The Causes of Climate Change
Deforestation
Positive signs
Despite this, there are some good signs.
Overall, the annual rate of net loss has slowed: from 0.18% in the 1990s to 0.08% (3.3 million hectares a year) from 2010 to 2015.
Many new laws have been put in place to try to reduce deforestation
Forests and trees store carbon. When they are destroyed, this carbon is released into the atmosphere
Deforestation contributes up to 10% of the carbon dioxide emissions caused by human activity, according to 2013 figures from the Intergovernmental Panel on Climate Change.
Tropical forests now emit more carbon than they capture, due to deforestation and degradation, according to a study published in 2017 using satellite data from 2003–14.
Burning of Fossil Fuels
The impact on the environment
The main reason that burning fossil fuels is bad is because when they are burned, they release large amounts of co2 into the air.
The economic revenue
Despite being terrible for the environment, the main reason that fossil fuels are used is because of their versatility, and the profit that they make. In 2020, which was a year in which the economy was hurting due to the coronavirus, the oil and gas industry in the us made about 110 Billion dollars.
A fossil fuel is a material formed underground from the remains of dead animals and plant and is extracted and burned for energy. The main fossil fuels are coal, petroleum and natural gas.
Natural Gas
The commercial sector uses natural gas to heat buildings and water, to operate refrigeration and cooling equipment, to cook, to dry clothes, and to provide outdoor lighting.
Petroleum
Petroleum products include transportation fuels, fuel oils for heating and electricity generation, asphalt and road oil, and feedstocks for making the chemicals, plastics, and synthetic materials that are in nearly everything we use.
Coal
Coal is not used nearly as much as it used to be, as it once was in every part of life, including transportation, residential and industrial. Now, it is primarily used as electricity
Livestock Farming
Animals
The two mains reasons why livestock is bad is because of the food required to sustain these animals and the amount of methane some animals release.
Livestock farming is responsible for 18 per cent of greenhouse gases such as methane and nitrous oxide.
Space
Farming livestock requires a huge amount of space, because after all, this is feeding most of the planet.
Livestock production accounts for 70 per cent of all agricultural land use and occupies 30 per cent of the planet's land surface.
Nearly sixteen percent of global freshwater, is devoted to growing livestock. Furthermore, a third of worldwide grain production is used to feed livestock.
Fertilizers
Fertilizers are used to grow the food, which is then used to feed the animals. These fertilizers are bad, as often fossil fuels are used to make them.
Roughly two percent of the world’s energy is used produce 100 million tons of artificial nitrogenous fertilizer per year to apply to high-energy crops like corn.
Fluorinated gases
Its affect on the Ozone layer
The main reason that fluorinated gases are used is because they do not damage the atmospheric ozone layer.
In fact, its main use is a substitute for ozone depleting substances.
GHG
Despite being used as a substitute for ozone depleting gases, it has 1 major drawback. It is an incredibly potent greenhouse gas (ghg), approximately 23 000 times stronger than co2.
The emissions of F-gases in the EU almost doubled from 1990 to 2014 – in contrast to emissions of all other greenhouse gases, which were reduced. However, thanks to EU legislation on fluorinated gases, F-gas emissions have been falling since 2015 (EEA data).
