CO2 in the atmosphere just exceeded 415 parts per million for the first time in human history

The human race has broken another record on its race to ecological collapse. Congratulations humanity! For the first time in human history — not recorded history, but since humans have existed on Earth — carbon dioxide in the atmosphere has topped 415 parts per million, reaching 415.26 parts per million, according to sensors at the Mauna Loa Observatory, a research outpost of the National Oceanic and Atmospheric Agency. This is the first time in human history our planet's atmosphere has had more than 415ppm CO2. Not just in recorded history, not just since the invention of agriculture 10,000 years ago. Since before modern humans existed millions of years ago. We don't know a planet like this. https://t.co/azVukskDWr — Eric Holthaus …

Climate change kills off clouds over the ocean in new simulation

We all know climate change is affecting weather systems and ecosystems around the world, but exactly how and in what way is still a topic of intense study. New simulations made possible by higher-powered computers suggest that cloud cover over oceans may die off altogether once a certain level of CO2 has been reached, accelerating warming and contributing to a vicious cycle. A paper published in Nature details the new, far more detailed simulation of cloud formation and the effects of solar radiation thereupon. The researchers, from the California Institute of Technology, explain that previous simulation techniques were not nearly granular enough to resolve effects happening at the scale of meters rather than kilometers. These global climate models seem particularly …
