THE CUBE: Los científicos del clima denuncian una oleada de acoso tras la última ola de calor

[00:00:03][music] >> Hello and welcome to the cube, Euronews' fact-checking show. Now, Europe has been experiencing [music] a spell of unusually hot weather, but alongside the heat, claims [music] casting doubt on climate scientists are also spreading online. This post, [music] viewed thousands of times, points to a major heatwave in 1921, arguing that extreme temperatures occurred long before modern cars, planes, or industrial emissions.

[00:00:29]Another post references the 1976 [music] heatwave in the UK, one of the country's hottest on record, claiming people just got on with it. This isn't disputed.

[00:00:38]Scientists agree that Europe experienced heatwaves long before modern concerns about climate change, but researchers say that still [music] does not contradict modern climate science. The debate today is not whether heatwaves have happened in the past, but whether a warming climate is making extreme temperatures more frequent, more intense, [music] and more likely than they otherwise would be. Likewise, a single historic heatwave cannot, on its own, prove [music] or disprove long-term climate trends. Other posts go further and allege that temperature records are unreliable because cities are warmer than rural areas, whilst [music] others accuse public bodies of manipulating temperature records. The first is a phenomenon known as the urban heat island effect, where urban areas can record higher temperatures than nearby rural regions >> [music] >> because buildings, roads, and concrete absorb and retain more heat. But this effect is already understood and accounted for in major global temperature data sets. Researchers compare measurements from thousands [music] of weather stations around the world and cross-check them. Different temperature data sets produced by different research organizations [music] show a similar trend of long-term warming, despite using different methodologies, meaning there is no evidence to suggest that global temperature records are being systematically manipulated [music] to exaggerate climate change.
