Is CO2 an environmental indicator?

1. INDICATOR (a) Name: Carbon dioxide (CO2) emissions. In addition to total emissions, sectoral CO2 emissions can be considered. The typical sectors for which CO2 emissions/removals are estimated are energy, industrial processes, agriculture, waste, and the sector of land use, land-use change and forestry (LULUCF).

Why is CO2 a good indicator of climate change?

Carbon dioxide (CO2) is an important heat-trapping (greenhouse) gas, which is released through human activities such as deforestation and burning fossil fuels, as well as natural processes such as respiration and volcanic eruptions.

What would happen if we stopped all CO2 emissions?

The energy that is held at the Earth by the increased carbon dioxide does more than heat the air. So even if carbon emissions stopped completely right now, as the oceans catch up with the atmosphere, the Earth’s temperature would rise about another 1.1F (0.6C). Scientists refer to this as committed warming.

Is CO2 sustainable?

Increasing co2 concentration is the key to sustainability by greatly increasing the rates of food and o2 production and natural cooling through endothermic photosynthesis.

How does increased CO2 affect the atmosphere?

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. This increase in the Earth’s temperature is called global warming .

Why are CO2 emissions a problem?

Carbon dioxide exists naturally as a trace gas in the Earth’s atmosphere. Carbon dioxide is a problem because it acts as a “greenhouse gas.” Due to its molecular structure, CO2 absorbs and emits infrared radiation, warming the Earth’s surface and the lower levels of the atmosphere.

What is a sustainable level of CO2 emissions?

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.
