‘Revised theory suggests carbon dioxide levels already in danger zone’
Despite continuous efforts from various quarters, the effects of global warming have been on an increase. Climate change, the biggest threat for humanity is at its peak. Reducing the emission of carbon dioxide is the hottest topic of discussion but nothing concrete has yet been achieved. Global warming, is a threat to our earth and the mankind and no one knows what awaits us in the future.
The revised theory suggests that the carbon dioxide level has already risen to dangerous highs and to combat climatic disasters, the levels of atmospheric carbon dioxide must be reduced below the levels it already exists. A study says:
to maintain a planet similar to that on which civilization developed, an optimum CO2 level would be less than 350 ppm — a dramatic change from most previous studies, which suggested a danger level for CO2 is likely to be 450 ppm or higher. Atmospheric CO2 is currently 385 parts per million (ppm) and is increasing by about 2 ppm each year from the burning of fossil fuels (coal, oil, and gas) and from the burning of forests. In short we have reached CO2 levels that compromise the stability f the polar ice sheets.
‘Climate cahnge causing natural disasters’
How fast ice sheets and sea level will respond to this, is still not understood properly, but given the potential size of the disaster, the best thing is not to learn this lesson firsthand.
