Major fossil fuels include oil, coal and natural gas. This produces a large amount of energy needed for human activities. This energy is used for industries,transport, domestic/commercial activities. Due to their high carbon content, they contribute to the increase of greenhouse gas in the atmosphere when burned

An increasing number of people live in urban areas such as cities and towns. Large amounts of fossil fuels are burnt to provide energy for household activities in urban areas (eg. lighting, air-conditioning). Transportation in urban areas also contributes to the amount of greenhouse gases because there is a separation from home life and work life. Driving to work in cars leads to air pollution.]]> 2018-02-23 02:31:11 UTC https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234557061 Clarisse clarisse_faye_tan_en_min_2020 https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234557078 deforestation results in a decreased amount of trees. Trees are our store of carbon. There will be less trees to take in the carbon dioxide in the atmosphere. Furthermore, the carbon dioxide that was stored in the trees would be released into the atmosphere as the trees are deforested. Even more carbon dioxide would be produced as the trees are burnt, increasing the rate of combustion which will produce more carbon dioxide. The increased amount of carbon dioxide will contribute to the enhanced greenhouse effect and climate change will be more severe.]]> 2018-02-23 02:31:22 UTC https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234557078 natania_leow_en_qi_2020 https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234557081 The use of inorganic fertilisers increases the amount of nitrous oxide in soil]]> 2018-02-23 02:31:23 UTC https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234557081 Sheralyn Tan https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234557111 Increase of cars causes climate change. When fossil fuels like petrol or diesel are burned they give off carbon dioxide - the main climate change gas. The amount of carbon dioxide given off is directly related to the amount of fuel burnt. Heavy cars with big engines use a lot of fuel per distance travelled, releasing more CO2 and worsening climate change. Collectively, cars and trucks account for nearly one-fifth of all US emissions, emitting around 24 pounds of carbon dioxide and other global-warming gases for every gallon of gas.]]> 2018-02-23 02:31:31 UTC https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234557111 Tricia Lee lee_rui_qi_tricia_2020 https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234557121 One cause of climate change is through air pollution.

- carbon dioxide (greenhouse gas) is released --> it traps heat in the atmosphere, increasing the global temperature, leading to climate change

The burning of fossil fuels. Fossil fuels have a high carbon content and produce large amounts of carbon dioxide when burnt.

2. Deforestation
Forests absorb billions of tonnes of carbon dioxide yearly via photosynthesis. There are fewer trees and other plants to take in carbon dioxide each year due to deforestation. When trees are cut down, a lot of carbon dioxide is also released into the atmosphere, contributing to global warming.

3. Agriculture
Cattle farming contributes to global warming as millions of tonnes of methane are released each year as waste gas from cattle farming. 
Tractors run on fossil fuels which release carbon dioxide. Inorganic fertilisers increase the amount of nitrous oxide in soil and the nitrous oxide released into the atmosphere when the rain flows through the soil or when the soil is ploughed. Organic matter such as dead leaves and manure release methane during decomposition.
4. Urbanisation
Large amounts of fossil fuels are burnt to provide energy for household activities such as heatng, cooking,

There are 2 types of farming subsistence and commercial farming. However it is commercial farming that is majorly contributing to climate change. The main purpose of the farm is to sell and the crops grown there is called cash crops. The farms are large scale and are usually called plantations. For example, cattle ranching accounts for 80% of deforestation in Amazon Basin.  Soya bean farming also takes 242 000 km in Amazon Basin.]]> 2018-02-23 02:41:01 UTC https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234558410 Jolene https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/234558688 Deforestation contributes to climate change.

The cutting down of forests is a major cause in climate change.It impacts it in 2 ways.Firstly,the process of cutting down trees releases the carbon stored in the trees. Furthermore,most methods of deforestation is through burning,which is also releases much carbon dioxide into the atmosphere,as well. Secondly,trees help to regulate the climate by absorbing CO2 from the atmosphere. So when they are cut down, that beneficial effect is lost and the ,adding to the greenhouse effect.

Deforestation causes trees, which store carbon dioxide within them, to die, releasing the carbon dioxide. Additionally, this prevents the trees from taking in carbon dioxide in the future.

The increased amount of carbon dioxide trap an increased amount of heat due to longwave radiation. This causes the earth to heat up exponentially, and the climate of many places to swiftly change.

Therefore, global warming and climate change are caused by deforestation.

An example of such an activity would be burning of fossil fuels.

Fossil fuels are hydrocarbons, primarily coal, fuel oil or natural gas, formed from the remains of dead plants and animals.

When fossil fuels are burnt to create electricity, power our cars or modern appliances,  it emits  toxins and global warming emissions into the atmosphere.

Natural gas’s climate emissions are not only generated when it’s burned as a fuel at power plants or in our homes. The full global warming impact of natural gas also includes methane emissions from drilling wells and pipeline transportation.

Methane, the main component of natural gas, is a much more potent greenhouse gas than carbon dioxide—some 34 times more effective at trapping heat over a 100-year timescale and 86 times more effective over a 20-year timescale. 

Preliminary studies and field measurements show that these so-called “fugitive” emissions range from 1 to 9 percent of total natural gas lifecycle emissions. Methane losses must be kept below 3.2 percent for natural gas power plants to have lower lifecycle greenhouse gas emissions than coal.

Oil drilling can also produce methane. Although it can be captured and used as an energy source, the gas is often either released or burned. Released methane contributes greatly to global warming, and poses a serious safety hazard. Flaring the gas converts it from methane to carbon dioxide, which reduces its impact but still releases additional greenhouse gases to into the atmosphere. The World Bank estimates that 5.3 trillion cubic feet of natural gas, the equivalent of 25 percent of total US consumption, is flared annually worldwide, generating some 400 million tons of unnecessary carbon dioxide emissions [18].

Australians are big producers of CO2 pollution compared to the rest of the world. The level of CO2 pollution per person is nearly double the average of other developed nations and more than four times the world average.

Electricity generation is the main cause of carbon pollution in Australia because 73% of their electricity comes from burning coal and 13% from burning gas . The remaining 14% comes from renewable energy sources like hydro, solar and wind, which do not emit carbon pollution . 

Reducing the amount of electricity generated from coal and gas, and increasing the amount of electricity from clean, renewable energy sources like solar and wind, means less carbon pollution is emitted. This is one of the main ways we can address global warming.]]> 2018-03-01 12:31:09 UTC https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/236860332 Louise https://padlet.com/yuhanna_mohammad_isham_2020/ebm18xriuxu/wish/237258667 When trees are cut down, the amount of carbon dioxide in the air increases, as there are less trees to take in carbon dioxide during photosynthesis.
