The CO2 emissions they are one of the main causes of the greenhouse effect. Carbon dioxide, also called CO2 (carbon dioxide), released into the atmosphere by human activities, is linked to the use of fossil energy, namely oil, coal and natural gas. Others CO2 emissions are linked to deforestation phenomena and changes in the use of agricultural land.
Scientists from Hawaii's Mauna Loa Observatory announced that the levels of CO2 emissions atmosphere have reached a concentration of nearly 400 ppm (parts per million), a critical point of global warming at dangerous levels. The excess of CO2 emissions it is leading to a warmer world. According to Mariagrazia Midulla, WWF Italy's Climate and Energy Manager, "The last time that there was as much CO2 in the Earth's atmosphere as today, the world was 3-4 degrees Celsius warmer and the level of the warmest seas was 5 to 40 meters higher than today ". We are now close to the 400 PPM threshold of CO2, for the first time in human history.
A large slice of the CO2 emissions present in the atmosphere derive from the energy sector, in particular from fossil fuels. If the CO2 emissions should they continue to rise, one might expect to see record temperatures become the new summer standard. Not only scorching heat but above all drought, record storms and increasingly frequent floods.
“If CO2 levels continue to rise, it will become increasingly difficult and unlikely to adapt to climate change”Again Midulla affirms. To reduce the CO2 emissions a change of direction is needed, a global shift towards renewable energy and sustainable mobility. Each technology should be characterized by high energy efficiency so as to drastically reduce the CO2 emissions.
For Italy it is urgent to do its part, also in the national interest: "Those who move quickly and implement the energy change in a timely manner, redesigning the economy on a regenerative and highly efficient basis, will spend less and will be leaders in the next future. The new government must listen to the most enlightened scientists and economists, evading the influences of old lobbies that are condemning themselves and the country to the role of energy dinosaurs, instead of aiming for the future "concludes Midulla.
