:warning: Factors that contribute to climate change :warning:
Burning Fossil Fuels
We release around 50 billion tonnes of greenhouse gases each year. Greenhouse gasses include Carbon Dioxide, Methane and Nitrous Oxide
Releases Carbon Dioxide by burning fossil fuels and extracting the fossil fuels through gas powered machinery. Most common gas when burning fossil fuels.
Releases Methane through extracting the fossil fuels and burning fossil fules. Released through open mines, oil mines, and pipelines. This is called fugitive emissions
Releases Nitrous Oxide through the burning of fossil fuels.
Greenhouse effect
Greenhouse effect is created mainly through Methane, Carbon Dioxide, Water Vapour and Nitrous oxide. The Greenhouse creates a thin layer in the troposphere, trapping heat in the earth. This is why it's not freezing at night, and it's warmer during the day! Without the Greenhouse effect, the avg. temp on earth would be -18 degrees on earth
More greenhouse gasses means more heat trapped in atmosphere, causing earth to warm up
Melts icebergs, can cause Earth to heat up due to lower albedo and also creating more fresh water affecting Thermohaline circulation
Causes earth to warm up, creating warmer climates. This can effect the weather system
Greenhouse gasses
Carbon Dioxide (CO2) accounts for 79.7% of greenhouse gases. CO2 exists naturally in the atmosphere.
Methane (CH4) accounts for 11.1% of greenhouse gasses. Methane is more effective than CO2. One pound of CH4 has 28 times the global warming potential as one pound of CO2.
Nitrous Oxide (N2O) accounts for 6.1% of greenhouse gasses. N2O global warming potential is 265 times greater than that of CO2 over a 100-year period.
Fossil fuels are responsible for approximatly 68% of global greenhouse gas emissions.
Deforestation
Approximately 10 million hectares of forest are destroyed each year. Forests are responsible for removing around 16 billion tonnes of CO2 per year. Deforestation, together with agriculture and other land use changes, is responsible for roughly 11-20% of global greenhouse gas emissions.
Tree's and plants in the forest have to photosynthesis, using carbon dioxide as one of their resources. Forest absorb carbon dioxide out of the atmosphere in exchange for oxygen and glucose. Tree's also cool down regions by releasing moisture
By cutting down tree's and destroying forests, this releases around 8.1 billion metric tons of CO2 into the atmosphere since tree's store CO2. This contributes to the greenhouse gasses effect. Also, by cutting down tree's this will make land drier since tree's release moisture into the climate.
Agriculture and Livestock
Livestock are a significant source of methane emissions. Combined with deforistation, Agriculture and Livestock are responsible for around 11-20 % of all greenhouse gas emissions
Methane and nitrous oxide are released into the atmosphere when the animals burp or fart, and it’s also contained in their urine and manure. Also release CO2 through Cellular respiration
One cow can produce up to 264 pounds of methane every year
Farm animals produce around 450 million tons of manure every year. When manure is stored in an environment with insufficient oxygen, it releases nitrous oxide and methane into the air as a result.
Synthetic fertilizers release Nitrous Oxide into the atmosphere. It's even more powerful when excess fertilizer washes into the soil.
Transportation
Transportation accounts for 1/4 of global energy-related CO2 emissions.
Most vehicles run on fossil fules contributing to CO2 emmisions
By building roads, people have to make space, destroying forests in the process
Cars are responsible for 40% of CO2 emmisions
Volcanic Euruption
When a volcano erupts, they release CO2, CH4, sulphur dioxid and many other gases.
Ash causes the earth to cool down since it's blocking the sun. This effect lasts for around 1-3 years
Sulphur dioxide converts into sulfuric acid in the atmosphere, forming fine sulfate aerosols that reflect sunlight, causing global cooling. This is a temporary effect
Volcanic carbon dioxide and methane has the potential to promote global warming.
