Atmospheric carbon dioxide levels have reached an unprecedented level, rising higher than any other time in the entirety of human existence, data from the Mauna Loa Observatory in Hawaii indicated.
"This is the first time in human history our planet's atmosphere has had more than 415ppm CO2," meteorologist Eric Holthaus stated, noting that it is far higher than any level recorded in the last 800,000 years, since before the evolution of homo sapiens.
"Not just in recorded history, not just since the invention of agriculture 10,000 years ago. Since before modern humans existed millions of years ago," Holthaus added.
High levels of CO2 in the atmosphere cause detrimental effects as it prevents the Earth's natural cooling cycle from functioning, traps heat near the surface and causes global temperatures to rise.
