Halfway to doubling preindustrial CO2Carbon dioxide emissions are a product of electricity production, transportation and industry. It means we’ve passed the midpoint between preindustrial CO2 levels, around 278 parts per million, and a doubling of that figure, or 556 parts per million. ADADThe record of 421 parts per million reached Saturday is just a single point and occurred as CO2 levels are nearing their yearly peak. ADData obtained from glacial ice cores indicates that modern-day CO2 levels are higher than at any point in at least the past 800,000 years. The implicationsAt the midpoint toward doubling CO2 levels, the planet has already warmed more than two degrees (1 to 1.5 degrees Celsius).
