Secretary General Guterres has set up a climate summit for September, with a new demand for earnestness: for a country to be invited, it will have to pledne to end licensing and funding of new oil and gas reserves and expansion of old ones. Bravo, Gutierres! It is heart-warming to see someone in a position of importance who recognizes what priorities are needed for survival.

With his influence, he has a chance of overcoming the power of fossil fools. It won't be easy to beat tham, but civilization depends on it, and every young person's life is at risk.
