When companies discuss sustainability Why is the focus on carbon dioxide co2 )?
Explanation: Typically, when businesses talk about sustainability, they emphasize carbon dioxide This is because "It is a greenhouse gas that is easily observable and remains in the atmosphere for generations."
It is essential for the survival of most living organisms and cycles in the ecosystem, through respiration (aerobic and anaerobic), photosynthesis, and combustion. Carbon dioxide plays an important role in the regulation of earth's temperature, and is one of the greenhouse gases.
To summarise, the most common stabilisation target is 550 ppm carbon dioxide. It is generally recognised that additional measures will be needed to reduce other non- CO2 greenhouse gases. If non-CO2 greenhouse gases are also included then the 'safe' target for carbon dioxide alone would have to be lower than 550 ppm.
Carbon dioxide is Earth's most important greenhouse gas: a gas that absorbs and radiates heat. Unlike oxygen or nitrogen (which make up most of our atmosphere), greenhouse gases absorb heat radiating from the Earth's surface and re-release it in all directions—including back toward Earth's surface.
Carbon dioxide (CO2) is a greenhouse gas. This means that it causes an effect like the glass in a greenhouse, trapping heat and warming up the inside. This effect is important: without the CO2 that naturally exists in the atmosphere, Earth might be too cold to support human life.
Carbon dioxide is an important greenhouse gas that helps to trap heat in our atmosphere. Without it, our planet would be inhospitably cold. However, an increase in CO2 concentrations in our atmosphere is causing average global temperatures to rise, disrupting other aspects of Earth's climate.
CO2 is an essential nutrient for land-based plants. The Earth's biosphere has also experienced a relative CO2 famine for many millennia—the recent increase in CO2 levels has thus had a measurable, positive effect on plant life.
The UNEP Emissions Gap Report 2021 estimates that total global emissions will need to fall to approximately 18 Gt CO2 (25 Gt CO2e) per year by 2030, on a pathway to net zero emissions by mid-century, in order to have a reasonable chance of limiting global heating to 1.5°C.
What is sustainability? Sustainability means meeting our own needs without compromising the ability of future generations to meet their own needs. In addition to natural resources, we also need social and economic resources.
There are both natural and human sources of carbon dioxide emissions. Natural sources include decomposition, ocean release and respiration. Human sources come from activities like cement production, deforestation as well as the burning of fossil fuels like coal, oil and natural gas.
Why does CO2 have such an important influence on our climate quizlet?
CO2 absorbs the longer wavelength radiation from the surface of the earth more readily than the shorter wavelength radiation from the sun. So CO2 in the atmosphere allows radiation to pass directly from the sun but absorbs some of the re-radiated energy from the earth.
When new life is formed, carbon forms key molecules like protein and DNA. It's also found in our atmosphere in the form of carbon dioxide or CO2. The carbon cycle is nature's way of reusing carbon atoms, which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over and over again.
How do consumers obtain the carbon that they need for their life processes? -They breathe it in from the surrounding air.
Carbon dioxide (CO2) comes from both natural sources (including volcanoes, the breath of animals and plant decay) and human sources (primarily the burning of fossils fuels like coal, oil and natural gas to generate energy).
The Short Answer:
The greenhouse effect is a process that occurs when gases in Earth's atmosphere trap the Sun's heat. This process makes Earth much warmer than it would be without an atmosphere. The greenhouse effect is one of the things that makes Earth a comfortable place to live.
