A New Scientist article by Bill McGuire reports that Earth is currently warming faster than at any point in its geological history. The piece argues that to understand where climate change is heading, we must look at past climate shifts preserved in sediments, ice cores, and fossil records. These show a clear cause-and-effect relationship between rising CO2 levels and temperature increases, with no ambiguity about the consequences. The article highlights that computer models are useful for projections, but the geological record provides direct evidence of how rapid warming has affected the planet before. As Europe faces what could be its hottest summer on record, the author stresses that the current rate of heating is historically unprecedented. For those tracking carbon markets and decarbonization timelines, this reinforces the urgency of cutting emissions now rather than relying on future technologies.
