhance our environment. The SGP2012 covers six focus areas - Air and Climate Change, Water, Waste Management, Nature, Public Health and International Environmental Relations. The air and climate change is to raise public awareness on energy efficiency and climate change.
By reading this article, I hope I can understand that the government is doing something to stop climate change in Singapore as all the while; I had the misconception that the government was not doing anything about it.

From this article, I have learnt all about the green house effect. It refers to the change in the steady state temperature of a planet by the presence of an atmosphere containing gas that absorbs and emits infrared radiation. Greenhouse gases, which include water vapor, carbon dioxide and methane, warm the atmosphere by efficiently absorbing thermal infrared radiation emitted by the Earth’s surface, by the atmosphere itself, and by clouds. As a result of its warmth, the atmosphere also radiates thermal infrared in all directions, including downward to the Earth’s surface. Thus, greenhouse gases trap heat within the surface-troposphere system.
I have also learnt many new facts from this website. I have learnt that in the absence of the greenhouse effect in an atmosphere, the Earth's average surface temperature of 14 °C (57 °F) could be as low as −18 °C (−0.4 °F), the black body temperature of the Earth. I have also learnt that the greenhouse effect is one of several factors that affect the temperature of the Earth. And finally, I have learnt that in our solar system, Mars, Venus, and the moon Titan also exhibit greenhouse effects according to their respective environments. In addition, Titan has an anti-greenhouse effect. The anti-greenhouse effect is a neologism used to describe two different effects, coming under the header of "the cooling effect an atmosphere has on the ambient temperature of the planet." Unlike the greenhouse effect, which is common, an anti-greenhouse effect is only known to exist in one situation in the Solar System, as well as another which is a misnomer.
Through this article, I have about the greenhouse effect and the anti-greenhouse effect. I hope that I can do my part in saving the world by not contributing to climate change.

From this article, I have learnt what the effects of climate change are. Firstly, Sea level is rising. During the 20th century, sea level rose about 15 cm (6 inches) due to melting glaciers and expansion of warmer seawater. It could rise much more than that in the next 100 years. Arctic sea ice is melting. The summer thickness of sea ice is about half of what it was in 1950. This is causing the Arctic to warm up faster.
Also, Ecosystems are changing. As temperatures warm, animals and plants may either look for a cooler place to live or die. Species that are vulnerable include endangered species, coral reefs, and polar animals. Warming has also caused changes in the timing of spring events and the length of the growing season. Hurricanes have changed in frequency and strength. There is evidence that the number of intense hurricanes has increased in the Atlantic since 1970. Scientists continue to study whether climate is the cause.
Also, heat waves more frequent. It is likely that heat waves have become more common in more areas of the world. Seawater is becoming more acidic. When carbon dioxide, a greenhouse gas, gets into the oceans, it makes the water more acidic. This could impact coral reefs and other marine life.
