The measurements come after scientists recently warned that the world could continue to slide towards “catastrophic” climate change, even if greenhouse gas emissions were dramatically reduced and the government still failed to achieve them.
Ralph Keeling, a geochemist who oversees carbon dioxide measurements at the Scripps Institution of Oceanography in Hawaii, said: “It is unfortunate that we are not taking joint action to reduce carbon dioxide emissions.
He further added that in a statement issued by The Guardian, the British newspaper “may not be used.” Fossil fuels It’s still accelerating, but we’re still running at full speed towards a global catastrophe. “
Last May, the Mauna Loa Laboratory in the Hawaiian Islands measured the concentration of carbon dioxide at 421 parts per million, the latest increase in the level of this gas caused by the burning of fossil fuels and deforestation.
Prior to the Industrial Revolution in the 19th century, carbon dioxide levels on Earth were 280 parts per million for nearly 6,000 years, providing a solid basis for the progress of human civilization.
Since then, humans have released about 1.5 tons of carbon dioxide, enough to heat the planet for the next thousands of years.
According to the US Government’s National Oceanic and Atmospheric Administration, this huge improvement in carbon dioxide emissions is rapidly pushing the world to a state of non-existence in 4 million years.
“Our race has never seen carbon dioxide,” said Peter Dance, chief scientist at the department’s global monitoring laboratory.
He continued, “We have known about this for half a century and have failed to do anything meaningful about it. What do we need to wake up to?”
Carbon dioxide levels last peaked at 4.1 million years ago, at 400 parts per million.
The world at that time was completely different from what we know now because the forests were covered North Pole Also the sea level is 5 to 25 meters higher than it is today, which is enough to submerge many big cities in the world.
