How we can limit global warming, and GPT-4's early adopters

Time is running short to limit global warming to 1.5 C (2.7 F) above preindustrial levels, but there are feasible and effective solutions on the table, according to a new UN climate report. Despite decades of warnings from scientists, global greenhouse-gas emissions are still climbing, hitting a record high in 2022. If humanity wants to limit the worst effects of climate change, annual greenhouse-gas emissions will need to be cut by nearly half between now and 2030, according to the report. That will be complicated and expensive. But it is nonetheless doable, and the UN listed a number of specific ways we can achieve it.
