"Unprecedented CO2 Levels: A Glimpse into Earth's Distant Past"

A study published in Science reveals that current levels of atmospheric carbon dioxide (CO2) are the highest in 14 million years, surpassing any levels seen during human existence. The research, based on the most comprehensive analysis to date, warns that industrial capitalism has raised CO2 levels to 419 parts per million (ppm) from around 280 ppm since the industrial revolution. The study emphasizes the urgent need for action to reduce CO2 emissions, as failure to do so could result in levels reaching 600 to 800 ppm by 2100, with severe consequences for the environment and ecosystems. The report serves as a "call to action" to address the climate crisis and highlights the importance of sequestering carbon dioxide and reducing emissions to mitigate the long-lasting impacts.
