Scientists wanted to establish the total amount of carbon on the planet to find out how high the current carbon emissions into the atmosphere. They estimated the total number of carbon, which is on the surface and in the atmosphere of our planet, about 43.5 thousand gigatons. According to them, this is only 0.2% of the total carbon on Earth 1.85 billion gigatons, and 99.8% of the carbon is under the surface of the Earth.
Scientists have found out that volcanoes and other volcanically active education, such as cracks, released into the atmosphere by about 0.3-0.4 gigatons of carbon per year. Humanity thus emits carbon dioxide in 40-100 times more.
Scientists also believe that in the past was carbon catastrophe, for example, large volcanic eruptions, which resulted in the release of carbon into the atmosphere is approximately the same amounts, in our days.
Among such events, scientists have noted the fall of the meteorite that formed the crater Chikalovski 66 million years ago. According to their estimates, then the atmosphere separated from 425 thousand to 1.4 gigatonnes of carbon dioxide. But comparable stand volumes and in our days as a result of human activity.
“The volume of carbon dioxide allocated as a result of human activities over the last 10-12 years, equivalent to a catastrophic rise in the level of CO2 that happened in the past,” said Professor of Volcanology and Petrology at Cambridge Queens College Marie Edmonds.
Professor Celina Suarez from the University of Arkansas argues that the release of carbon dioxide is part of a natural cycle in the life of our planet, so the current levels of carbon in the atmosphere can be reduced in a natural way. But, according to her, it may take so long that humanity is already probably won’t make any difference.
In August, American meteorological society prepared a report which refers to the record amounts of greenhouse gases in the Earth’s atmosphere in 2018. They reported that in 2018 the volume of carbon dioxide, methane and nitrous oxide broke the record for all 60 years of observations.
In the fall of 2018 its report on climate change published by the United Nations. According to forecasts of experts, humanity left about 12 years to prevent the effects of global warming.
