The article looks at ways to measure the impact of gases in fridges that can make global warming worse. These gases, called F-gases, are used a lot in air conditioners. The current measure of their impact doesn't consider how long each gas stays in the air, which is a problem. A new study suggests a different way to measure their effect called GWP*. This study used a model to show that the usual way of measuring, based on CO2, doesn't exactly show how these gases heat up the atmosphere. By using the new measure, the study showed that cutting the emissions of one common F-gas could help reduce warming faster. This new approach could be helpful in figuring out how to decrease the impact of these gases on global warming in a quicker way.
