Urgent action needed to prevent climate collapse, says UN and IPCC.

The Intergovernmental Panel on Climate Change (IPCC) has said that avoiding the worst effects of climate change is still possible, and there are multiple feasible options for doing so. Finance and climate justice will be key, as the shift to a low-carbon economy will require three to six times the current amount of funding devoted to green investment. The IPCC report emphasizes that the poorest and most vulnerable people are being hit hardest by the impacts of the crisis. The UN Secretary-General called for countries to adopt an "acceleration agenda" involving all of the G20, and developed countries must bring forward their commitments on reaching net zero greenhouse gas emissions.
