US scientists: carbon dioxide reached dangerous levels
US scientists said watching carbon dioxide levels in the atmosphere from Hawaii on Friday that the concentration of carbon dioxide in the atmosphere is higher in millions of years.
And increased the amount of carbon dioxide in the atmosphere steadily from 316 parts per million in 1958, when I started the measurements, to 400, according to the program of monitoring of carbon dioxide in the Scripps Institution of Oceanography.
Scientists believe that the last time where CO2 levels 400 ppm was between two and four million years ago. And sea levels rise during that period up to 131 feet.
He said the administrator of the network (CBS News) “we’re moving into a dangerous area.”
Ralph Keeling said he believes that efforts to reduce carbon dioxide emissions failed, and that some effects of climate change cannot be avoided.
He also said “there are many threats to human beings in these changes. We don’t know exactly how much is great but very unlikely to go beyond that without major disorder “.
Most scientists believe that the burning of fossil fuels is causing a rapid increase of carbon dioxide levels.
