Scientists have scrapped the worst-case climate scenario – because action is making a difference
Ali Majdfar/Getty When major new climate change scenarios are released, there’s always strong interest. These scenarios lay out what our future climate will look like, depending on how fast we act to cut emissions. But what was surprising about the seven new scenarios announced last week was that United States President Donald Trump took an interest . Why? Because a high-emissions scenario – known as RCP8.5 and its successor SSP5-8.5 – had been removed. Under these worst-case
Scientists have removed the most extreme, worst-case climate change scenario from their latest projections. This scenario, which assumed no efforts to cut emissions and a significant increase in fossil fuel use, predicted a warming of around 4.5°C by 2100. The decision to exclude it reflects the tangible impact of global actions, such as the expansion of renewable energy and electric vehicles, which have slowed the growth of emissions. While this indicates progress in averting the most dire outcomes, scientists emphasize that emissions remain at record highs and global warming is accelerating.
This development matters because it highlights that human actions can influence climate trajectories, offering a more nuanced understanding of future possibilities beyond the most catastrophic predictions.
