Key facts
- Western Europe is experiencing a severe heatwave with temperatures exceeding 40°C.
- France and the UK have issued extreme heat warnings.
- Tragic deaths of children and elderly individuals have been linked to the intense heat.
- Experts attribute the heatwave to a jet-stream blocking event amplified by long-term warming, not El Niño.
- Europe is warming at more than twice the global average rate due to climate change.
Western Europe is currently enduring its third heatwave of the year, with temperatures soaring above 40°C in parts of France and the UK issuing extreme heat warnings. Tragically, the intense heat has been linked to the deaths of children and elderly individuals.
While the US National Oceanic and Atmospheric Administration (NOAA) has declared El Niño conditions are underway, experts argue that this natural phenomenon is not the primary driver of the current European heatwave. Ioanna Vergini, founder of WYF24, stated that El Niño's direct influence on European summer heat is weak and that the current event is a 'classic jet-stream blocking event acting on a record-warm background.' She described El Niño as a 'distraction' in this context.
El Niño typically impacts tropical regions more directly, causing flooding in South America and droughts in Australia and parts of Asia. Its effects on Europe are generally indirect, potentially leading to unsettled conditions later in the year. Climate scientists emphasize that human-made climate change is the significant amplifier of global temperatures, having already raised them by approximately 1.3-1.5°C compared to pre-industrial levels. Europe, in particular, is warming at more than twice the global average rate, with temperatures rising by around 2.5°C since pre-industrial times. This warming trend is compounded by factors such as reduced low-level clouds due to aerosol reduction, which previously acted as a cooling barrier.
