Carbon Levels Are Higher Than They've Been in Past 3 Million Years, Scientists Reveal
"It tells you where we're heading if we don't get serious about addressing climate change."
Apr 05, 2019
Human activity has helped cause carbon levels to rise to a rate that hasn't been seen on planet Earth in three million years, researchers have revealed.
A study published Wednesday by the Potsdam Institute for Climate Impact Research in Germany showed that the last time carbon dioxide was detected in the planet's atmosphere at the level it is now was during the Pliocene epoch, which took place 2.6 to 5.3 million years ago.
Authors of the report, which was published in Science Advances, warned that while global temperatures have not yet risen more than 2o Celsius (3.6o Fahrenheit) above industrial levels in the past three million years, they likely will if "climate inaction" on the part of world governments continues.
"It seems we're now pushing our home planet beyond any climatic conditions experienced during the entire current geological period, the Quaternary," said Matteo Willeit, lead author of the study, "a period that started almost three million years ago and saw human civilization beginning only 11,000 years ago. So, the modern climate change we see is big, really big; even by standards of Earth history."

The report suggested that sea levels could rise as much as 6.5 feet in the next 200 years if humans do not end fossil fuel drilling and carbon emissions. The last time carbon levels were where they are now, sea levels were 65 feet higher, according to the Potsdam Institute.
According to the computer simulation the Institute used in the study, CO2 levels "should not be higher than 280 parts per million without human activity."
Carbon levels are currently at 410 parts per million and rising.
The study was published about three months after youth around the world began holding weekly demonstrations demanding that their elected leaders pass meaningful legislation to end carbon emissions from human activity and shift to a zero-carbon economy.
As students in Ireland, Sweden, Uganda, and other countries gathered for another climate strike, the climate action group Defend Our Future tweeted that the Institute's study shows "there's no time to waste" for global leaders to take meaningful climate action.
We are at a crossroads
This country and this world are at a monumental crossroads. US voters have an opportunity to beat back the forces of fascism and confront the billionaires who are rigging the economy, our media system, and our democracy, making it increasingly impossible for ordinary people to get by. We’re not just talking about the election. We’re talking about what must be done once these fascist elements are vanquished from power. We need a bolder set of solutions than what either major party has so far been willing to offer and a working-class movement ready to fight like hell for it. Trump didn't emerge from nowhere. The conditions that fueled MAGA authoritarianism were created by decades of radical neoliberal economic policies and a corrupt political system dominated by corporate interests. They slashed taxes on the super-rich, promising that the benefits would trickle down. They said giveaways to the corporate titans would make life more affordable for the rest of us. It was all bullshit. And when a bitter, betrayed populace searches for someone to blame, right-wing demagogues have little trouble finding scapegoats. People know when they're being lied to, but you won't hear any of this from the corporate media. Only independent journalism—powered and funded by people who believe in building a better world—can deliver truly trustworthy daily news.
