Leading Contributors of Climate Change
Burning of Fossil Fuels
Burning fossil fuels releases significant amounts of carbon dioxide, and other, smaller amounts of methane and nitrous oxide into the atmosphere. These gases create a greenhouse affect by trapping heat in the troposphere, by reflecting it back into earth's surface.
Burning fossil fuels has created a lot of air and water pollution. The best way to fight greenhouse gasses is to switch to more sustainable fuel methods, such as, solar power, wind power, and nuclear power
Deforestation
Deforestation accelerates climate change, because Trees are needed to absorb carbon dioxide, and also because of reasons such as biodiversity loss, water cycle disruption, and soil erosion.
Roughly 10-20% of GHG emissions are caused from deforestation. The growing need for agriculture, with a rising population, causes much distress on many forest habitats globally. With this we lose a helpful defence mechanism in keeping carbon out of the atmosphere.
Agriculture
With a quickly rising population, the food demand has become a very great problem. Agriculture has been overused, and many GHG emissions have come from it. Agriculture is also an excuse to cause deforestation, which causes more GHG emissions, and is estimated to cause around 25-30% of GHG emissions globally.
Most of the GHG emissions caused by agriculture come from livestock, soil management, and land-use changes (deforestation).
Food Waste
Unwanted food is a great contributing factor to climate change, by wasting resources used in production (land, water, and energy) and releasing potent amounts of methane when it is decomposed into landfill.
Food waste accounts for approximately 8-10% of GHG emissions globally, and roughly one third of all food produced globally goes to waste.
Better planning, shopping, and storage, followed by creatively using leftovers and donating any surplus, are great ways to limit food waste, and moreover, global GHG emissions.
Volcanic Eruptions
Some of the substances that are released from volcanic eruptions include mainly water vapour, and more subtle amounts of carbon and sulphur dioxide. Although these volcanic gases actually block out a lot of sunlight and create a cooler temperature, some amounts of carbon dioxide, and other gases, can be released from volcanic clouds, and eventually find their way back up into the troposphere. This is because the gases eventually get far enough away from the large amount of water vapour to the point where it can completely separate.
