(ANSA) - ROME, AUGUST 09 - In 2019, atmospheric concentrations of Co2 were the highest in the last 2 million years and those of the main greenhouse gases (methane and nitrogen dioxide) the highest in the last 800,000 years; over the past 50 years, the Earth's temperature has risen at a rate unmatched in the past 2,000 years; mean sea level rise has grown at a rate not seen in the past 3,000 years. It is the latest alarm launched by the intergovernmental group of climate change scientists (IPCC) and contained in the first of three volumes - approved by the 195 UN countries and released today - of the Sixth Assessment Report which will be published in 2022.
The scholars, including three Italians from the CNR, affirm that climate change affects every area of the Earth and the entire climate system and warn that strong and constant reductions in CO2 emissions and other greenhouse gases are still possible and capable of limiting the disasters caused. from the climate changes we are witnessing in some parts of the world. The call is once again to the drastic and immediate cut in greenhouse gases to lower the fever of the planet, in particular of the CO2 which remains in the atmosphere for hundreds of years. During the shockdowns caused by the pandemic, in fact, despite the global reduction of 7% of carbon dioxide, there was no appreciable effect on the Earth's temperature.
