Carbon Dioxide - CO2
Sulphur dioxide (SO2) is a colourless gas with a characteristic smell that is readily soluble in water.
What is carbon dioxide?
Carbon dioxide (CO2) is a greenhouse gas emitted through human activities. Naturally, CO2 is present in the atmosphere as part of the Earth's carbon cycle. It helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. However, an increase in the CO2 concentrations in the atmosphere caused by human activities, is causing average global temperatures to rise, disrupting other aspects of Earth's climate. The main human activity that emits carbon dioxide is the combustion of fossil fuels for energy and transportation. Certain industrial processes and land-use changes also emit CO2.
What are the effects of carbon dioxide on the environment?
Extra carbon dioxide in the atmosphere increases the greenhouse effect. More thermal energy is trapped by the atmosphere, causing the planet to become warmer than it would be naturally. Extreme weather, food supply disruptions, and increased wildfires are other effects of climate change caused by greenhouse gases.
What carbon dioxide does with the health of humans?
While CO2 exposure has several benefits to plants and human life, too much carbon dioxide can affect your health negatively. That includes dizziness, headaches, restlessness, difficulty breathing, tiredness, convulsion, elevate blood pressure, and increased heart rate.
How can satellite data help with the carbon dioxide problem ?
Satellite data can show the concentration of carbondioxide in the air. It is also possible to map important carbon dioxide sources such as industires and traffic hot spots. Based on a monitoring system of carbon dioxide in a certain area, targeted policy decisions can be made to reduce emissions. Satellite data provides a good insight into risk areas and can also be used to test the effectiveness of measures.
