CO2 levels already in danger zone
Carbon dioxide levels in the atmosphere have entered the danger zone and must be reduced if climate disasters are to be averted,according to researchers.US, British and French scientists, including two from Yale, said in a study that optimum CO2 level should be less than 350 parts per million (ppm) – a dramatic change from most studies that have pegged the danger level for CO2 at 450 ppm or higher.Atmospheric CO2 is currently 385 ppm and is increasing by about two ppm every year from the burning of coal, oil, gas and forests.”This work … Continue Reading
