1990 Climate Change Predictions Turn Out to Be Accurate
In a blow to those people who believe that global warming predictions are just a lot of hot air, an international team has established that predictions made 20 years ago are turning out pretty accurate. The report compares predictions from the first Intergovernmental Panel on Climate Change (IPCC) Assessment Report, published in 1990, with real-world global climate change data gathered since.
It’s the first time that IPCC estimates have been compared with real world changes, and should give more credence to the organization’s increasingly alarming predictions. Its next set of forecasts – based on much more refined computer models than those of 1990 – are due next year.
