Washington: Researchers have said that the average level of carbon dioxide has, for the first time, topped 400 parts per million for a full month in April.

They`ve said that it`s likely this record-breaking moment marks the first time in 800,000 years that the Earth`s atmosphere has featured so much CO2, discovery News reported.
James Butler, director of the Global Monitoring Division of NOAA`s Boulder-based Earth System Research Laboratory ( ESRL ), said in a statement that they continue to turn the dial up on this `electric blanket` of ours without knowing what the resulting temperatures will be.
