What is CO2 emission and the greenhouse effect?
CO2 is a colorless, odorless gas composed of oxygen and carbon. Excessive emissions of this gas today are a major cause of global warming.
CO2 is a colorless, odorless gas composed of oxygen and carbon. Excessive emissions of this gas today are a major cause of global warming.Nowadays, CO2 emissions have multiplied and this has serious consequences on the planet, because this gas together with others such as methane and nitrous oxide contribute to global warming, that is to say these gases are part of what is known as greenhouse gases.CO2 is found in the atmosphere at an average ratio of 380 parts per million, in a cycle known as the carbon cycle, through which it is kept present in the atmosphere, biosphere, hydrosphere and lithosphere. Scientific research has shown that in the last 170 years the concentration of this gas in the atmosphere has increased, soaring from the last three decades reaching figures of 415 parts per million.Current statistics confirm that CO2 emissions have not decreased in recent years (except for the months of confinement due to the pandemic). CO2 emissions are mainly spread over five major sectors: transport (28%), industry (26%), electricity generation (23%), buildings (13%) and agriculture (12%).Scientists highlight that if CO2 emission levels are not reduced to the atmosphere, multiple risks and global impacts are expected for the Earth, which will bring catastrophic consequences. Such as crop collapse, decreased drinking water, sea level rise, disappearance of entire ecosystems, increased droughts, hurricanes and mass migrations due to climate changes.
