CO2 Passes 415 PPM, Accelerating Crisis

Climate crisis: CO2 levels rise to highest point since evolution of humans; ‘We don’t know a planet like this’

Harry Cockburn, May 13, 2019 (UK Independent)

“Levels of the damaging greenhouse gas carbon dioxide have reached an alarming new milestone at the world’s oldest measuring station in Hawaii…The Mauna Loa observatory, which has measured the parts per million (PPM) of CO2 in the atmosphere since 1958, took a reading of 415.26ppm in the air on 11 May – thought to be the highest concentration since humans evolved…[Mauna Loa, on Hawaii’s largest volcano, tests air quality on the remote Pacific islands because it is far from continents and pollution, while the area lacks vegetation, which can interfere with results…The 1958 readings showed the concentration of CO2 was 313 ppm in March 1958…

…[This is reportedly the first time in human history earth’s] atmosphere has had more than 415ppm CO2… ‘We don’t know a planet like this,’ [meteorologist Eric Holthouse said of the reading. The] last time CO2 concentrations were this high was during the mid pliocene epoch 2.5 – 5 million years ago…During this period, global temperatures were 2 – 3C higher than they are today, global sea levels were at least 25 metres higher, and sea ice at the Arctic had retreated and given way to forests, where summer temperatures regularly reached 15C…” click here for more
