The Crazy Scale of Human Carbon Emissions



Current data (from direct measurements of the atmosphere to historical records of industry) tells us that between 1751 and 1987 fossil fuels put about 737 billion tons of CO2 into the atmosphere.
Between just 1987 and 2014 it was about the same mass: 743 billion tons. Total CO2 from industrialized humans in the past 263 years: 1,480 billion tons.
Now, let's relate that to something a bit easier to visualize. A coniferous forest fire can release about 4.81 tons of carbon per acre. At the low end, about 80% of that carbon comes out as CO2.
In other words, to release an equivalent CO2 mass to the past 263 years of human activity would require about 1.5 billion acres of forest to burn every year during that time.
That's 6 million square kilometres of burning forest every year for more than two centuries.
Except that is for an average output, spread across 263 years.
Estimates of today's CO2 production go as high as about 40+ billion tons per year. That'd take something like 10 Billion acres of forest burning each year, which is about 42 million square kilometres.
The entire continent of Africa is a mere 30 million square kilometres. So AFRICA plus another third, on fire, each year...every year.
