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.
I have a dream. It involves climate negotiators. They are bleary-eyed, exhausted, but happy. Nestled inside some grey building in the heart of Paris, they are weeping with relief at the result of all-night negotiations that leave climate campaigners like me elated, and the carbon-fuel lobbyists staring into the abyss, desolated.
One of the best solutions we have available is solar energy. The potential of solar is vast - it's a well-known fact that in one hour, enough sunlight strikes the earth to provide the world's energy needs for a whole year. Even Thomas Edison, inventor of the light bulb, said back in 1931, "I'd put my money on the sun and solar energy. What a source of power!
For all its merits, the true potential of British renewables seems to be thwarted at every turn by outdated policy and reactionary politics. If we're not careful, a perfect storm of populist, anti-green initiatives may run the risk of transforming one of the country's biggest up-and-coming sectors into a permanent PR sham.
An increasing number of micro businesses are working to develop the briquette's market - a charcoal substitute which reduces unsustainable consumption of wood. The case for promoting a widespread use of briquettes is a strong one: the current use of charcoal and firewood is contributing to wide-scale deforestation in many developing countries.
