Carbon emissions from the wildfires that have ravaged much of southeast Australia are a major driver of what are predicted to be record worldwide atmospheric CO2 levels throughout 2020, Britain’s Met Office said Friday. The annual rise of planet-warming CO2 levels is anticipated to be among the largest since measurements began in 1958, it said. CO2 levels, taken at the Mauna Loa observatory in Hawaii, fluctuate throughout the year due to weather patterns in the Northern Hemisphere. But the annual trend is inexorably upwards, with record CO2 levels anticipated in May of 417 parts per million (ppm).
