Delegates at the ongoing annual climate summit in Bonn will hopefully heed the warning by a United Nations agency that the atmosphere’s carbon dioxide (CO2) content has already reached an ominous level at which only meaningful and result-oriented climate action can avert a catastrophe. The latest Greenhouse Bulletin issued by the World Meteorological Organization just prior to the Bonn meet reveals that the CO2 accumulation has swelled in 2016 to the highest-ever 403.3 parts per million. This is 45 per cent above pre-industrial era levels and is growing at a rate 50 per cent faster than the average in the past decade. It can potentially raise the earth’s temperature by 3 degrees Celsius and the sea level by 10-20 metres to submerge several small island nations and large parts of other coastal countries. More importantly, it practically rules out meeting the Paris climate accord’s goal of keeping the temperature rise “well below 2 degrees Celsius”. The noxious ramifications of a rapidly altering climate are already evident. A study by leading journal The Lancet finds that weather-induced disasters are up 46 per cent since 2000 and labour productivity is down 5.3 per cent. The economic losses in 2016 were worth about $129 billion.
