Carbon Dioxide Levels on Earth Haven’t Been This High in Three Million Years. Futurism, Brad Jones
New Highs
The United Nations has issued a warning that last year, the concentration of carbon dioxide in the atmosphere increased at a rate that has never been observed before. Current levels have not been matched in over three million years.
The global concentration of carbon dioxide reached 403.3 parts per million (ppm) in 2016, up from 400 ppm in 2015. The rise can be attributed in part to the recent El Niño event, but the figures from the past several years reveal that this isn’t the only factor.
The increase of 3.3 ppm between 2015 and 2016 is greater than the 2.3 ppm rise between 2014 and 2015. Indeed, the annual increase over the past decade has been just 2.08 ppm. The last time there was a major El Niño event, in 1998, levels only rose by 2.7 ppm.
Environmental factors only tell a part of the story; human activity, too, is causing these levels to rise. The UN’s report states that population growth, intensive agriculture, deforestation, and industrialization are the biggest contributors to the changes taking place.
“Without rapid cuts in CO2 and other greenhouse gas emissions, we will be heading for dangerous temperature increases by the end of this century, well above the target set by the Paris climate change agreement,” said World Meteorological Organization chief Petteri Taalas, according to a report from The Guardian.
