The international goal to limit global heating to 1.5° Celsius is officially on life support. A United Nations-backed panel of climate scientists warned in a new report released Monday that the world may be on track to warm by more than 3°C — twice the Paris Agreement target —in a change that would painfully remake societies and life on the planet. The latest report from the Intergovernmental Panel on Climate Change comes after years of net-zero pledges by national governments, cities, businesses and investors, and it sounds a stark warning on the still-unchecked emissions of greenhouse gas emissions pushing to record levels. The focus of this report, the third released since August 2021, is on humanity’s vast arsenal of technology, know-how and wealth that remain insufficiently deployed in efforts to ensure a livable climate in the future.
