In a recent study, it was revealed that the UK economy suffered a significant blow due to the heatwave experienced last month. The research suggests that approximately 24 million work hours were lost, amounting to a staggering £1.15 billion in economic losses.
During the heatwave period, temperatures soared to a record-breaking 37.7°C at Lingwood, Strumpshaw Hill on 26 June, surpassing a previous high set in 1976. This extreme weather event forced workers nationwide to either take time off or adjust their working hours during the week starting June 22. This heatwave was the second of three to impact western Europe within three months, causing widespread repercussions on various sectors including health, infrastructure, water resources, agriculture, and wildlife.
A survey conducted by the London School of Economics’ Grantham Research Institute on Climate Change and the Environment, in collaboration with the Euro-Mediterranean Centre on Climate Change (CMCC), analyzed the impact of the heatwave on working hours and routines. The study, based on responses from 1,950 British adults, indicated an average reduction of 0.47 hours in working hours during the last week of June. The economic cost of lost output was estimated by considering adjustments made by workers, with those in physically demanding jobs, such as construction and agriculture, reducing their hours more significantly compared to those in less demanding roles like academia.
The survey findings revealed that around 3.6% of respondents, roughly 1.25 million workers, did not work at all during the heatwave week, resulting in a potential additional eight million lost work hours and an estimated cost of £0.38 billion to the economy. Moreover, 87% of respondents reported experiencing health-related issues, with some reporting extreme symptoms like dizziness and fainting. Additionally, 5% sought medical attention, and around 3% reported work-related accidents or injuries, with many attributing these incidents to the weather.
Elizabeth Robinson, director of the Grantham Research Institute, emphasized the need for better adaptation to climate change, urging the government to take action to ensure workplace safety. Shouro Dasgupta, an environmental economist at CMCC, highlighted the disproportionate impact of extreme heat on outdoor and physically demanding workers, exacerbating existing inequalities in the labor force.
The study underscores the urgent need for proactive measures to address the challenges posed by extreme heat events to safeguard workers’ well-being, productivity, and the overall economy.
