The BBC’s Science & Environment portal has been directing today’s visitors to a three year old article on a report claiming that farming needs a “climate-smart” revolution. The 2012 article, written by former BBC Environment correspondent Richard Black, gravely told readers that climate change was “forecast to reduce crop yields overall” and only by slashing greenhouse emissions could this catastrophe be stopped.

Three years later the UN is reporting that the world has an over-abundance of wheat supply and year-on-year record crop levels. Perhaps that article is due an update?
