CO2 in Atmosphere is Now Highest Since Humans Came into Existence

This explains why the world has been a lot more warmer in recent years because heat has been trapped in carbon dioxide molecules.

On Saturday (May 11), the levels of the greenhouse gas reached 415 parts per million (ppm), as measured by the National Oceanic and Atmospheric Administration's Mauna Loa Observatory in Hawaii. He said the increase from past year will probably be around three parts per million whereas the recent average has been 2.5 ppm. There are other studies measuring greenhouse gasses like Methane who is also one of the main culprits of Carbon dioxide high levels. Sadly on another post based on Friday's measurement, he mentioned that "this is the first time in human history our plane's atmosphere has had more than 415ppm CO2". Scientists said it was extremely unlikely that the planet will ever drop below those levels again in our lifetimes. If the brink appears unremarkable (it shouldn't), it's one more indication of the unprecedented territory humanity is now charting because it blazes new trails towards environmental disaster. Going back even farther, here's a look at the Carbon dioxide levels of the past 800,000 years: It's clear that Earth has endured some significant changes to its Carbon dioxide levels in the past, occasionally even doubling for long stretches of time before calming down again. "The year-on-year increase of Carbon dioxide is getting steadily bigger as it has done throughout the whole of the 20th century", the Met Office's Dr. Chris Jones told BBC News. A study published in Nature well forecasted that if humans continued burning fossil fuels, then by the year 2250 we would be witnessing Carbon dioxide level at the same level as it was during the Triassic period some 200 million years ago.

The CO2 concentration level recorded on May 12 is far higher than any levels in more than 800,000 years of data or even before the Industrial Revolution period, where the highest recorded CO2 level was at 300 ppm.

There is excess carbon dioxide in the climate than what has been for about 800,000 years, before the human species advanced.

The macabre rise in carbon concentration levels isn't entirely surprising. Sea levels were also up by around 20 metres. But remember, it is not as if we haven't known about this impending crisis, is it? Given this track, climate scientists knew well in advance that crossing the mark of 415 PPM would not be very far off. "The long-term increase is due to human-related emissions, especially the emissions of our burning of fossil fuels".
