Maureen J Anderson, writing on 14 January, criticises the money spent and the carbon emitted by the thousands of delegates attending the recent emissions trading scheme (ETS) conference in Mexico.
She clearly doesn't believe in ‘so called' global warming and accuses the conference of producing only ‘hot air'. Maybe so, but the fault surely lies with the thousands of people with similar beliefs denying the phenomenon of climate change driven by anthropogenic global warming. They are the unwitting disciples of the vocal sceptics campaigning to debunk ETS at any cost.
It is this attitude which has effectively undermined the resolve of so many governments to commit themselves to the cuts necessary to avoid future global catastrophe. Both Mexico, and Copenhagen before it, failed for this reason. That was the real waste.
I suggest that those who still don't believe the global climate is changing - and for the worse - observe the world around them.
The increasingly frequent extreme heatwaves and droughts, floods and storms, and even blizzards, just happen to fit the pattern predicted by scientists from escalating CO2 emissions many years ago.
