'It's just summer, snowflake': BBC and Met Office weather forecasters reveal heatwave trolling

As Britain sweltered in record-breaking temperatures during the heatwave, weather forecasters suffered high levels of trolling on social media. Much of the abuse was directed at links between the 40C heat and climate change.

The BBC said its forecasters received hundreds of tweets or emails which were abusive. Today, it was reported that human-caused climate change made last week's record-breaking heatwave at least 10 times more likely, according to a study by a team of international scientists.

Much of the UK sweltered in the heatwave, with a new record temperature for the country of 40.3C set at Coningsby, Lincolnshire, 1.6C hotter than the previous record set just three years ago. The heat on July 18 and 19 caused widespread disruption to transport networks and hundreds of fires, including devastating blazes that destroyed homes, pushed London to the brink of blackouts and is expected to have caused hundreds of deaths.

The BBC's Matt Taylor said of the trolling: "It's a more abusive tone than I've ever received. I switched off a bit from it all as it became too depressing to read some of the responses."

Met Office lead meteorologist Alex Deakin was reported by the BBC saying: "I find it more frustrating and offensive for my colleagues - some of the great minds in climate science. Show a bit of respect and do a bit more research rather than just believe Bob down the pub or Tony on YouTube."

BBC meteorologist Tomasz Schafernaker told the BBC: "What frustrates me most is when I'm accused of twisting the truth. As meteorologists, we report facts. There is no conspiracy."

BBC Weather said: "It is completely unacceptable for any member of staff to receive abuse on social media simply for doing their job."

Typical trolling included terms such as 'it's just summer' and used terms such as 'snowflakes' and the 'woke-brigade', which the Met Office and BBC were accused of spreading alarm.

Examples of trolling included tweets saying: "Oh please. You were obviously never around in 1975/76. Get a grip." Another said: "When will you be apologising for such pathetic, absurd fear mongering nonsense? Or perhaps you should resign in disgrace."

Another, spreading misinformation, said the heatwave was created by "aircraft dispersing substances that blocked the sun and created a heat dome to trap heat within it in order to give off a greenhouse effect so gov can use these statistics to justify their climate change agenda"

Human-caused climate change made last week’s record-breaking heatwave at least 10 times more likely, according to a study by a team of international scientists. Scientists also warned that the UK’s extreme temperatures were higher than climate models predict – suggesting the consequences of climate change for heatwaves could be even worse than previously thought.

The 10-fold increase in the chances of such extreme heat in the UK as a result of climate change is a conservative estimate, the researchers from the World Weather Attribution initiative said. And while the searing heat, which saw temperatures peak above 40C for the first time in the UK, is still a very rare occurrence in today’s climate, it would be “almost impossible” without global warming.

Mariam Zachariah, from the Grantham Institute for Climate Change, Imperial College London, said: “Even with a conservative estimate, we see a large role of climate change in the UK heatwave. Under our current climate that has been altered by greenhouse gas emissions, many people are experiencing events during their lifetime that would have been almost impossible otherwise.”

The study looked at the annual maximum temperatures over two days across the region of England and east Wales which had the Met Office’s first ever red alert warning for extreme heat issued for July 18-19.

It also examined the change in frequency and intensity of the maximum daily temperature seen at three locations: London’s St James’s Park, Cranwell in Lincolnshire which is close to Coningsby, and Durham, where temperatures broke their previous record high by 4C.

Researchers used computer modelling to compare the likelihood of the temperatures seen in the 2022 heatwave under the current climate and in a world without the 1.2C of global warming seen since the 19th century.

The modelling suggests climate change, driven by more heat-trapping greenhouse gases put into the atmosphere by human activity, had made a heatwave as intense as the UK’s at least 10 times more likely and probably even more – though still only likely to happen once in 100 years.

Fraser Lott, climate monitoring and attribution scientist at the Met Office Hadley Centre, said: “Two years ago, scientists at the UK Met Office found the chance of seeing 40C in the UK was now one in 100 in any given year, up from one in 1,000 in the natural climate.

“It’s been sobering to see such an event happen so soon after that study, to see the raw data coming back from our weather stations.”

But the researchers also warned extreme heat in western Europe is rising faster than climate models predict.

While the models suggest climate change had increased temperatures in the heatwave by 2C, analysis of historical weather records indicate it would be around 4C cooler in pre-industrial times, before global warming started to drive up temperatures.

Friederike Otto, from the Grantham Institute for Climate Change, Imperial College London, said: “In Europe and other parts of the world we are seeing more and more record-breaking heatwaves causing extreme temperatures that have become hotter faster than in most climate models.

“It’s a worrying finding that suggests that if carbon emissions are not rapidly cut, the consequences of climate change on extreme heat in Europe, which already is extremely deadly, could be even worse than we previously thought.”

While it will take weeks for figures for the number of extra deaths seen during the heatwave, there have been estimates of more than 840 more people dying in England and Wales on July 18 and 19. The researchers warn older people, those with chronic health conditions and children are particularly vulnerable to extreme heat, with urban areas such as London seeing extra high levels of heat being trapped by the city.

There are also significant inequalities that worsen the situation, with poorer neighbourhoods in cities such as London lacking green space, shade, and water which can help people cope during heatwaves.

Climate change has increased average global and regional temperatures, which means natural spikes in heat are driven higher and occur more frequently.

It can also contribute to drier conditions and soils, which have been seen in much of Europe this year, which in turn exacerbate heatwaves because there is less water in the environment to absorb heat as it evaporates.
