How to save the Earth

“What really concerns me is how far away scientific reality is from the reality of world politics.” This profound comment is from Joëlle Gergis, a lead author on the Intergovernmental Panel on Climate Change Sixth Assessment Report (“Dire warming”, August 14-20). Gergis says the world must reach net zero by 2050, and every country must raise their pledges to stay near the 1.5 degrees temperature limit. She concludes “the governments of the world” must agree soon at COP26 in Glasgow on the report’s safest scenario. Billions of years of evolution have produced a wondrous array of interdependent species. At this extraordinary, historic point in time, our leaders must make the wisest choice. – Barbara Fraser, Burwood, Vic
