Jusqu'ici tout va bien

"With current global emission rates of 35 to 40 billion metric tons of CO2 each year, we may get our first glimpses of ice-free Septembers in the next 20 to 25 years, when we will have added another 800 billion metric tons to the atmosphere. Yet it does not stop there. Other months of the year will become ice-free with additional atmospheric CO2. For example, with another 1,800 billion metric tons of CO2, the Arctic will likely have no ice from July through October."
