“Record-setting” doesn’t do our CO2 levels justice. This chart does. 👆 Swipe for maximum devastation.
☁️ We’re officially living on a planet with an atmosphere no previous human being has ever experienced. You’ll probably be able to say the same thing tomorrow.
☁️ Carbon dioxide levels recorded at the Mauna Loa Observatory in Hawaii reached 415 parts per million on Friday. Not only is that the highest number the observatory has recorded since it first started analyzing atmospheric greenhouse gases in 1958, but it’s more than 100 ppm higher than any point in some 800,000 years of data scientists have on global CO2 concentrations.
☁️ This means levels of carbon dioxide in the atmosphere are now nearly 40 percent higher than ever in human history. And because the measurement directly correlates with things like global temperature and ocean acidification, this record concentration is further proof that humans are changing the environment at an unprecedented rate.
☁️ While it’s true that atmospheric carbon levels (and, by extension, global temperatures) have fluctuated a great deal throughout Earth’s geologic history, they’ve never done it this quickly. And they’ve never come close to current levels in the nearly 1 million-year snapshot of atmospheric data scientists have taken using the Mauna Loa Observatory and miles-deep ice cores from the poles. If there’s one graph that shows how alarming carbon emissions really are, it’s the one above that illustrates those findings.
