Atmospheric Carbon Levels Are Reaching Dangerous Levels

By: Jon Queally of Common Dreams

Atmospheric levels of carbon registered 415 parts per million over the weekend at one of the world’s key measuring stations, a concentration level researchers say has not existed in more than 3 million years – before the dawn of human history.

Taken at the Mauno Loa Observatory in Hawaii by the Scripps Institution of Oceanography, the measure continues the upward trend of atmospheric carbon concentration that lies at the heart of the global warming and climate crisis:

415.26 parts per million (ppm) CO2 in air 11-May-2019 http://scripps.ucsd.edu/programs/keelingcurve/  First daily baseline over 415ppm

Writing on his Informed Comment blog Monday, historian Juan Cole said that life on Earth in that pre-historic era, known as the Pliocene Period, is not a place humans would recognize:

In the Pliocene, it was much hotter.

In the Pliocene, oceans were much higher, maybe 90 feet higher.

That is our fate, folks. That is what 415ppm produces. It is only a matter of time, and some of the sea level rise will come quickly.

Amsterdam, New Orleans, Lisbon, Miami – the list of cities that will be submerged is enormous.

Elsewhere online, reaction to the unsettling milestone was met with a mix of frustration, alarm, and fresh demands for urgent action to address the crisis.
