Climate Change Disaster/ CO2 at Highest
Scientists in US have detected the highest levels of planet-warming carbon dioxide in the Earth's atmosphere since records began.
The Mauna Loa Observatory in Hawaii, which has tracked atmospheric CO2 levels since the late 1950s, on Saturday morning detected 415.26 parts per million (ppm).
The last time Earth's atmosphere contained this much CO2 was more than three million years ago, when global sea levels were several metres higher and parts of Antarctica were blanketed in forest.
Ralph Keeling, director of Scripps Institution of Oceanography's CO2 Programme, said the trend would probably continue throughout 2019 - likely to be an El Nino year in which temperatures rise due to warmer ocean currents.
The 2015 Paris Agreement calls on humanity to block the rise in Earth's temperature at "well below" 2 degrees compared to pre-industrial levels, and 1.5C if possible.
The last four years were the four hottest on record and, in spite of the Paris deal. Earth's average surface temperature has already increased 1C since pre-industrial times due to man-made emissions.
"Two years ago we hit 410ppm for the first time. By now, it's 415ppm. And oh, the increase is increasing at an increasing rate!"
