The United Nations Framework Convention on Climate Change was agreed in 1992 to deal with the increasing atmospheric concentration of carbon dioxide. In 1992, carbon dioxide concentrations had reached 356 parts per million (ppm) compared to 286 ppm in the 1850s. Today, with 411 ppm of CO2, the world faces a climate emergency. Despite advances in renewable energy technology, fossil fuel use has continued to rise and emissions are still growing. Meeting the Paris Agreement’s goals, agreed to in 2015, appears increasingly hard.
