In a May 16 Truth Social post, President Donald Trump cited updated climate change scenarios to misleadingly claim that experts had “admitted” prior climate change projections were WRONG! WRONG! WRONG!” The regularly scheduled revision reflects, in part, the progress the world has made on moving away from fossil fuels.
Trump was reacting to a new set of seven scenarios of emissions by the end of the century, proposed in an April 7 paper by an international group of scientists. Over time, the range of plausible scenarios has narrowed. The most pessimistic scenario now shows lower emissions than 15 years ago, when the prior scenarios were developed, while the most optimistic one now shows higher emissions.
Trump, however, used the update to cast doubt on the reality and seriousness of global warming. “GOOD RIDDANCE!” he wrote. “After 15 years of Dumocrats promising that ‘Climate Change’ is going to destroy the Planet, the United Nations TOP Climate Committee just admitted that its own projections (RCP8.5) were WRONG! WRONG! WRONG!”
RCP8.5 was the most pessimistic of four scenarios that were selected in 2007 and described in 2011. The scenarios looked at how much the climate might change by 2100, relative to the industrial revolution.
