Computer simulations of global weather patterns will eventually be able to provide forecasts accurate to within a few kilometers, which will help in predicting the impact of dangerous weather events. However, it may take 20 to 40 years for this level of accuracy to be achieved as computer capabilities continue to advance. Alan Thorpe, director general of the European Center for Medium-Range Weather Forecasts, stated that in the future, climate models could potentially offer resolution down to a few kilometers, providing valuable information on climate variability. These models are computerized representations of the Earth's climate system, using physics and intricate equations. Models like this can be utilized for predicting weather, comprehending the climate, and forecasting climate change. The accuracy of the results produced by a model with a very detailed resolution depends on the capacity of the computer. Thorpe mentioned that some climate models are now reaching a resolution of 100 km, compared to approximately 300 km a decade or so ago. He stated that global weather picture models are already being run at a resolution of 16 km, indicating that the science and models exist to address the issue of high resolution, but the necessary computer power is lacking. Thorpe also noted that acquiring a top-of-the-line supercomputer could cost up to 200 million pounds, which is roughly 7 percent of the UK's annual science budget of 3 billion pounds. Thorpe emphasized the importance of recognizing the impact of climate change and allocating resources accordingly. Some experts caution that the most severe effects of climate change may occur between 2030 and 2050. Criticism has been directed towards certain climate models for their lack of accuracy and ability to predict extreme events far in advance. ECMWF scientists are specifically studying tipping points in the climate system, where rapid and potentially irreversible changes could occur. These non-linear behaviors are of particular concern and require careful attention. He stated that the exact number of those tipping points is still unknown. If all the science budget were dedicated to studying these questions, progress could be quicker, but research is currently being conducted in these areas. It is predicted that some tipping points will occur in the next few decades, such as the disappearance of summer Arctic sea ice or the destruction of the Amazon rainforest.
