Here is an extract from any article written by Mark Lynas in the Guardian Newspaper recently. He highlights some important problems which are preventing world governments from taking urgent action on this issue which is hardly getting a mention in the current political election mania.
"Alarmists and deniers need to climb out of their parallel trenches, engage with the developing world and work together to end the crisis
Depressingly, all this confirms what social psychologists have long insisted: that most people accept only scientific “facts” that are compatible with or which reinforce their political identities and world views.
Forget the political myths: here’s the hard reality. The emergence from poverty of the developing world is non-negotiable. Humanity will therefore double or triple energy consumption overall by 2050. Our challenge is to develop and deploy the technology to deliver this energy in as low-carbon a way as possible, probably using some combination of efficiency, renewables, next-generation nuclear and carbon capture. We need to pour vastly more resources into R&D, and put a significant international price on carbon.
But to make any of this happen we will need to recapture the climate debate from the political extremes. We must then work to come up with inclusive proposals that can form the basis of a social consensus that must last decades if it is to have any meaningful effect on the climate change crisis that faces us."
