“At present, the atmospheric CO2 is about 392ppm. The earth can ideally withstand only 350ppm of CO2, which is considered the safe level by many scientists, including Nasa climate scientist James Hansen,” said the professor from Mahidol University in Thailand.
Worldwide campaigns have been ongoing as far as Siberia to create awareness of the 350 target, the Star paper quoted him as saying. “The global warming effect will see global temperatures rising by 2°C at 450ppm. This means ice in the North and South Poles will start melting more. We must act now to reduce carbon and protect the environment,” said Chirapol at Warisan Global’s Go green with e.N.V.Y: A GreenTech Entrepreneurship and Networking Session.
Preliminary data by the US National Oceanic and Atmospheric Administration (NOAA) showed the carbon dioxide figure stood at 392.04ppm as of June 2010. It was 389.43ppm in 2009 and 387.88ppm in 2008, he said. He deduced it would take less than 12 years to reach the 450ppm level.
