Whatever the world's leaders decide at the Climate Change conference in Copenhagen, here's one positive spin-off from the attempt to save the planet: it has brought together British rabbis from different denomations to formulate a Jewish response. A paper on the eco-challenge has apparently jointly been drawn up by Rabbi Natan Levy, head of the (Orthodox) London School of Jewish Studies' social responsibility unit, Rabbi Shoshana Boyd-Gelfand, executive director of the Movement for Reform Judaism and Rabbi Jeremy Gordon of the New London (Masorti) Synagogue.
