This shows that we are not on the right track to protect the climate at all. The figures put the rise and is getting higher year after year, they must be stabilized, " says Wolfgang Lücht at the German klimatforskningsinstitutet PIK to the AFP if the data from the observatory on Mauna Loa.
During the holocene, the current geological epoch which lasted for 12,000 years, have levels in the atmosphere generally fluctuated between 180 and 280 parts per million. With the industrial revolution increased the levels to over 400, but higher than the 415,26, researchers have never observed.
is still in the higher end. Last year's increase will probably land at 3 parts per million, while the latest time, the pace has been at 2.5 parts per million per year, " says Ralph Keeling, director of koldioxidprogrammet at the Scripps Institution of Oceanography, to the AFP.
The record level is the latest in a line of signs that much remains to be done to halt and reverse the human activities negative impact on the climate. Researchers have different opinions about where the pain threshold, go for the atmosphere koldioxidnivå, but around the 350 parts per million is a broader consensus, and this level was exceeded thirty years ago.
