As we head towards COP21, the critical climate negotiations taking place in Paris in December, anyone invested in the Global Goals should think seriously about having the word SUSTAINABLE emblazoned on our foreheads. It should be front, back and centre of mind at all times because without the S factor we risk losing advances that have been fought for and undoing gains that have been won.
Come on, environmentalists. Don't hide behind the phrase 'green jobs'. If you want more renewables now, explain why you believe that environment trumps economics. If you believe that the UK should unilaterally lower our own carbon emissions immediately when the rest of the world isn't, and when our own action would be dwarfed by global trends, please tell us why. Make that case.
The advent of a strong voice from the medical profession, in the push for a meaningful climate treaty at the Paris Climate Summit in December, is hugely welcome. It is part of a multi-sectoral mobilisation that is offering increasing hope around the world that humankind can see off the climate-change threat, and spin its collective response into a global renaissance.
One of the rocks that climate change sceptics like to throw at those advocating action to tackle climate change is that it's all very well for the rich developed world to reduce its carbon footprint but it's immoral to ask the world's poor to give up cheap energy such as coal. Yes, climate change may be happening, they say, but it's unfair to pull up the fossil fuel ladder from developing countries.
