Global warming gas is around troubling level

Scientists are saying that the carbon dioxide has reached what they call troubling milestone. Monitoring stations diagonally the Arctic this spring are coming up with reading that say’s 400 parts per million of the heat-trapping gas in the atmosphere. The quantity isn’t quite a shock, because it’s been getting bigger at an accelerating pace. Years ago, 350 ppm mark is the safe level of carbon dioxide but not it has gone up to 390ppm.

As a result right now, merely the Arctic has reached that 400 level, but the rest of the world will go after soon.
Jim Butler, global monitoring director at the National Oceanic and Atmospheric Administration’s Earth System Research Lab in Boulder, Colo. Said “It’s just a reminder to everybody that we haven’t fixed this and we’re still in trouble.”

Some say the number will reduce a lot in the summer where the plants will intake a lot of carbon dioxide.
