The world is already about 1.2°C hotter than it was in pre-industrial times. Given the lasting impact of greenhouse gases already emitted, and the impossibility of stopping emissions overnight, there is no way Earth can now avoid a temperature rise of more than 1.5°C. There is still hope that the overshoot may not be too big, and may be only temporary, but even these consoling possibilities are becoming ever less likely. the world’s average temperature might rise by more than 1.5°C. The grandees who met in Paris in 2015 at a climate conference like the one starting in Egypt next week ,they enshrined the goal of limiting global warming to about 1.5°C in the Paris agreement, which sought to co-ordinate national efforts to curb emissions of greenhouse gases. Who is derailing the climate efforts ?
