For years, environmentalists have campaigned for children to study global warming as a subject rather than simply as a part of geography. Their wish has now been granted in England with a new GCSE in natural history, starting from 2025. We know nothing yet about the syllabus but it’s quite the opportunity to ask what our planet’s problems really are, and how effective the net-zero agenda is as a solution. Rather than be scared to death about the future of the planet, pupils should instead be encouraged to take a rationalist approach. They might ask whether the obsession with climate change in recent decades has taken attention away from the many other major problems facing the planet.

A new report revealing that using wood pellets to generate electricity can actually speed up global warming should be the final nail in the coffin for the flawed policy of biomass subsidies. Policies designed to incentivise green energy use are not only having a dubious effect on climate change, they are destroying biodiversity and even killing many thousands of people. Wood (or to use the technical term covering wood, wood pellets and other burning matter like animal dung, biomass) is by far the most significant renewable energy source. In both the US and the EU, biomass is the single largest source of renewable energy. Owing to poverty, around three billion people globally cook and heat their homes with wood, twigs and dung.
