According to the IMF, climate change could shave 11%-14% off global economic output by 2050 compared with growth levels without climate change. As per World Bank,global food insecurity could push an additional 100 million people into poverty by 2030. There is an urgent need to forecast climate with a greater accuracy that could better prepare us for risk mitigation. And now, scientists are creating a digital twin of the Earth that would be simulated in unprecedented detail to analyse the climate system in a way that has never been possible before.
