Climate Change

1. Cause

a. Excessive Power Generation of Electricity and Heat

Generating electricity and heat by burning fossil fuels such as coal, oil and natural gas causes a large chunk of global emissions. Most electricity is still produced from fossil fuels; only about a quarter comes from wind, solar and other renewable sources.

b. Deforestation (Forest Cutting)

Cutting down forests to create farms or pastures, or for other reasons, causes emissions, since trees, when they are cut, release the carbon they have been storing. Since forests absorb carbon dioxide, destroying them also limits nature’s ability to keep emissions out of the atmosphere.

2. Effect

a. Unexpected Superstorm and Thunderstorm Weather

Lightning itself is also linked to variations in upper tropospheric water vapour, and tropospheric ozone, both of which are strong greenhouse gases. Climate model studies show that in a future warmer climate we may have fewer thunderstorms overall, but more intense thunderstorms, which may increase the amount of lightning by 10% for every one-degree global warming.

b. Global Warming

Nearly all land areas are seeing more hot days and heatwaves; 2020 was one of the hottest years on record. Higher temperatures increase heat-related illnesses and can make it more difficult to work and move around. Wildfires start more easily and spread more rapidly when conditions are hotter.

3. Action

a. Energy Conservation

Much of our electricity and heat is powered by coal, oil and gas. Use less energy by lowering your heating and cooling, switching to LED light bulbs and energy-efficient electric appliances, washing your laundry with cold water or hanging things to dry instead of using a dryer.

b. Reduction of Meat Consumption

Eating more vegetables, fruits, whole grains, legumes, nuts and seeds, and less meat and dairy, can significantly lower your environmental impact. Producing plant-based foods generally results in fewer greenhouse gas emissions and requires less energy, land and water.

Recount Text: Attack on Pearl Harbor

On 7 December 1941, Japan stroke the military base of Pearl Harbor. The base was owned by the US Navy. Their fleet harboured dozens of battleships and hundreds of aircraft. The assault began at 7:48 am Hawaiian Time. The base was indeed by Japanese aircraft and submarines. They bombarded torpedoes to all US battleships. Thousands of Americans were killed in the process. The US were suffering heavy casualties. On the other side, Japan received light casualties, with only a few shots sunk. After the attack, the Americans declared war against Japan, which led to World War II. USA President Roosevelt executed Order 9066 to all Japanese-Americans in America.

Holiday

My Holiday Last holiday, I went scouting with my team from DU SMS Pramuka SMAN 3 Bandung. I visited a few locations including Post Museum and Geology Museum. I officially became a permanent member for Scouts extracurricular. My team received badges and a walking bamboo stick as a gift from the Scout Leader. Later on, I went to my grandparents' house in Bandung to visit my big family. I slept over for two days. I played "Minecraft" with my cousins and siblings for the whole day. We built a gigantic Imperial Star Destroyer from "Star Wars" in my game. I also played "Pokemon" for the first time in forever. My favorite Pokemon was Charmander which eventually evolved into Charmaleon and finally Charizard. It had the element of fire. When New Year arrived, my family almost went to Jakarta but didn't go there. The reason was that flash floods were swarming the cities of Jakarta, plus the freaking traffic jam covered the public toll roads of C...
