銆€銆€It's Official: Atmospheric CO2 Just Exceeded 415 ppm For The First Time in Human History
銆€銆€Yet another alarming milestone of humanity's damaging effect on the environment has now officially been reached-crossing a barrier into a hot, polluted future like the planet hasn't witnessed in millions of years.
銆€銆€Sensors in Hawaii recorded Earth's atmospheric concentration of carbon dioxide (CO2) passing 415 parts per million (ppm) for the first time since before the ancient dawn of humanity.
銆€銆€Last Saturday, CO2 concentration recorded at the Mauna Loa Observatory in Hawaii by researchers from the Scripps Institution of Oceanography hit 415.26 ppm – the latest in a dire series of climatic thresholds being breached by a human society that refuses to relinquish the conveniences afforded by fossil fuels.
銆€銆€"This is the first time in human history our planet's atmosphere has had more than 415 ppm CO2," meteorologist Eric Holthaus tweeted.
銆€銆€"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. We don't know a planet like this."
銆€銆€It was only a few years ago that carbon pollution in the atmosphere soared past 400 ppm, and it didn't take long much longer to reach 410 ppm (in 2017).
銆€銆€In fact, with this record-breaking surge in atmospheric carbon poisoning the skies and trapping Earth's heat, scientists knew hitting 415 ppm in 2019 was all but inevitable.
