Carbon dioxide spikes to critical record, halfway to doubling

Halfway to Doubling Preindustrial CO2What A Doubling of CO2 MeansWorrying Trends with Other Greenhouse GasesThe ImplicationsCarbon dioxide emissions are a product of electricity production, transportation and industry. The United States alone emits more than5 billion metric tons of CO2 annually — the weight of 13.2 million fully loaded Boeing 747s, or roughly68,000 Washington Monuments. Abouthalf of emitted CO2 remains in the atmosphereand induces warming, while more than a quarter is absorbed into the oceans, where it acidifies the water and disrupts marine ecosystems. There is special significance in reaching and surpassing a concentration of 416 parts per million. It means we’ve passed the midpointbetween preindustrial CO2 levels, around 278 parts per million, and a doubling of that figure, or 556 parts per million. The record of 421 parts per million reached Saturday is just a single point and occurred as CO2 levels are nearing their yearly peak. But the levels over the past two months, of more than 417 parts per million, signal that the annual average concentration is likely to exceed 416 parts per...Get price
