Pontificating at a Green New Deal rally on Monday, Rep. Alexandria Ocasio-Cortez (D-NY), who just claimed on Sunday that her apocalyptic prediction in January that the world would end in 12 years unless serious action was taken to combat climate change had just been "dry humor," suddenly returned to her climate change hysteria, stating CO2 levels had reached the highest levels in recorded history and the last time the levels were this high "bacteria and diseases we have never seen before roamed the Earth." Ocasio-Cortez ranted, “It was reported today that this weekend for the first time in human history we have reached atmospheric levels of carbon at 415 parts per million. This has never been seen in recorded human history. In fact meteorologist Eric Holthaus and journalist said simply about this measurement, ‘We do not know a planet like this.’ The last time our planet hit 415 we were in the Pliocene period. Oceans were 90 feet higher. Bacteria and diseases we have never seen before roamed the Earth. Humans did not exist. We have never seen a planet like this. And a planet like this is exactly what we are going to get, and it is exactly what we are going to inherit from previous generations if we do not act positively now." Ocasio-Cortez Issues Another Apocalyptic Climate Rant. Is This More Of Her ‘Dry Humor’? Only one question here: What technology and devices were used to make this measurement during the Pliocene period? I didn't even know what the pliocene period was. So I looked it up. It was a time frame between 2 and 5 million years. The wheel wasn't even invented yet. Oceans were 90 feet higher? So why aren't oceans 90 feet higher today?
