Above 1.5ºC, experts are extremely concerned that tipping-points will be crossed, causing irreversible loss of biodiversity and disruption to critical Earth systems, as well as impacting food security and loss of life in many communities around the world. Professor Dr Johan Rockström is director of the Potsdam Institute for Climate Impact Research, a leading climate research institution. Speaking at COP 28, he said: “It is really important to recognise that climate change and biodiversity loss is at such a global scale that we are now destabilising the global hydrological cycle. We are pushing it out of balance, and the latest estimates show that every 1ºC of global warming adds another 7% of moisture in the atmosphere.” As a lead author on The Global Commission on the Economics of Water report, Rockström said that the water issue “integrates across the whole economy in a way that we have completely underestimated, because not only is it in all the goods and services, it is also interconnecting nations”. This interconnection is linked through atmospheric rivers and through provisioning of rainfall. Rockström continued: “Argentina is entirely dependent on a
