Letter: Rachel Connolly is right to demand that the Labour leadership candidates address the climate crisis (The nuclear button? There really are more pressing issues, Journal, 8 January). But suggesting we remove nuclear weapons from the conversation ignores how intertwined these two existential threats are. Generations of climate scientists have documented that a nuclear war could cause drastic climatic disturbances and global famine. Last year scientists found that the use of a few hundred weapons (less than 10% of today’s global nuclear arsenals) could nearly stop all rain over India and central China, and reduce global precipitation globally by 15%-30%. It would take over a decade to return to rainfall levels before the nuclear war. Nuclear weapons destroy the climate even when they are not used. Nuclear weapons facilities – not unlike the oil and gas companies exacerbating the climate crisis – have contaminated land and water around the world with waste that will last far beyond even our grandchildren’s lifetimes.
