Bjørn Lomborg he claimed that green energy technologies are too expensive and energy inefficient, and we should frack more and reduce subsidies for renewable energy. I will try to tackle his points and clarify why I believe he is wrong on almost every single issue.
There are all sorts of positive reasons why the UK shouldn't leave the European Union: the freedoms afforded its citizens, the commitment to international co-operation, the environmental benefits it brings, the workers' rights it requires, the international status membership affords the UK, and so on.
When the Government published its aviation policy framework in draft form, it asked the right questions about noise, air quality and climate change, but the final version fails to deliver on these. It is disappointing that so few of the recommendations we and others made have been taken up by the Government.
Its clear what we need to do to avoid dangerous climate change; we must wean ourselves off fossil fuels, leave the remaining ones in the ground and make the big switch to renewable energy.
OK, don't freak out about what comes next. The growing environmental crisis, and especially those determined to do nothing about it, or even outright deny it, is in economic terms the modern equivalent of slavery. Before you report me to the Daily Mail, do hear me out, and please note my emphasis on economic.

Despite their importance, around 2-7% of global blue carbon sinks are lost annually - four times the rate of loss of rainforests. Building massive turbines near such resources will only exacerbate the damage and release huge amounts of CO2 into the atmosphere.
In many parts of the world incomes are increasing and ever more people are moving into cities. Lifestyles are changing. And so are diets.
No two artists have the same response to the sea.
This Earth Day, 22 April, many environmentalists will be advocating the three R's - recycling, reusing and reducing. While these actions are important and worthwhile, we would be better off focusing on a different letter: V for vegan.
The European Parliament's vote this week against delaying the release of some 900 million carbon allowances (known as the 'back-loading' proposal) is disappointing on several grounds.
We wrote a letter, which was published this weekend alongside an article in the Sunday Times. It calls on the government to re-instate caring for nature in the primary school curriculum for the benefit of children today and tomorrow. Sir David Attenborough called me up to let me know he would sign our letter.
As a cyclist myself, I congratulate Boris on scaling up his transport ambitions and recognising the benefits of making London a cycle friendly city; if just some of his plans go through, they will be a great victory for cycling in London. The plans however face many obstacles...
There is something irresistible about a free newspaper or magazine. Human nature is such that we can't help but pick them up, regardless of their qual...
