Why temperature records are being not only broken but smashed

Western Europe is experiencing an unprecedented early-season heatwave, with hundreds of temperature records shattered across multiple countries. In the UK, temperatures exceeded 35°C in May, surpassing previous records by more than 2°C. France has seen a similar pattern, with its weather service, Météo-France, confirming hundreds of broken heat records. Other countries including Ireland, Germany, Italy, Spain, and Switzerland have also reported unusually high spring temperatures, driven by a persistent "heat dome" trapping warm air over the region. Scientists attribute the intensity and frequency of these heatwaves primarily to human-induced climate change, linked to the burning of fossil fuels such as coal, oil, and gas. Europe has warmed by approximately 0.56°C per decade over the past 30 years, more than twice the global average, making extreme heat events more severe and common. Experts emphasize that while heatwaves have always occurred, the current scale and early timing are far beyond historical norms, with records being broken by larger margins than expected. This trend is consistent with long-standing climate projections, though the speed and extremity of recent temperature spikes have surprised many researchers. Richard Betts, head of climate impacts research at the UK Met Office, noted that these developments align with warnings issued decades ago but are unfolding faster than anticipated. The phenomenon is not confined to Europe; for example, Delhi, India, recently experienced temperatures reaching 45°C, underscoring the global nature of rising heat extremes. The breaking and "smashing" of temperature records reflect a shifting climate baseline, where stable weather patterns no longer apply. As Erich Fischer, a climate science professor at ETH Zurich, explains, the increasing frequency and magnitude of new heat records indicate a fundamental change in the Earth's climate system, with serious implications for ecosystems, human health, and infrastructure worldwide.
