Since my childhood, I have been hearing the term ‘global warming’. But now after many years I could realize being terrified the very long term affect of it on to the climate. We had learned about ‘global warming’, ‘CFC gas’, ‘green house effect’, ‘carbon-di-oxide effect on climate’ from the beginning of our school life. But the matter of great regret, I couldn’t find anything now that resembles of being concerned about ‘Climate change’ of the earth.
Without further action to reduce greenhouse gas emissions, the global average surface temperature is likely to rise by a further 1.8-4.0°C this century, and by up to 6.4°C in the worst case scenario. Even the lower end of this range would take the temperature increase since pre-industrial times above 2°C – the threshold beyond which irreversible and possibly catastrophic changes become far more likely.
